Principles of Geology (1832), Vol. 1
Context: The most remarkable work of that period was published by Steno... The treatise bears the quaint title of 'De Solido intra Solidum contento naturaliter (1669,)' by which the author intended to express 'On Gems, Crystals, and organic Petrifactions enclosed within solid Rocks.'... Steno had compared the fossil shells with their recent analogues, and traced the various gradations from the state of mere calcification, when their natural gluten only was lost, to the perfect substitution of stony matter. He demonstrated that many fossil teeth found in Tuscany belonged to a species of shark; and he dissected, for the purpose of comparison, one of these fish recently taken from the Mediterranean. That the remains of shells and marine animals found petrified were not of animal origin was still a favorite dogma of many, who were unwilling to believe that the earth could have been inhabited by living beings long before many of the mountains were formed.

Discussing the result of an experiment where about 1 out of 8000 alpha particles were scattered backwards when fired at a thin sheet of metal foil, which led to the discovery of the atomic nucleus, as quoted in Rutherford and the Nature of the Atom (1964) by E.

Context: It was quite the most incredible event that has ever happened to me in my life. It was almost as incredible as if you fired a 15-inch shell at a piece of tissue paper and it came back and hit you.
Letter to his brother Jeff from Guadalcanal (28 January 1943); p. 25
To Reach Eternity (1989)
Context: I wasn't hit very badly — a piece of shrapnel went thru my helmet and cut a nice little hole in the back of my head. It didn't fracture the skull and is healed up nicely now. I don't know what happened to my helmet; the shell landed close to me and when I came to, the helmet was gone. The concussion together with the fragment that hit me must have broken the chinstrap and torn it off my head. It also blew my glasses off my face. I never saw them again, either, but I imagine they are smashed to hell. If I hadn't been lying in a hole I'd dug with my hands and helmet, that shell would probably have finished me off. The hole was only six or eight inches deep, but that makes an awful lot of difference, and it looked like a canyon.

Context: "The perfect ghost story is the story of Possession," he said, "and that is hypnotism from beyond the grave. This is possible since hypnotism is by the will, and the will is immortal. A number of notable men have been possessed, and all of their lives seem to fit a pattern: the inconsequential early years, the hiatus when they stood where Faust stood, and the decision. And then the rise to power and influence and almost universal honor after they have made the deal. But it is not themselves, it is the devils within them that gain these things. They are the possessed men who do much of the running of the world, and theirs is the most frightening story that can be imagined. But those who watch the great men do not know that they are shells inhabited by ghosts."

Chpt.3, p. 38
Principles of Geology (1832), Vol. 1
Context: His [Hooke's] principal object was to account for the manner in which shells had been conveyed into the higher parts of 'the Alps, Apennines, and Pyrenean hills, and the interior of continents in general.' These and other appearances, he said, might have been brought about by earthquakes, 'which have turned plains into mountains, and mountains into plains, seas into land, and land into seas, made rivers where there were none before, and swallowed up others that formerly were, &c. &c.; and which, since the creation of the world, have wrought many great changes on the superficial parts of the earth, and have been the instruments of placing shells, bones, plants, fishes, and the like, in those places, where, with much astonishment, we find them.' This doctrine, it is true, had been laid down in terms almost equally explicit by Strabo, to explain the occurrence of fossil shells in the interior of continents, and to that geographer, and other writers of antiquity, Hooke frequently refers; but the revival and development of the system was an important step in the progress of modern science.

Chpt.3, p. 37
Principles of Geology (1832), Vol. 1
Context: Respecting the extinction of species, Hooke was aware that the fossil ammonites, nautili, and many other shells and fossil skeletons found in England, were of different species from any then known; but he doubted whether the species had become extinct, observing that the knowledge of naturalists of all the marine species, especially those inhabiting the deep sea, was very deficient. In some parts of his writings, however, he leans to the opinion that species had been lost; and in speculating on this subject, he even suggests that there might be some connection between the disappearance of certain kinds of animals and plants, and the changes wrought by earthquakes in former ages. Some species, he observes with great sagacity, are peculiar to certain places, and not to be found elsewhere. If, then, such a place had been swallowed up, it is not improbable but that those animate beings may have been destroyed with it; and this may be true both of aerial and aquatic animals: for those animated bodies, whether vegetables or animals, which were naturally nourished or refreshed by the air, would be destroyed by the water, &c.; Turtles, he adds, and such large ammonites as are found in Portland, seem to have been the productions of the seas of hotter countries, and it is necessary to suppose that England once lay under the sea within the torrid zone! To explain this and similar phenomena, he indulges in a variety of speculations concerning changes in the position of the axis of the earth's rotation, a shifting of the earth's center of gravity, 'analogous to the revolutions of the magnetic pole,' &c.; None of these conjectures, however, are proposed dogmatically, but rather in the hope of promoting fresh inquiries and experiments.

"Counter-Attack"
The Counter-Attack and Other Poems (1918)
Context: Mute in the clamour of shells he watched them burst
Spouting dark earth and wire with gusts from hell,
While posturing giants dissolved in drifts of smoke.
He crouched and flinched, dizzy with galloping fear,
Sick for escape,— loathing the strangled horror
And butchered, frantic gestures of the dead.

“Old Hundredth” p. 162 (originally published in New Worlds Science Fiction #100, November 1960)
Short fiction, Who Can Replace a Man? (1965)
Context: When the first flint, the first shell, was shaped into a weapon, that action shaped man. As he molded and complicated his tools, so they molded and complicated him. He became the first scientific animal. And at last, via information theory and great computers, he gained knowledge of all his parts. He formed the Laws of Integration, which reveal all beings as part of a pattern and show them their part in the pattern. There is only the pattern; the pattern is all the universe, creator and created.

Context: My privilege is to be spectator of my life drama, to be fully conscious of the tragi-comedy of my own destiny, and, more than that, to be in the secret of the tragi-comic itself, that is to say, to be unable to take my illusions seriously, to see myself, so to speak, from the theater on the stage, or to be like a man looking from beyond the tomb into existence. I feel myself forced to feign a particular interest in my individual part, while all the time I am living in the confidence of the poet who is playing with all these agents which seem so important, and knows all that they are ignorant of. It is a strange position, and one which becomes painful as soon as grief obliges me to betake myself once more to my own little rôle, binding me closely to it, and warning me that I am going too far in imagining myself, because of my conversations with the poet, dispensed from taking up again my modest part of valet in the piece. Shakespeare must have experienced this feeling often, and Hamlet, I think, must express it somewhere. It is a Doppelgängerei, quite German in character, and which explains the disgust with reality and the repugnance to public life, so common among the thinkers of Germany. There is, as it were, a degradation a gnostic fall, in thus folding one's wings and going back again into the vulgar shell of one's own individuality. Without grief, which is the string of this venturesome kite, man would soar too quickly and too high, and the chosen souls would be lost for the race, like balloons which, save for gravitation, would never return from the empyrean.

“The shell must break before the bird can fly.”
From The Ancient Sage (1885), line 154

“Lister, to his accurate account of British shells, in 1678, added the fossil species,”
Chpt.3, p. 35
Principles of Geology (1832), Vol. 1
Context: Dr. Plot, in his 'Natural History of Oxfordshire.' (1677) attributed to a 'plastic virtue latent in the earth' the origin of fossil shells and fishes; and Lister, to his accurate account of British shells, in 1678, added the fossil species, under the appellation of turbinated and bivalve stones. 'Either,' said he, 'these were terriginous, or if otherwise, the animals they so exactly represent have become extinct. This writer appears to have been the first who was aware of the continuity over large districts of the principal groups of strata in the British series, and who proposed the construction of regular geological maps.

Letter to Bess Wallace (8 September 1918) https://www.trumanlibrary.org/whistlestop/study_collections/ww1/documents/fulltext.php?documentid=1-15
Context: Now days battles are just sort of a "You shoot up my town and I'll shoot up yours." They say that Americans don't play fair. They shoot 'em up all the time. I hope so because I want to finish this job as soon as possible and begin making an honest living again... Have fired 500 rounds at the Germans, at my command, been shelled, didn't run away thank the Lord and never lost a man. Probably shouldn't have told you but you'll not worry any more if you know I'm in it than if you think I am. Have had the most strenuous work of my life, am very tired but otherwise absolutely in good condition physically mentally and morally... When a High Explosive shell bursts in fifteen feet and does you no damage, you can bet your sweet life you bear a charmed life and no mistake. I didn't have sense enough to know what was going on until the next day and then I was pretty scared. The men think I am not much afraid of shells but they don't know. I was too scared to run and that is pretty scared.

(1832) Vol.1 Chpt.2, p. 20
Principles of Geology (1832), Vol. 1
Context: Strabo,... enters largely, in the Second Book of his Geography, into the opinions of Eratosthenes and other Greeks on one of the most difficult problems in geology, viz., by what causes marine shells came to be plentifully buried in the earth at such great elevations and distances from the sea. He notices, amongst others, the explanation of Xanthus the Lyclian, who said that the seas had once been more extensive, and that they had afterwards been partially dried up, as in his own time many lakes, rivers, and wells in Asia had failed during a season of drought. Treating this conjecture with merited disregard, Strabo passes on to the hypothesis of Strato, the natural philosopher, who had observed that the quantity of mud brought down by rivers into the Euxine was so great, that its bed must be gradually raised, while the rivers still continued to pour in an undiminished quantity of water. He therefore conceived that, originally, when the Euxine was an inland sea, its level had by this means become so much elevated that it burst its barrier near Byzantium, and formed a communication with the Propontis, and this partial drainage had already, he supposed, converted the left side into marshy ground, and that, at last, the whole would be choked up with soil. So, it was argued, the Mediterranean had once opened a passage for itself by the Columns of Hercules into the Atlantic, and perhaps the abundance of sea-shells in Africa, near the Temple of Jupiter Ammon, might also be the deposit of some former inland sea, which had at length forced a passage and escaped.

Early career years (1898–1929)
Context: I do not understand this squeamishness about the use of gas. We have definitely adopted the position at the Peace Conference of arguing in favour of the retention of gas as a permanent method of warfare. It is sheer affectation to lacerate a man with the poisonous fragment of a bursting shell and to boggle at making his eyes water by means of lachrymatory gas. I am strongly in favour of using poisoned gas against uncivilised tribes. The moral effect should be so good that the loss of life should be reduced to a minimum. It is not necessary to use only the most deadly gases: gases can be used which cause great inconvenience and would spread a lively terror and yet would leave no serious permanent effects on most of those affected … We cannot, in any circumstances acquiesce to the non-utilisation of any weapons which are available to procure a speedy termination of the disorder which prevails on the frontier.

Chpt.3, p. 26
Principles of Geology (1832), Vol. 1
Context: The excavations made in 1517, for repairing the city of Verona, brought to light a multitude of curious petrifactions, and furnished matter for speculation to different authors, and among the rest to Fracastoro, who declared his opinion, that fossil shells had all belonged to living animals, which had formerly lived and multiplied, where their exuviæ are now found. He exposed the absurdity of having recourse to a certain 'plastic force,' which it was said had power to fashion stones into organic forms; and, with no less cogent arguments, demonstrated the futility of attributing the situation of the shells in question to the Mosaic deluge, a theory obstinately defended by some. That inundation, he observed, was too transient, it consisted principally of fluviatile waters; and if it had transported shells to great distances, must have strewed them over the surface, not buried them at vast depths in the interior of mountains. His clear exposition of the evidence would have terminated the discussion for ever, if the passions of mankind had not been enlisted in the dispute; and even though doubts should for a time have remained in some minds, they would speedily have been removed by the fresh information obtained almost immediately afterwards, respecting the structure of fossil remains, and of their living analogues.
