From Chapter 11:
Sidgwick's praise of tobacco, classically draped in Greek verse, occasionally of the macaronic order, is delightful. He hails the pipe as the work of Pan, and the divine smoke as the best and most fragrant of gifts—healer of sorrow, companion in joy, rest for the toilers, drink for the thirsty, warmth for the cold, coolness in the heat, and a cheap feast for those who waste away through hunger. How is it, he says, that through so many ages men, who have need of thee, have not seen thy nature? Often, he continues—the verses may be roughly translated—often, when I am in Alpine solitudes, tied in a chain to a few companions, clinging to the rope, while barbarians lead the way, carrying in my hands an ice-axe and breathless crawling up the snow-covered plain—then, when groaning I reach the summit (either pulled up or on foot), how have I rested, on my back on the rocks, charming my soul with thy divine clouds! He goes on in burlesque strain to speak of the joys of tobacco when he lies in idleness by the streams in breathless summer, comforted by a bath just taken, or when in the middle of the night he is worn out by revising endless exercises, underlining the mistakes in red and allotting marks, or weighed down by the wise men of old—Thucydides, Sophocles, Euripides, the ideas of Plato, wiles of Pindar, fearfully corrupt strophe of chorus, wondrous guesses of Teutons and fancies of philologists, when men swoon in the inexplicable wanderings of the endless examination of Homer, when the brain reels among such toil—then he hails the pipe, help of mortals, and hastens to kindle sacrifices at its altars and rejoices as he tastes its smoke. Let some one, he exclaims, bring Bryant and May's fire, which strikes a light only if rubbed on the box—

From Chapter 14:
Evidently the intention was to make things pleasant for the royal foe of tobacco during his visit. It would appear to be a fair inference from the wording of this prohibition that when the King was not at Cambridge, graduates and scholars and students could resume their liberty to resort to inns, taverns, ale-houses and tobacco-shops, and presumably to take tobacco in St. Mary's Church, without question.

The prohibition, in the regulation quoted, of smoking in St. Mary's Church, referred, it may be noted, to the Act which was held therein. Candidates for degrees, or graduates to display their proficiency, publicly maintained theses; and this performance was termed keeping or holding an Act.
It is, of course, conceivable that the prohibition, so far as the church and Trinity College Hall were concerned, was against the taking of snuff rather than against smoking; but the phrase "to take tobacco" was at that time quite commonly applied to smoking, and, considering the extraordinary and immoderate use of tobacco soon after its introduction, it is not in the least incredible that pipes were lighted, at least occasionally, even in sacred buildings.
