I remember one day his holding up a small vial in each hand, explaining elaborately the contents of each, and what the chemical effect would be when the two should be poured together. The class watched in breathless attention. "Now, young ladies," and the bottles were lifted high that all might see, "you will observe"--repeating the formula--and then pouring them with quick, deft movement together. Nothing happened. Who that saw it but must remember the blank amazement of the professor's face and the hearty laugh all round in which he joined. "Well, that never turned out so with me before." Beyond the center south where are now the candy-kitchen and day students' parlor was the natural history lecture and classroom. The cabinets of minerals were beautifully arranged in a long gallery on the fifth center and consulted there as occasion required. The story goes that a student busy with her topic one day was interrupted by the entrance of a visitor who patronizingly asked, "Well, what are you so absorbed in?" She raised her eyes. "The odontology of the bison, sir." He fell back a few paces, gazed at her in silence a moment, and then left the room. The collections of birds, shells, etc., were placed on the third corridor center in rooms now devoted to student use. A domestic in employ of the college, whose special charge was the natural history classroom, was noticed gazing at the wall where hung engravings of some huge mammals of prehistoric time. "Were those rale bastes, Professor?" He assured her that such once lived, whereupon she commented complacently, "Well, I s'pose the men and women then were equal to 'em." The Venus of Milos stood in the gymnasium, and two workmen had been sent to change slightly its position. One was overheard asking why the surface of the statue was so chipped and rough. His companion answered with an air of finality, "The Doctor uses this to illustrate her lectures on skin diseases." Space fails to recount all the little jokes. "Bacchanalian Sunday" a young student called Baccalaureate in perfect good faith. "I am glad the old Main looks unchanged inside as much as it does. I should say those were the same old water tanks, had you not told me otherwise. I used to room in this parlor here, and wonder if I could find my name with those of my roommates still written on the inside shutters?" And she did. But the alumna returning after a long period of years does find many changes, concerning chiefly the routine of daily life, manners and customs, what was known in her time having disappeared almost entirely. Let us begin with the first schedule of the college hours:
