nearly always records the morning temperature, and also makes 
mention of all extraordinary meteorological changes. His Ann 
Arbor observations were finally worked up under the auspices of 
the Smithsonian Institution, and also by himself in connection 
with the geological survey of the state. 
1856. He read a paper, in 1856, before the State Teachers’ 
Association; On the importance of the Study of Natural History, 
in which he advocated the introduction of these studies into the 
Union schools and the lower classes of the colleges. He read 
also papers before the American Association for the Advancement 
of Science, at Albany, N. Y., on the Geology of Middle and 
Southern Alabama, and Statistics of some Artesian wells of Ala- 
bama.* Much attention was given also this year (1856) to micro- 
‘scopical studies; and a large number of drawings in colors were 
executed with the camera lucida. 
1857. In the early part of 1857, he contributed, by invitation, 
a series of seven articles on Popular Education, under the signa- 
ture of ‘‘Scholasticus,”’ to the Detroit Tribune. In one of these, 
having animadverted on the ‘‘Prussian system,” president Tap- 
pan put in a reply, extending over several numbers of the paper, 
Tt was stated at the time that the first articles emanated from the 
president of Kalamazoo College, Dr. Stone, and that president 
Tappan imagined himself replying to him. 
At the request of Mr. B. F. Meek he made out a general table 
of the Cretaceous rocks of Alabama, which has entered perma- 
nently into the literature of the Cretaceous system.t He pub- 
lished this year also A Guide to the Pronunciation of Scientific Terms 
—a pamphlet intended for his own students, but which had quite 
a circulation among scientific men, until the edition was exhausted. 
During the summer of 1857 he made a minute microscopic in- 
vestigation of Lumbriculus, with colored drawings and descrip- 
tions. Inthe autumn and winter he drew up a detailed deserip- 
tion of the osteology of Marobranchus (Necturus) lateralis. He 
opened in the autumn a class in comparative osteology, which was 
attended by about eighteen students from the Medical College, 
besides those from the Literary department. In subsequent years 
the professor of anatomy instituted a similar course for the medi- 
cal students.
