dinary deposit of mould. On others the disease germs had de- 
veloped into thin, peculiarly shaped patches of fungous growth 
of bright blue, red, yellow, and greenish colors. Others had 
grown into an intricate and extensive network of fuzzy fibers, 
the growth on the surfaces of two or three potatoes reaching 
over and covering a space having a diameter of eight or nine 
inches. 
Some THoucuts AsBour Mountirne.—Discussion of various 
media.—‘Some experiments by Mr. E. E. Read, of the Camden 
Microscopical Society, would seem to indicate that cosmoline 
may prove a valuable medium in which to mount the starches. 
The starch grains are certainly remarkably well displayed in it. 
How permanent the mounts may prove is a question of time. 
It is not improbable that several of the petroleum products— 
even the plebeian kerosene itself—may be found not unworthy 
of the microscopist’s attention.” ‘Dr. W. W. Munson some 
time ago called attention to the preservative properties of a 
solution of chloral, and the medium is evidently deserving of 
more attention than it has had. A slide of algae put up in this 
solution over four years ago still remains as bright and pure as 
when first mounted, and, what is quite important, the cell con- 
tents of the algz appear to be less contracted than is usually 
the case.” 
In last week’s issue of Detroit Every Saturday, Mrs. C. H. 
Stowell makes an effective reply to the assertion made by Mrs. 
Stone in her “club talks” in that paper, that the opportunities 
for social culture afforded young ladies at the University are 
insufficient. Mrs. Stowell points out the many occasions for 
making acquaintances that are presented by the choral union, 
the church societies, receptions and entertainments, local soci- 
eties and the numerous class socials, suppers and meetings. 
She reaches the almost. unavoidable conclusion that if a Uni- 
versity girl fails to acquire social accomplishments, the blame 
rests upon the girl herself. In concluding her letter Mrs. Stow- 
ell says: ‘Mrs. Stone has certainly been misinformed on some 
of these matters; for instead of this great want being unsup- 
plied, it is supplied in such abundance that all the advocates of 
rigid study to-day fear lest the social life of the college girl will 
become so great that she will be unable to maintain the high 
standing she has so grandly acquired.”— Register.
