important a role they play in life, and that his very continuance in 
life depends upon their presence in, or absence from, his system ; 
and he will be delighted with the new world of knowledge presented 
to him. A new science has been created, that of mycology, which 
to-day is exciting more general interest, and engaging more thought 
and study, than most of the older sciences. A new literature of 
surprising extent and variety is being created, and so eager and 
numerous are those who occupy their time with it, and so steady is 
the stream of their discoveries, that we seem to be but on the 
threshold of what we are to know in the near future —Allan, in 
Independent Practitioner. 
Tue firm of W. H. Walmsley & Co., of Philadelphia, has been 
dissolved. Mr. Walmsley’s former partners, Messrs. Earle & 
Collins, will continue the business, and will remain the sole

THE special internal anatomy of the Uropoda krameri is 
described by Albert D. Michael, F. Z. S., in the February issue of 
the Royal Microscopical Journal. In the same journal a list of the 
desmids from Massachusetts is published by Mr. William West, 
from specimens furnished by Mr. J. M. Lyle, of Amherst College. 
Both of the above papers are illustrated. 
Grorce S. Atzan, D. D. S., of New York, contributes an 
article on The Etiology of Dental Caries to the March Interna- 
tional Dental Journal. Of the Heitzmann-Abbott theory, he says 
“it is fallacious from the foundation up.” 
Tue last-written examination questions propounded to the senior 
class of the St. Louis College of Pharmacy, for the prize in micros- 
copy, are a model of their kind; and the practical work demanded 
of the student in this connection, indicates the thoroughness with 
which botanical microscopy is taught at this institution. 
In is remarks on the transmission of disease from animals to 
man, Prof. Walley states that, in his opinion, tuberculosis might be 
transmitted by fowls’ eggs. A report of this interesting discussion 
is printed in the Journal of Comparative Medicine and Surgery, 
October, 1888.
