siology,” by F. S. Lee; “Notes on recently discovered deposits of

December 4.—Protessor H. F. Osborn described and exhibited a 
series of restorations of lower Miocene mammals including Titanothe- 
rium, Aceratherium, Metamynodon, Protapirus, Elotherium, Oreodon 
and other characteristic forms. This is the first uf a series of tertiary 
mammal groups in preparation. 
Mr. O. L. Strong described a new modification of the rapid Golgi 
method designed to eliminate some of its present defects, i. e., uncer- 
tainty of success and irregularity in thestain when attained, due prob- 
ably in great measure to the feeble penetration of the silver nitrate. 
The modification consisted in adding a certain proportion of sodium 
sulphate to the silver nitrate which the specimens are placed after the 
hardening in osmic-bichromate. 
While this modification has hardly been tried sufficiently to ascer- 
tain exactly its merits, it seemed certain that in some cases, at least, it 
gave much more complete and uniformly stained pictures of the ner- 
vous system than the old procedure. 
Specimens of the heart of a tadpole and cord of an embryo chick 
were exhibited. 
Professor E. B. Wilson noted a mode of preparation of lobster testis 
which gave results especially favorable for class work in Cytology.
