fully combated, and a commission sent to inquire into the results of his 
methods found that the cattle which he rendered immune did not die ; 
while those which he had not touched died from this fell disease. So 
successful were his experiments on anthrax, that he turned his attention 
to what is perhaps the most dreaded of all human diseases, and he was 
successful in discovering a method by which hydrophobia could be 
almost always successfully combated. These 
are some of the greatest benefits which this 
great man bestowed not only on France, but on 
the world ; and richer as mankind is by his 
life’s work, the poorer do we feel it to-day to 
be by his death. 
Professor Ryder. — Although Prof. J. A. 
Ryder was not an Honorary Fellow of this 
Society, his name has been so frequently of 
late years mentioned in our abstracts that it is 
only right that we should express our regret at 
the death of this distinguished embryologist 
at the early age of 43. Ryder began to make 
himself known to biologists when he was 
embryologist to the United States Fish Com- 
mission. In 1886 he became Professor of 
Comparative Embryology at the University of 
Pennsylvania. The origin of sex, heredity and 
variation, the evolution of the skeleton, and 
special subjects, as dynamics in evolution, and 
the mechanical genesis of the scales of fishes, 
were some of the many subjects on which he 
laboured, and on which he published results of 
great importance.

Apparatus for Drawing off 10 ccm. of Nu- 
trient Medium. \ — The apparatus devised by Dr. 
K. Knauss for removing 10 ccm. of gelatin or 
bouillon is a cylindrical funnel (fig. 95). The 
upper part of the outflow tube is closed by a 
ground glass rod which projects some few cm. 
above the top of the funnel, ending in a sort of round handle. . The 
cylindrical part of the funnel is graduated in 10 ccm.’s from 10-60 ccm.
