The Council for 1888-9 consists of S. W. Mitchell, President; 
H. N. Martin, Secretary and Treasurer; H. P. Bowditch, J. G. 
Curtis, H. C. Wood. 
Dr. S. Vv^eir Mitchell placed at the disposal of the Society 
the sum of two hundred dollars to be offered as a prize for re- 
searches on the rate of transmission of nerve impulses in man, 
such researches to be completed at the end of two years. 
Physiological Prize. — In accordance with the offer of 
Dr. S. Weir Mitchell to the American Physiological Society, 
the latter Society now formally offers to residents of North 
America the prize of two hundred dollars for researches bear- 
ing on '•'the rate of transmission of nerve impulses — afferent 
and efferent — and the duration of reflex and reaction time in 
the higher animals, especially man ; also the conditions — nor- 
mal and pathological — which alter such rates and times." The 
work must be done between Jan. i, 1889 and Oct. i, 1890. 
Further information may be obtained of Prof. H. Newell 
Martin, Baltimore, Maryland : Johns Hopkins University. 
Proposed International Congress of Physiologists 
IN 1889.— In accordance with the circular issued by the Eng- 
lish Physiological Society, a meeting was held in Berne, Swit- 
zerland, in September, 1888, to consider the advisability of 
holding, during the present year, an international congress 
of physiologists. England, France, Germany, Italy and Swit- 
zerland were represented. It was decided to hold such a 
congress at Basle, beginning September 10, 1889. The sub- 
jects to be brought before the meetings include Anatomy, His- 
tology. Physics, Chemistry, Experimental Pathology, and 
Pharmacology, in so far as they bear directly upon Physiology. 
All communications are to be as little formal and as fully de- 
monstrative and experimental as possible. Professor Miescher 
and the Department of Education of the City of Basle have 
cordially approved the project. The committee of the English 
Physiological Society has been continued with executive powers 
to organize the Congress, and through a circular requests in- 
formation concerning probable attendance, titles of intended 
communications, and details of apparatus required for demon- 
strations. American physiologists intending to be present 
may notify Dr. H. P. Bowditch (till July ist),"^ Harvard Medi- 
cal School, Boston, Mass ; (subsequently) care of Knautt, Na- 
chod & Kuhne, Leipzig, Germany.
