ABSTRACT OF PROCEEDINGS. Xlll, 
Abstract of lecture on ‘“‘The Blood in Health and 
Disease,”’ by J. F. FLASHMAN, M.D., Ch.m., delivered 18th June, 
1908.—The lecturer showed the physical constitution of 
the blood of various animals, as distinguished from that of 
man, pointing out the limitations of this method of investi- 
gation as a means of distinguishing human from other forms 
of mammalian blood. Illustrations were given of the 
various varieties of white cells, or leucocytes, and the 
phenomenon of phagocytosis was described, and the effect 
of the phagocytes as protectors against disease was dwelt 
upon. Clotting of blood was discussed, and it was shown 
that blood could be prevented from clotting if the lime 
salts of the blood were removed. The changes in the blood 
in such conditions as anemia, pernicious aneemia, etc., 
were illustrated, and a general review given of those blood 
diseases—such as malaria and sleeping sickness—due to 
parasites. Attention was called to some interesting bio- 
chemical relations of the blood, such as agglutination in 
typhoid fever, bacteriolysis, antitoxin production; the 
test for human blood by means of the precipitin reaction 
was described, as was also our present knowledge of 
opsonins. The method by which the information placed at 
our disposal by the discovery of opsonins was utilised in 
the treatment of disease, was demonstrated. The lecture 
was illustrated) by lantern slides and microscopic pro- 
jections, as well as: by exhibits and demonstrations.
