 is rather less marked on the under than on the upper surface. No evidence 

 of haemorrhage into the substance of the brain upon section. Heart, 

 apparently nothing unusual; coronary arteries apparently not congested. 

 No haemorrhagic areas in the wall or upon the internal surface of the 

 left ventricle. Lungs, acutely congested. 



Abdominal organs. Liver, omentwm, and mesentery apparently acutely 

 congested. Spleen and kidneys slightly, if at all, congested. Intestine, not 

 opened. 



EXPERIMENTS WITH SIX RABBITS IN THE SUN AND IN THE SHADE, AT 



BAGUIO. 



Since the black or dark-gray-haired monkeys succumbed so 

 easily to the sunlight, it was determined to employ rabbits having 

 the widest possible range of fur pigmentation. For this purpose 

 6 rabbits, 2 pure white, 2 gray, and 2 black were shipped to me 

 from Manila.
