The severe functional disturbances of sunstroke are not adequately accounted for by the morbid anatomical changes so far described in this condition. Edema, hemorrhages of various kinds and extent, and venous hyperemia are the principal gross findings. Most of the histologic examinations have been made by means of the older technical methods. Obviously there is room here for experimental work, and Scagliosi,1 of Palermo, exposed guinea-pigs to the immediate action of the sun's rays during the months of August and September, when the highest temperature varied from 29.6 C. to 31.3 C. Under these circumstances the animals, as a rule, succumb in from 1 to 3 or 4 hours after great rise in temperature, hurried respiration, rapid heart's action and convulsions. Animals in the state of prostration when brought into a cool atmosphere revive temporarily but die later with continued fall of the bodily temperature. Careful postmortems were now
