Those experiments suffice to show that in animals heating the body artificially 

 ppuliices disturbances of circulation and of innervation similar to lliose present in 

 ordinary fever. In man the ])henomena of sunstroke, or, as I prefer to call it, thcnnic 

 ffvrr, show that expusiive to external beat may ]>r()dtice all the symjilonis of tlie 

 febrile stati-. Tlic foiluwiii<; description of the symptoms present in that disorder, 

 given by Dr. Boiniyman (Kdinhunjh Mai. Joiirtud, l^(54), shows how precisely th«y 

 agree witli those of ordinary severe fe\(r. 



" Wlierc premonitory symptoms show themselves, they are sometimes well 

 marked. Tiiose nsnally observed arc — inaptitude and disinclination for any exer- 

 tion, drow.'^iiiess, or a desire to sleep, vertigo, headache, and slight confusion o( 

 ideas ; the patient feels weak, sighing frequently ; the appetite is gone, thirst is 

 increased, and the bowels arc constipated ; the symptoms become aggravated, and 

 the patient either jiasses into the state of profound coma, or symptoms of the first 

 or progressive form of the malady arc comidained of, viz , distressing headarhe, 

 with a feeling of weight and heat in the occiput, tightness, distention, and throbbing 

 in tlic forehead and temples, anxiety at the prfccordia, nausea, and a disposition to 

 vomit. A sensation of sinking or of insupportable wei;;ht, or uneasiness, is referred 

 to the pit of the stomach, and a feeling of horror or of impending calamity, with a 

 terulency to weep, is expf-rienced. The breathing is natural, or slow and sighing. 

 The face is generally natural or somewhat flushed, eyes bright, ]>upils either natural 

 or somewhat contracted. The skin is very hot and dry ; tli(> pulse is ftdl and 

 accelerated, tongue white, thirst intense, bowels confined, the nrinc su])press(Ml. If 

 tliese symptoms persist, tetanic convidsions suddenly appear, and the patient lapses 

 into the wcond or severe form of the disease." 



After tieath from tinrmic fever the condition of the blood so closely resembles 

 that seen after a malignant fever as to have caused various skillful physicians to
