General Symptoms 



Except in those cases where the disease is ushered 

 in by the ordinary symptoms of acute lymphangitis, 

 there are very seldom any systemic changes accompany- 

 ing the disease, at least in its early stages, nor for weeks 

 or months after it has developed. The temperature 

 generally remains normal, but in some cases there may 

 be an inclination to very slight intermittent fever, 

 which seldom runs above 102°, and only recurs about 

 every ten days. The appetite is seldom or never 

 impaired, and except in very advanced cases, which 

 tend to become generalized, there is no loss of con- 

 dition ; in fact, the disease seems to thrive best 

 on animals in good condition in which the lymphatics 

 are well developed and in good working order ; 

 however, in deference to the foregoing symptoms, 

 and those usually described, I have to state that I 

 have seen the disease, in at least one verified case, 

 rapidly develop and run a very acute course, in 

 which the whole system was effected. The case 

 from which Plates No. XIV, XV, and XVI were 

 obtained is the one in point. The subject was a five- 

 year-old Arab trooper, admitted into hospital with 

 simple fever, temperature 103*4. ^'"^ ^^^ course of a 

 few days symptoms of purpura haemorrhagica began to 

 develop, the nose and extremities became oedematous, 

 and the temperature continued to vary from 103 to 

 104. The pulse was accelerated, the mucous mem- 

 branes were injected and presented a few petechiae, and 

 the appetite was impaired. The case was treated for 

 purpura, but in the course of about three weeks ulcera- 

 tions were detected on the pituitary membrane, and 

 simultaneous with these symptoms a profuse discharge 

 from both nostrils developed, marked enlargement of
