484 SPORADIC DISEASES. 



symptoms when at rest, are seized with trembling when made 

 to undergo the slightest exertion, assume a very haggard appear- 

 ance, drag their limbs slowly and stiffly, and after a drive of 

 four or five miles will often suddenly drop down dead. 



" The prostration is even more marked in sheep, and in very 

 many cases they seem to be quite unequal to the task of rising. 



" In vomiting animals, emesis is a prominent symptom. 

 Calves tremble while sucking, and often stop suddenly, eject 

 tlie contents of their stomachs, fall to the ground, and perish. 

 In pigs and dogs, vomiting and constipation are prominent 

 symptoms ; swine burrow under their litter, and are roused with 

 difficulty, and dogs get ' the slows,' and are unable to follow 

 their master. The result of exertion is the same in all. 



" ' Convalescence in this disease is as peculiar as any other 

 feature in its clinical history ; and to this peculiarity I would 

 invite especial attention, inasmuch as these facts are important 

 in the study of its special pathology. Convalescence is rarely 

 marked by a critical evacuation of any kind. I have no recol- 

 lection, in any case, of a critical perspiration to mark the 

 initiation of convalescence. A moist skin during the active 

 stage of this disease, in my opinion, never occurs. Diuresis, or 

 diarrhoea, as a rule, does not occur as a critical discharge. It 

 is true a resumption of these functions occurs, but not in quan- 

 tities to be regarded as critical. I have occasionally seen 

 diarrhoea occur as a sequel, with typhoid symptoms ; but I 

 have always regarded it as a result of injuries inflicted by the 

 injudicious use of drastic purgatives, or as an evidence of 

 urtemic poisoning from retained excreta. Ordinarily, convales- 

 cence is marked by a cessation of the characteristic symptoms, 

 and a gradual resumption of the impaired and suspended 

 functions, — only this and nothing more. There is a popular 

 belief that a patient once suffering from this disease never fully 

 recovers ; and that, upon exposure to heat and fatigue, he is 

 liable to a relapse. This, it is true, does occur occasionally, but 

 not as a rule. On the contrary, I could point to scores of cases 

 where recovery has been perfect and complete.' — (Dr. Phillips.) 



" Mr. Beardsley also testifies to the permanency of the effects, 

 and liability to relapse in many cases.
