 of the rattle- 

 snake.

3. Invariably kills birds 

 and reptiles at once in 

 convulsions. 



4. Pupil always widely 

 dilated. Salivation very 

 rarely met with. 



5. Effects on the blood 

 very great, Sanious dis- 

 charges the rule. Albumen- 

 uria is constant; After 

 recovery from the nervous 

 symptoms, the patient has 

 to go through a period 

 of blood-poisoning, perhaps 

 not less dangerous than the 

 primary symptoms. 



Dr. Wall says as regards the rattlesnake- 

 bite — " In its main features the crotalus resem- 

 bles the Indian viper in its effects, the chief 

 difference being' that the primary convulsions are 

 very much less frequently seen." Crotalus poison 

 is decidedly less dangerous than either that of 

 the Indian cobra or that of the Australian 

 hoplocephalus, and probably even than that of 

 the daboia.
