REPORT ON DOURINE. 



passed through a severe attack of the disease and succumbed with 

 out ever having exhibited this symptom. 



As long as an animal survive^, it is impossible to foretell 

 whether in the natural order of events any further cutane us 

 manifestations will make their appearance. After having passed 

 through the usual period of their eruption we know, however, that 

 certain methods respectively, if resorted to, may probably act as 

 exciting causes and bring about a further eruption of one or more 

 plaques. 



Of the animals which have come under our observation, in those 

 which passed through the disease and have survived up to the 

 present date, the period during which the eruption of plaques 

 persisted for, varied considerably, as may be seen in the Table, but 

 certain points may be drawn attention to in the different breeds. 



In a thorongh-bred English stallion the period was 313 days or more. 



In an Arab stallion the period was 254 to 304 days. 



In Australian mares ,, 168 to 202 



In country-bred mare* 75 to 181 



In a donkey ., 17 



From these figures it would appear that donkeys are the least 

 susceptible to the eruption of plaques, aud that country-bred mares, 

 Australian mares, Arab stallions, and thorough-bred English come 

 respectively in the order put forward. 



The following shows the period of the disease during which the 

 eruption of plaques takes place : 



Kilngarth from 67th day after covering until the 380th day interval 313 dayn.
