Diseases of Domestic Animals, xxxik 



ject ; but of our stock being liable as well to the common dis- 

 eases to which they are from their nature exposed in all 

 countries, as to peculiarly fatal diseases, the origin of which 

 is involved in great obscurity. 



In the states of South Carolina and Georgia, cattle hrought 

 from Euroi>e, or from the interior, to the vicinity of the sea, 

 are invariably attacked by a disease which is generally fatal. 

 Cattle from the interior of the state of South Carolina, (but 

 only a particular district,) so certainly disease all others with 

 w hich they mix in their progress to the north, that I am told 

 they are prohibited by the people of Tirginia from passing 

 through the state. A singular fact attending the disease is, 

 that the cattle alluded to, have the power of infecting others 

 with which they associate, while they themselves are in 

 perfect health ;5i this I can assert from my own personal ob- 

 servation, in the year 1796. The particulars of this singular 

 but fatal complaint I shall hereafter detail. Pennsylvania 

 has to re.2;ret the loss of many thousand horses, by a disease 

 which deserves no other name than yellow fever. I allude 

 to the *< ijellow water,'^ the symptoms and method of cure 

 of which are totally different from the jaundice, yellows, or 

 yellow water of Europe. This disease, I have reason to be- 

 lieve, is peculiar to North America.^^ 



Europe furnishes no disease similar to the mortification 

 in the limbs of the New England cattle ;53 nor to that peculi- 

 ar salivation which has Avithin the last twenty years attack- 

 ed our horses, from eating second crop grass, particularly 

 red elover,^^ and which from its debilitating effects, amounts 

 to a disease. For the last four or five months, a new and 

 very fatal disease has prevailed among the horses in the vi- 

 cinity of New Brunswick, New Jersey. 



4. It has already been shown, that by means of compara- 

 tive anatomy we have ascertained the uses of various organs 

 of the human body ; and I now can add, that by an attention 

 to the diseases of brute animals, the following advantages 

 have also resulted to mankind.
