satisfaction for complying with these proposals as the lords justices shall 

 think fit. 



The 4 justices received orders to comply with the preceding proposals, and to 

 allow 40 shillings for every sick cow which they burnt, belonging to Mr. 

 Ratcliffj Rufford, and Pullen. But the free intercourse, which both masters 

 and servants had had with each other's cows, had spread the contagion; and 

 the distemper began soon to appear in several other neighbouring places. 



The gentlemen then summoned all the cow-keepers in the county, and 



acquainted them with the above-mentioned proposals, and offered them 40 



-shillings for every cow they burnt, that had not been sick above 24 hours ; but 



for such as had been longer ill, or were dead, they would allow them only the 



value of their skins and horns. 



On dissecting l6 cows, in different degrees of infection, I found the putre- 

 faction of their viscera to increase in proportion to the time of their illness. The 

 first 5 that I opened, had herded with those that were ill, and the symptoms of 

 the distemper were just become visible ; in these, the gall-bladders were larger 

 than usual, and filled with bile of a natural taste and smell, but of a greener 

 colour. The pancreas was shrivelled, some of the glands were obstructed, and 

 tumefied. Many of the glands in their mesenteries were twice or thrice their 

 natural size. Their lungs were a little inflamed, and their flesh felt hot. All 

 other parts of their viscera appeared as in a healthful state. 



The next 6 that I opened, had been ill about 2 days. In them the livers 

 were blacker than usual, and in two of them, there were several cysts filled 

 with a petrified substance like chalk, about the size of a pea. Their gall- 

 bladders were twice their usual size, and filled with bile of a natural taste and 

 smell, but of a greener colour than the first. The pancreas was shrivelled, some 

 of the glands were very large and hard, and of a blackish colour. The glands 

 in their mesenteries were many of them 5 times their natural size, and of a 

 blackish colour. Their lungs were inflamed, with several small cysts forming. 

 Their intestines were full of red and black spots. Their flesh was very hot, 

 though not altered in colour. 



The 5 last that I opened, were very near dying. In them I found the liver 

 to be blackish, much shrivelled and contracted, and in 3 of them, there were 

 several cysts as large as nuts or nutmegs, filled with a petrified substance like 

 chalk. Their gall-bladders were about 3 times their usual size, and filled with 

 bile of a natural taste and smell, but of a deep green colour. The pancreas 

 was shrivelled and contracted, many of the glands were very large and hard, and 

 of a black colour. The glands in their mesenteries were many of them
