length I discovtred a black nigged scab on the 

 cbctk of one ; and on examining it careiuily, I 

 found beneath a foul stinking ulcer, which h.id 

 eaten partly through the cheek, and was spread- 

 ing in every direction. On examining the rest of 

 the fiock, the same complaint, but in a less degree, 

 was discovered on five or six more. A corrosive 

 wash, composed of the vitriolic acid and water, 

 and another of a solution of Roman vitriol, well 

 rubbed into the very bottom of the ulcer, so as 

 completely to destroy its surface, soon sweetened 

 the discharge, and gave the ulcer a healthy appear- 

 ance : by this several were cured, but notwith- 

 standing ail the care I could bestow on them, 

 several also died. While this was doing, and 

 while at the same time I w^as rubbing one of the 

 sheep with Mr. Daubenton's remedy, {spirits of 

 turpentine a . d grease) to cure it of the scab, I 

 discovered on the back of one, several tumours, 

 about the size of a sixpence, from which the 

 wool had fallen off, and which on being pressed, 

 discharged from a very small opening, a whitish 

 matter, so thick as to retain the form of a small 

 worm. The same tumours were after this dis- 

 covered in several other sheep ; and it was these 

 which first excited a suspicion of the nature of 

 the disease. Whilst reading Laysterie's account 

 of the introduction of fine-woolled sheep into 

 Euro])c , I remarked his description of the mode 

 of procuring matter for inoculating for claveau ;.
