 the lacrymal or tear-duct for an ulcer. This duct 

 is a continuation of the skin of the muzzle, which 

 is situated a little way up the nostril, while the 

 ulcerated tubercles are placed upon the mucous 

 membrane above the duct, and well marked by 

 a line of separation. After the formation of 

 tubercles, the animal is sure to have become con-

 down to the windpipe, and the lungs will be in
