read. And since from its originality, and excellence, I have no 

 doubt it will go through another edition, I am induced to hope you 

 will, in a future edition, say something on a preventive of distemper 

 in dogs, which has been lately tried, if after a trial you should Jind 

 it to answer. About two years ago, when in Sussex, I had frequently 

 heard at table, that inoculating a dog with the cow-pox virus would 

 prevent it from having the distemper. About half a year after- 

 wards, having a pointer puppy, a few months old, I inoculated it. 

 The dog has never had the distemper yet ; but since dogs sometimes 

 escape this cruel disease till old age, and sometimes entirely, this can 

 be no proof. However, you may possibly deem the supposed pre- 

 ventive worth a trial ; and, as no one is a greater friend of the dog 

 than I am, it would afford me the sincerest pleasure if you should find 

 it succeed, and make it known. After reading your publication, Sir, 

 no one can doubt of your being a sportsman, and as such you must 

 feel an affection for your faithful companions in the field; and since 

 this will plead for me, and I shall ask your bookseller whether he 

 cannot make this reach you without putting you to the unnecessary 

 expense of postage, I shall make no further apology. But I am, Sir, 

 " Most respectfully, 



" Your obedient humble servant, 

 " London, October, 1816. ' CANIS AMICUS. 



" P. S. I should observe, the part where I inoculated my dog 

 was on the inside of the foreleg, under the shoulder. It was done 

 by cutting a very small place with a pair of scissors, and rubbing the 

 bone, or quill, charged with the virus, into the wound. From the 

 appearance of the wound, a few days after, I was afraid the virus 

 had not taken effect, but I have been told that this slight appearance 

 is usual.
