became affected with tumours in different parts of the 

 body, which suppurated, and ran into ulcerations, and, 

 becoming quite emaciated, died in a few months. I re- 

 member another instance of a child who was to have 

 been vaccinated by a friend of mine, which was seized 

 with convulsions on the day previous to the intended 

 operation, and expired in a few hours. Now had these 

 children been inoculated, can there be a doubt, but that 

 their deaths would have been attributed by many to the 

 cowpock? and their cases have been descanted upon very 

 learnedly and at great length, by those who feel it a 

 pleasure and their interest to avail themselves of every 

 opportunity to depreciate this most beneficial practice ? 

 These occurrences should warn us against ascribing 

 effects to difterent causes than those which really pro- 

 duced them. 



" Jenner, Ring, Moreau, and many others, whose 

 experience entides them to give an opinion upon this 

 subject, confidently assert, that so far from injuring tlie 

 general health, or inducing the complaints alluded to, the 

 effects of cow pock in improving the constitution, and 

 removing several diseases, particularly those of the skin, 

 have in many instances appeared to them remarkable. 

 Mr. Simpson, in a letter to Mr. Ring, relates the case 

 of a child who was cured, by vaccination, of a most vio- 

 lent and obstinate eruption of the crusta lactea kind, 

 which covered the whole head and face, and the greater 

 part of the body, and had resisted the most active medi- 

 cines. — Several instances occurred to the same gentle- 

 man, in which the general health of weakly children was 

 much improved by it.
