YOUNG AS A PHYSICIAN. 333

 confidence of an equestrian by profession. 



In England, a physician, if he does not wish to lose 

 the confidence of the public, ought to abstain from occu- 

 pying himself with any scientific or literary research 

 which may be thought foreign to the art of curing dis-

 Sir H. Davy, he published a journal of the sciences, 

 &c. ? and moreover, we must say that his anonymous 

 disguise was not rigorously observed even in his smaller

 him forget the interests of the physician, and the name 

 of Young in large letters replaced the two small Italics 

 whose series was then terminated, and which would 

 have figured in a rather ridiculous manner in the title- 

 page of this colossal work. 



Young had not then, as a physician, either in London
