unless the whole system is entirely changed, 

 as observed by Gr^'^ory, in the Mock Doctor, 

 who says, '' The heart was formerly on the 

 '' left side, but the COLLEGE have altered 

 *' all that, and placed it on the right.'* 



To produce a case exactly similar in the 

 World of Farriehy, let us take a survey 

 of the medical abilities of Gibson, who cer- 

 tainly wrote much better on the subject than 

 Bracken ; Avhere we shall find ordered, in a 

 single prescription for a purging ball, two 

 ounces of aloes ^ w^ith the addition of the other 

 usual purging articles, though modern prac-^ 

 tice and experience fix the established pro- 

 portion at exactly half^ or at most Jive-eighths^ 

 to the strongest horses, with the cathartic 

 aids before mentioned. He also most cou* 

 rageously recommends ha/f an ounce of calo-^ 

 mely OT sublimed mercury, in a single ball ; and 

 speaks of the internal administration of most 

 powerful poisons, corrosive sublimate, or red 

 precipitate, as a matter of course : the pro- 

 portion for a dose being curiously ascertain- 

 ed by the sublime mensuration of a'' silver 

 two- pence,'' as if a premium had been ab- 

 solutely provided by an act of parliament
