 culty generally experienced in vaginal taxis — which is, after all, the 

 most reasonable, least dangerous, and perhaps the most convenient of 

 all methods — several devices have been brought forward to render it 

 more easy and effective. Of these none deserves more notice than that 

 of Darreau, which was brought before the Central Veterinary Medical
