 his specification of its advantages and novelty, and 

 the manner of making it appears to be as follows :

 It is further proposed to attach the shoe to the 

 horse's hoof by driving the nails obliquely, as in 

 the French manner of shoeing. With this view, 

 the nail-holes are to be punched about one-third to

 edge, and tending in a slanting direction outwards." 

 In this latter recommendation w r e cordially join the 

 colonel : he was the first writer who noticed it, and 

 is the mode of punching and nailing before alluded 

 to, and hereafter minutely described as the only 

 wise course. Since 1821 it was adopted by the 

 more intelligent smiths of the metropolis. One 

 main blunder which the colonel commits is evidently 

 intended to correct the visible insecurity of his shoe 

 at the joint: his nail-holes are punched so near his 

 patent joint as to restore the rigid immobility the 

 patent pretends to amend.

 strability of its inapplication to frogs already dis- 

 eased. But, in the hands of the professor himself, 

 and any practitioner tolerably habile in his profes-

 hands ; with these it has failed of success — in some
