256 THE MICROSCOPE IN VETERINARY MEDICINE. 
the metatarsal bones were selected for microscopical exami¬ 
nation. In the first, the cancellated structure was abnor¬ 
mally abundant, and so far encroached upon the shell of the 
bone that it was reduced to an exceedingly thin plate; the 
structure, however, was healthy. The more dense metatarsal 
bones presented a very peculiar appearance, a transverse 
section showing the Haversian canals in various unusual 
formas. In some parts of the bone they were merely dilated ; 
in other places they were elongated, giving to the object the 
aspect of an oblique or longitudinal section, and in places it 
appeared as if several of the canals had become connected by 
the obliteration of their walls, forming considerable cavities. 
Some of the canals remained healthy. In the dilated canals 
a quantity of yellow granular fat was observed. All these 
appearances are depicted in the accompanying illustration.
