Rickets. 



A LIFE of art appears to subject many of the smaller races 

 of dog-s to the same deficiency of earthy matter in their bones 

 as is witnessed in the human infant, and puppies are often 

 born ricketty, or become so as soon as they begin to walk. 

 Pugs, and the smaller terriers, are very liable to it. There 

 is likewise a breed of larger terriers, in which the deformity 

 is hereditary, and is cultivated ; these are called wry legged, 

 and are used for hunting rabbits, &c. &c. The affection at- 

 tacks all the joints of the extremities, which it enlarges, 

 probably from a sympathy in the constitution to make up, by 

 bulk, what the bones want in ponderosity, but which is not 

 effected ; for, deprived of their earth, they yield to the su- 

 perincumbent weight, and the cylindrical ones particularly 

 become crooked. Cleanliness, good air, free exercise, and 

 wholesome food, will commonly prevent it in the future 

 breeds of such dogs as have shewn a disposition to it. As a 

 cure, an invigorating diet added to these, with the occasional 

 use of tonic bitters if the appetite fails, or the digestion should 

 appear defective, will answer the intention.

Scirihus, 



In the human subject this is considered as the primary 

 stage of cancer ; but dogs, though very subject to scirrhus, 

 are but little liable to cancer. It is true these scirrhous tu- 

 mours very frequently ulcerate, and such ulceration proves 

 obstinate, and spreads; but it reaches only through the ex- 

 tent of the gland, and very seldom attacks the surrounding
