228 THE MANAGEMENT AND DISEASES OF THE DOG. 



the " Veterinarian " for 1840, in which he found death had 

 resulted from the presence of three of these pentastomes — 

 one in the larynx, one in the trachea, and a third in the left 

 bronchus. With regard to this case Dr. Cobbold observes : 

 " As these singular parasites appreciate warmth, I have no 

 doubt that the cold air of the winter's morning (on which the 

 dog was taken out by the keeper) caused the downward mi- 

 gration of the pentastomes, thereby also producing the fatal 

 suffocation." 



Respecting what Dr. Cobbold terms the " misnamed maw- 

 worms," so frequently seen on the faeces of dogs, " they are," 

 he remarks, " merely the semi-independent segments, or pro- 

 glottides of two of the larger species of tapeworm which 

 infest the dog, namely, Tcenia marginata and Tania serrata. 



" It follows, therefore, that the treatment for this common 

 kennel-worm is the same as that for the tapeworm, seeing that 

 it is only a cast-off portion of the self-same entozoon. 



" Areca-nut powder is the best remedy ; but male fern may 

 be sometimes substituted with advantage. 



" I may add, then when santonine is employed for any of 

 the round worms, it should always be combined with a pur- 

 gative, if it is to prove effective. For this purpose nothing is 

 ordinarily better than castor-oil ; but twenty or thirty grains 

 of aloes may be employed instead of the oil in obstinate 

 cases. In the latter case, a few grains of ginger should 

 be added, to prevent griping." 



By those interested in canine matters, and especially para- 

 sitism, I shall be excused for quoting at such length, and all 

 the more so as my quotations are taken from our most able 

 writer on the subject : a gentleman from whose works I have 

 learnt much myself, and to which with sincere pleasure I refer 

 my readers. 



With regard to the treatment of worms, various remedies 

 are advocated by different authors. I have already given the 

 treatment recommended by Dr. Cobbold 



The usual anthelmintics in canine practice are :
