(Pentastoma temoides), which, as already stated, fs the 
adult representative of the Pentastoma denticulatum, tc- 
siding in the viscera of the horse, as well as in the internal 
organs of ruminants. (Fig. 31.) The illustration is from 
Kiichenmeister. 
“In the full-grown state this creature dwells in the nasal 
and frontal sinuses, our dogs commonly obtaining the worm 
by frequenting butchers’ stalls and slaughter-houses, where 
portions of the fresh viscera are apt to be inconsiderately 
flung to hungry animals.” 
Professor Dick records a case of suspected poisoning in 
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 lett 
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 
migration of the pentastomes, thereby also producing the 
fatal suffocation.” 
Respecting what Dr. Cobbold terms the “misnamed 
maw-worms,” so frequently seen on the feces of dogs, “ they 
are,” he remarks, “ merely the semi-independent segments, 
or proglottides of two of the larger species of tapeworm 
which infest the dog, namely, 7@uia marginata and Tenia 
serrata. 
“Jt 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. 
“T may add, that when santonine is employed for any 
of the round worms, it should always be combined with a 
purgative, if it is to prove effective. For this purpose 
nothing is ordinarily better than castor-oil ; but 20 or 30 
grains of aloes may be employed instead of the oil in
