2 1 8 Veterinary Medicine. 



Symtoms Caused by the Larvae. As a rule these pass en- 

 tirely unnoticed. If very numerous, troubles may follow varying 

 with the organ invaded ; emaciation from infested mesenteric 

 glands, icterus or intestinal disorder from the liver ; cough from 

 the lungs. Usually a slight lack of condition, only, is seen in the 

 affected animals, but in no case is there any hope of a certain 

 diagnosis during life. 



Prevention. This must aim at interrupting the normal cycle 

 of development of the parasite. In localities where this exists 

 dogs should be denied access to all raw offal of sheep or other her- 

 bivora. The waste product of abbatoirs must be sterilized by heat, 

 and the heads and carcases of dead sheep, etc., must be treated in 

 the same way. 



Dogs affected with paroxysmal, dry sneezing must be treated, 

 and, as far as pos-sible, all dogs should be excluded from sheep 

 pastures. 



Other IyInguatuiT^. Railliet records the following instances 

 of infestment by other linguatulse : Linguatula Recurvata in the 

 frontal sinus and trachea of a jaguar in Brazil ; Linguatula Sub- 

 triquetra in the throat of an Alligator ; Pentastomum Momliforme 

 in the lungs of a striped python and in the liver and other viscera 

 of dogs, lions and panther ; Pentastomum Proboscideum, and P. 

 Subcylindricum in the lungs of American reptiles and mammals ; 

 Pentastomum Constrictum in the lungs, etc. , of negroes and 

 giraffe in Egypt, and in soldiers, causing fatal pneumonia and 

 peritonitis. It is, therefore, not improbable that opportunity only 

 is lacking to make these parasites of domestic animals. 



SCORPIONS. 



Scorpions look dangerous by reason of their formidable crab- 

 like pincer claws, but these are comparatively harmless. The 

 real danger lies in the venomous sting in the end of the tail but 

 even this is not serious except in the case of some large tropical 

 species (nine or ten inches long) and when used on small animals. 

 On the larger it may cause a local inflammation but no more. 

 In Europe Maupertius found that dogs and chickens suffered only 

 temporary inconvenience from the sting, while in Redi's hands it
