lips ; neck long, thin ; anterior segments parallelepipeds, the 

 median very long, the posterior almost square, the terminal 

 rounded ; length of head, 3 mm.; breadth, i mm. ; length of the 

 median rings, 9 mm.; of the posterior, 4 mm.; total length, 

 I metre 60 centimetres" (3 feet 23 inches). As no one has 

 noticed that the worm was specially injurious it need not be 

 further noticed. 



Ascaris Mystax. Ascaris Marginata. This presents all 

 the characters of the ascaris of the dog, of which it is considered 

 to be a smaller variety. The male is 4 to 6 cm. and the female 

 4 to 10 cm. It is found especially in the stomach and intestine 

 of young cats, but may be in those of any age. Krabbe found it 

 in 50 per cent, of all cats examined and in numbers varying from 

 I to 80. Unless numerous it does not seriously affect the health, 

 but if abundant they cause nausea, vomiting, capricious appetite, 

 indigestion, diarrhoea, emaciation and loss of weight. 



The best treatment is usually by areca nut, 5 to 10 grains daily. 



Oxyuris Compar. Female worms 8 to 15 mm. long were 

 found by I,eidy in the small intestine of a cat at Philadelphia. 



Uncinaria Trigonocephala. Dochmius Balsami. Rail- 

 liet has demonstrated the identity of this worm with that causing 

 pernicious anaemia in the dog. 



Habitat. The duodenum of the cat, the worms being firmly 

 attached by their hooks to the mucous membrane. 



UNCINARIOSIS IN CATS. PERNICIOUS ANEMIA. 



Symptoms. These vary with the number of worms. One or 

 two may do no appreciable harm, while if the embryos are con- 

 stantly taken in in the water a progressive weakness and de- 

 bility are rapidly developed. About the first symptom is loss of 

 weight and encreasing emaciation. The plump roundness, and 

 lithe activity give place to a soft flaccid condition, dulness and 

 indisposition to exertion. Then there are irregular or capricious 

 appetite, vomiting, diarrhcea, soiling of the tail, pallor of the 

 sunken eyes and mouth, and gradually encreasing debility. In 

 the worst cases death may occur in a month, in others there are 

 alternate improvement and aggravation, while in some a complete 

 recovery may be made. 



The diagnosis is based on the gradually advancing character of
