EOSINOPHILIA 81 



eosins. During the early stage of oestrum she showed a moderate 

 absolute and relative eosinophilia. Two other cows examined by 

 Knight six hours and three hours after copulation had respectively 

 8,166 with 10.4% eosins and 14,846 leucocytes with 12.5% eosins. 

 The average percentage of eosins in cattle as determined by Dimock 

 and Thompson is 13.1%. In the young in man the number of 

 eosins is usually high. In four pups from less than a day to 20 

 days c'd, Burnett and Traum found the percentage of eosins rather 

 high, 11.3% in a pup less than a day old, 17.1 in one not three days 

 old, 11.8 in one not four days, 9.7 in one not six days, 5.9 in one 

 fourteen days, 6.6 in one fifteen days, and 6.6 in one twenty days 

 old. In calves, ten days to three weeks old, Knight found the 

 percentage of eosins small (1.4-1.8%). 



The eosins have been found increased in cases of helminthiasis. 

 Bucklers from observations in man states that "all varieties of 

 helminthides, from the harmless oxyurides to the pernicious 

 ankylostoma, may bring about an increase of eosinophiles in the 

 blood, often to an enormous extent." Moore, Haring and Cady 

 in horses infested with Sclerostoma equinum found an eosinophilia 

 of from 7.1 to 13.3%. 



In some cases of follicular and of sarcoptic mange in dogs and 

 cats there is usually an increase in the number of leucocytes and 

 in the number and percentage of eosinophiles. In 8 severe cases 

 of follicular mange in dogs Welch found the eosinophiles from 400 

 to 1,664 per cmm. (5 to 11%) which was an increase above the 

 normal except in one case. In four light cases he found no in- 

 crease. In six severe cases of sarcoptic mange in dogs and cats 

 there was an eosinophilia in all cases, 640-1,630 per cmm. in the 

 dog and 7,020 per cmm. in the cat. 



Welch also found an increase in the eosinophiles, 860 to 2,750 

 per cmm., in six cases of eczema in dogs. He found that the 

 eosinophilia in the cases of mange and eczema depends more 

 upon the intensity of the dermatitis, that is the amount of pruritis 

 and irritation, than upon the nature and extent of the disease. 

 In acute and chronic skin diseases in man the eosins have been 

 found increased. After the crisis in diseases having an inflam- 

 matory leucocytosis the eosins may increase to more than normal 

 numbers. Voswinkel states that they are increased in all cases of 

 severe ovarian disease excepting during the febrile stages and in
