As to theposi hcemorrhagic leucocytosis , Huhnerfauth found that 

 nine dogs which had lost onerfourth of their weight by acute 

 haemorrhage, showed on the same day a hypo-leucocytosis but the 

 white cells had greatly encreased the following day (maximum 45,- 

 000) and considerable encrease persisted for three or four weeks, 

 lyion and Rieder had similar experimental results (with a maxi- 

 mum of 62,000), with only one exception. Considering the im- 

 portant r61e taken by leucocytes in phagocytosis, these suggest a 

 measure of support for the now all but discarded phlebotomy in 

 severe inflammations in strong, vigorous systems. 



Eosinophilia is found to be a very marked phenomenon in 

 connection with the anaemia of certain parasitisms, as uncinaria, 

 trichina, bothriocephali, taeniae, strongyli, sclerostomata, ascar- 

 ides, etc., so that it has been supposed that the production of the 

 eosinophiles, is stimulated by toxins which the parasites have 

 generated. In cachectic conditions and suspected parasitism, 

 therefore, a count of these cells may corroborate the conclusion, 

 or otherwise. 



In case of double ringbones with severe lameness and other 

 indications of constitutional bone disease, Moore, Haring and 

 Cady found the eosinophiles in as great excess as in helminthi- 

 asis. The presence of worms is not specifically excluded, but if 

 they were, this might introduce another line in which blood counts 

 might prove useful.
