Flies collected included the Miiscids, Musca domestica, Calli- 

 phora erythrocephala, Lucilia caesar and the Anthomyiids, Fannia 

 canicularis and Hydrotaea dentipes. In experiments against these 

 flies good results were obtained with formalin vapour — 20 cc. of 40 

 per cent, formaldehyde, 8 grm. potassium permanganate (powdered) 

 for each 1,000 cu. ft. — and fonnaUn in solution — 10 parts of 40 

 per cent, formaldehyde, 50 lime water, 2 sugar, and water up to 100. 

 Of the various substances added to a solution of treacle and water 

 the folloN^ing killed all flies in from 24 to 48 hours : sodium arsenite, 

 10 per cent. ; sodium iodate, 2 to 5 per cent. ; sodium fluoride about 

 2 to 5 per cent. ; ammonium fluoride, 10 per cent. ; potassium iodate 

 about 2 to 5 per cent. ; and copper acetate about 2 to 5 per cent. 

 Beta-naphthalene was apparently useless. Formalin solution is con- 

 sidered to be the best for indoor use, and sodium arsenite for manure 

 heaps, etc., for which purpose ammonium fluoride is also suitable 

 and less poisonous.

 Med. Vet., Brussels, Ixvii, no. 1, January 1922, pp. 19-22. 



The symptoms and treatment of piroplasmosis of dogs due to 

 Piroplasma canis are described. In France the disease is trans- 

 mitted by Dermacentor reticulatus and probably also by Rhipicephalus 

 sanguineus. The disease generally appears after a day's hunting, 

 chiefly in the autumn and winter, and, in the neighbourhood of Paris, 

 especially during September and April.
