iurbance of the function of the thyroid gland. The author has attempted t» 

 treat the condition in horses through the administration of dried and powdered 

 thyroid gland. Of 15 horses treated two are said to have been cured and four 

 recognizably improved. Of the nine horses in which treatment failed four art 

 said to have been very old. 



Parasites and parasitic diseases of the dog and cat, L. G. Neumann {Para- 

 sites et Maladies Parasitaires du C'hien ct du Chat. Paris, 1914, PP- J+3^8, 

 figs. 156). — The several chapters of this work deal with parasites of the skin, 

 connective tissue and muscles, digestive .system, serous membranes, respiratory 

 system, circulatory system, brain and organs of sense, and geni to-urinary 

 organs. 



Brief mention of parasites of the ferret is made in an appendix (pp. 337-340). 

 A subject index is included. 



Investigations of spirochetosis of fowls from Tunis and of Argas persicus, 

 'Which transmits the disease. III, B. Galli-Valebio {CcntN. Bakt. [etc.], 1. 

 Abt., Orifj., 72 (1914), Xo. 6-7, pp. 526-528).— In this third memoir (E. S. R., 

 20, p. 1154; 22, p. 392) the author reports finding A. persieus which became 

 infected with Spirochwta anserina to be free therefrom in from nine to ten 

 months. A. persicus from Humt-Suk, island of Jerba, caused a fatal chronie 

 disease in fowls six months after arrival at Lausanne. This tick is very re- 

 sistant to high and low temperatures and can survive without food for 21 

 months. 



The blood of the fowl in experimental spirochetosis, L. Launoy and M. L. 

 Bruhl (Ann. Inst. Pasteur, 28 {1914), ^o. 5, pp. 517-539, pi. 1, figs. 6). — The 

 infection of the adult fowl with Spirocho'ta gallinarum causes a rapid and 

 marked anemia in which the erythrocytes are reduced in number by one-half 

 in five days. 



Investigations in regard to the blood cells of healthy and sick fowls and 

 pigeons, E. IIedfeld {Ahs. in Deut. Ticrdrztl. Wchnschr., 21 {1913), No. 17, 

 pp. 266, 267). — The following kinds of white blood cells were noted: Eosinophil 

 leucocytes vfith rod-like granulations, eosinophil leucocytes with grain-like 

 granulations, large lymphocytes, small lymphocyte.s, and basophil leucocytes. 

 The blood was taken from a wing vein. It was noted that in the birds hema- 

 toblasts occur, but the amount is greater under pathologic conditions. Neutro- 

 phil cells were never noted. 



The absolute number of blood cells per cubic millimeter for erythrocytes was 

 4.000,000 and for leucocytes 24,000. The differential leucocyte count was as 

 follows : Eosinophils with grain-like granulations, 2G to 30 per cent ; eosino- 

 phils with rod-like granulations, 10 to 20 ; large lymphocytes, 12 to 13 ; small 

 lymphocytes, 42 to 49 ; and basophil cells, 3 per cent. By treating the birds 

 with either fowl cholera or erysipelas cultures the following blood picture was 

 noted : Hypoleucocytosis followed by a hyperleucocytosis which went up to 

 101,000, and a rise in eosinophils up to 74 per cent. The birds were also fed 

 with the heart muscle of a goose which died from fowl cholera. After infesta- 

 tion with round worms {Ascaris megalocephala and A. suis) the number of 

 "White cells was 125,000 and the eosinophils 74 per cent.
