 Previous investigations on the subject are first reviewed, tlie temperature of 

 different birds as reported by different investigators being given in tabular 

 form. 



The author's investigations were hirgely devoted to a study of the rectal 

 temperature of fowls, the results of which are reported in tabular form. The 

 factors considered include the influence on body temperature of age in the 

 domestic fowl, turkey, guinea fowl, pigeon, pheasant, goose, and duck (E. S. R., 

 22, p. 72) ; of sex in the domestic fowl, turkey, pheasant, goose, and duck; of 

 breed in the domestic fowl, turkey, and pheasant ; of molting in the hen ; and 

 of food in the goose. The influence of setting and of the surrounding tempera- 

 ture are briefly considered, while the daily variation and the influence of hunger 

 and thirst and of digestion are shown by means of charts. The temperature 

 of 72 species, representing 31 families of exotic birds at the zoological gardens 

 in Halle and Le4psic, is also reported. 



The respiration of 90 hens observed varied in frequency from from 12 to 28 

 per minute with an average of 1S.44 ; of 40 turkeys from 12 to 16 with an 

 average of 13.4 ; of 90 pigeons from 16 to 86 with an average of 25.51 ; of 40 

 geese from 12 to 20 with an average of 13.10 ; and of 90 ducks from 16 to 28 

 with an average of 18.84. « 



The body temperature of fowls, F. Loee {Dcut. TierdvzU. Wchnschr., 11 

 {1909), Xo. J,l, pp. 698-100, charts -', ; uhs. in Rec. Med. Vet., 86 {1909), No. 23, 

 pp. 8Jf3, S '/'/)• — The temperature readings of numerous individuals of different 

 breeds of the domestic fowl, as summarized In the account above noted, are 

 here reported in tabular form, accompanied by charts. 



Diseases of fowls, G. Bradshaw {Dept. Agr. N. 8. Wales, Farmers' BuJ. 15, 

 pp. 101, pis. 2, figs. IS). — A second edition of this general account of diseases of 

 fowls to which several additional disea.ses, notably infectious enteritis, which is 

 said to have had deva.stating effects on several of the large poultry fax'ms, have 

 been added. 



Fowl plague is not a contagious disease, E. ^Iarchoux {Compt. Rend. Soc. 

 Biol. [Paris], 68 {1910), No. 8, pp. 3Ji6, 341)- — The author's experiments appear 

 to .show that fowl plague is not conveyed through the feces. He considers it 

 probable that the transmission takes place through some acarid other than 

 the fowl tick. 



A new lucocytozoon of the fowl, C. Mathis and M. Leger {Compt. Rend. 

 ^oc. Biol. [Paris], 68 [1910), 'So. 1, pp. 22-2-'/). — A second species of Leucocy- 

 tozoon discovered in the blood of the domestic fowl in Tonkin is here described 

 as L. sabrazesi. It was found in 5 of 439 fowls examined. This is thought 

 to be the first time that 2 species of Leucocytozoon have been recorded from 

 the same bird host. 



A study of parasitic typhlitis. The nodules of cecum parasites of the 

 pheasant, M. Letulle and Marotel (.4/c7(. Par., 12 {1909), No. 3, pp. 361-368, 

 Jigs. 2). — Nodules formed by the nematode Heteralcis vcsicularis are here 

 considered. 



The intestinal coccidiosis of young animals, J. Basset {Bid. Soc. Cent. Med. 

 Vet.. 86 [1909), No. 22, pp. .',63-Ii81, figs. 2).— A brief account of this affection 

 in the domestic fowl, pheasant, pigeon, rabbit, hare, ferret, and dog. 



The spirochetes found in the crystalline style of Tapes aureus: A study 

 in morphological variation, H. B. Fantham {Parasitology, 2 {1909), No. .'/, 

 pp. 392-'i08, pi. 1. figs. 2). — The author concludes that the spirochetes of T. 

 aureus are all referable to one species. This is probably either Spirochwta 

 balhianii, which also occurs in the oyster, or a variety of the same.
