The cui'd is then brought to 86°, with constant stirring, and allowed to settle 

 for 30 minutes. It should then be firm and spongy and should readily sink to 

 the bottom of the vat. When these conditions are obtained the whey should 

 be poured off and the curd tied in cheesecloth and drained on a rack for about 

 li hours, the curd mass being cut into 4-in. cubes three or four times to facili- 

 tate drainage. 



The curd is next broken up by hand and salt added at the rate of 1 oz. to 

 3 lbs. of curd. After a thorough stirring the curd is again inclosed in cheese- 

 cloth and weighted in molds. After being pressed overnight the cheese is 

 trimmed, bandaged in clean calico, again pressed for 2 hours, removed from the 

 mold, placed in the making room, and turned daily for 2 or 3 days. It is then 

 removed to a shelf in a cooling room and tui'ned daily. The cheese is ready 

 for use in from 3 to 5 weeks, and should keep in good condition for from 8 to 

 10 weeks. The yield is said to be about 3 lbs. of cheese for each 4 gal. of skim 

 milk.

The meat inspection service of the United States Department of Agricul- 

 ture, G. DiTEWiG (U. S. Dept. Agr. Yearbook 1916, pp. 77-97, pis. 11, figs. 5).— 

 This is a description of the manner in which the Federal meat inspection is 

 carried out under the regulations previously noted (E. S. R., 32, p. 777). 



Report of State veterinarian and State live stock sanitary board for 

 1914 and 1915, C. J. Marshall {Ann. Rpt. Penn. Dept. Agr., 21 {1915), pp. 89- 

 173). — This report deals with the occurrence of and work with transmissible 

 diseases of live stock in Pennsylvania, and includes an account of control work 

 with foot-and-mouth disease, hog cholera, rabies, tuberculosis, etc. 



Report of proceedings under the diseases of animals acts, with returns of 

 the exports and imports of animals, for the year 1915, D. S. Prentice {Dept. 

 Agr. and Tech. Instr. Ireland, Rpt. Diseases Anim., 1915, pp. 34). — This is the 

 usual report (E. S. R., 35, p. 279) dealing with the occurrence of infectious dis- 

 eases of animals, and including statistical data. 



A further note on the life history of Gongylonema scutatum, B. H. Ransom 

 and M. C. Hall {Joiir. Parasitology, 3 {1917), No. 4, pp. 177-181).— The ques- 

 tioning by Seurat, as previously noted (E. S. R., 37, p. 361) and elsewhere,' of 

 the identity of the species studied by the authors (E. S. R., 34, p. 783) has 

 led to the further work here reported. 



The authors have definitely proved that dung beetles and croton bugs fed 

 upon the eggs of O. scutatum become infested with an encysted larval stage of 

 the parasite. The evidence is also very strong, if not quite conclusive, that 

 sheep, cattle, and other suitable mammalian hosts become infested as a result 

 of swallowing infested insects which usually under natural conditions are 

 various species of dung beetles. 



" The nematodes found in several species of Blaps in Algeria and identified 

 by Seurat as the larvae of G. scutatum belong to some other species. It is not 

 improbable that the nematodes found in Algerian beetles, which Seurat has 

 considered to be the larvae of G. mucronatum in reality belong to G. sciitatum."

 the Japanese and European strains, H. Noguchi {Jour. Expt. Med., 25 {1917), 

 No. 5, pp. 755-763). — " Wild rats captured in this country carry in their kidneys
