trace of sugar was found after the second or third month of ripening. The 

 acidity, expressed in terms of lactic acid, rose from 0.94 per cent in the green 

 cheese to 2.05 per cent in the fifth month, after which it gradually decreased to 

 1.75 per cent in the ninth month. The moisture decreased from 35.6 per cent 

 in the green cheese to 32.1 per cent at the end of the test. During the nine 

 months' curing there was a loss in weight of about 7 per cent. 



Paying for milk in cheese making, H. C. Troy (Hoard's Dairyman, 53 

 (lOlU), No. 15. pp. 6Jfl, 6//8).— The author gives data indicating that when the 

 increased energy value of cheeses made from milk of higher fat content is 

 taken into consideration, payment for milk on the fat percentage basis is 

 equitable. 



VETERINARY MEDICINE. 



Second biennial report of the Oregon State Live Stock Sanitary Board for 

 the year ended November 30, 1916, W. II. Lytle et al. {liicn. lipt. Orcg. 

 Live Slock Sanit. Bd., 2 {l'.H5-16), pp. 121, figs. ;S).— The three parts of thi.s 

 report deal, respectively, with finances and legislation, the occurrence of and 

 work with infectious diseases of live stock, etc.. particularly tuberculosis, 

 contagious abortion, and hog cholera, and a rejwirt of the Boanl of Sheep Com- 

 missioners, dealing especially with the occurrence of sheep diseases. 



Report of the parasitologist, J. W. Scott (\Vyoming Sta. Jipt. 1016. pp. 

 88-01). — In reporting upon the transmis.sion of swamp fever in horses, in con- 

 tinuation of work previously noted (E. S. R., 32, p. 754), it is stated that circum- 

 stantial evidence points very strongly to the stable fly as one of the agents 

 implic.ited in its transmission, and that transmission experiments with jnos- 

 quitois have given negative results. 



Feeding experiments with Ta-nin {}fonic:ia) vxpansa have faileil to produce 

 infestation in lambs. Further work with Thysattosoma artinioides has helped 

 to substantiate the conclusion that standing water, or at least a swampy area. 

 is a neces.sary condition for infestation. The work with Sarcocystis tcnclla 

 shows that lambs may become infested with this sarcocystid by eating grass and 

 certain kinds of insects. 



[Report of the] division of animal industry, V. A. Norgaaud {[Rien.] 

 Rpl. lid. Comrs. Ayr. ami Forestry Jlatcaii, 1015-16, pp. 119-165. p/.-«. 12).— 

 In the main part of this report the author and L. N. Ca.se report upon the occur- 

 rence of and work with diseases of live stock, particularly hog cholera and bovine 

 tuberculosis. The report of the live-stock inspector, .1. Richard (pp. 138-143), 

 and the reports of four deputy territorial veterinarians are ;ii)pended. 



Animal diseases in Russian Turkestan caused by endoglobular parasites. 

 W. L. Yakimoff et al. {Bui. Soc. Paih. Exot., 10 (1917), Xo. 4, pp. 302-311).— 

 This article deals with the piroplasmo.ses, theilerioses, nuttallioses, and anaplas- 

 moses. 



On the development of Ascaris lumbricoides and A. suilla in the rat and 

 mouse, F. H. Stkw.\kt (Pnra.^itoloyy. (1917). Xo. 2, pp. 213-227. pi. 1, fign. 

 9). — It has been found that when eggs of ,4. lumhricnidvs or A. suilla conl.iin- 

 ing mature embryos gain entrance to the alimentary canal of the sewer rat 

 (.!/(/.<} dcruDianiis) or the mouse (}f. mu-tculus) they hatch. A certain propor- 

 tion of the larva^ thus liberated escape in the feces where under suitable circum- 

 stances they live for at least three days, but probably ultimately succumb. The 

 majority of the larv.T gain entrance into the body of the host, some animals 

 showing signs of illness as .soon as the second day after infection. 



" Larvte are found in the lungs and liver of the host not later than four days 

 after infection and possibly as early as two days. . . . Larva; are not fouinl
