milk show a clieinically toxic effect which persis^ts for only ;i short time. Ap- 

 parently the effect is exerci.setl upon the vasomotor nerve center and produces an 

 irritation and paralysis of these structures. According to these experiment'^, 

 milk fever could be considered as due to an abnorm:il increase in the quantity 

 of these injurious substances in milk. 



The treatment of milk fever, S. R. Ferwerda {TijdscJn: ]'ce(trtKCiiijh-.. 3Jf 

 {11)01), yo. 7, pp. -i-}-J--J-'/i5). — Brief notes are presented on the results obtained 

 in the treatment of 1(50 cases of milk fever by means. of air pumped into the 

 udder. In nearly all of these cases marked improvement was observed within 

 n few hours and only 1.3 per cent of the cows died. 



The treatment of infectious vaginitis, .J. Vlaskamp {Tijdschr. Vecartseiiijlc, 

 3.'f {11)01), ^o. 7, PI). JfSD-JiJi'i). — The symptoms of infectious vaginitis are briefly 

 described aud notes are given on the occurrence and spread of the disease. The 

 author obtained best results in treating the disease from the use of an ointment 

 containing pyoctanin. In these experiments ichthyol was not used, but it is 

 believed that tkis might also l)e of some lienetit. 



Different species of trypanosoniata observed in bo vines in India, A. Lin- 

 card {.Jour. Trap. Tci. iici.. 2 {1901), 'So. l,.pp. Ji-50, pis. 3). — A long series of 

 observations has been made on trypanosoniata as found in various bovines in 

 India of the hill and plains types. The species of trypauosomes thus far 

 observed include T. evansi, T. himalayanum, T. uiuktemii, and T. bidicinu in 

 hill cattle, the last-named species being also found in plains cattle. 



The methods of reproduction and other jioints in the biology of the obser^ed 

 trypauosomes are discussed in detail, and a table is given showing the average 

 measurements of diftVrent species. 



Observations on some •worms found in the aortas of buffaloes and bullocks, 

 (J. L. Tuck {-Jour. Trop. Vet. Sci., 2 {1907), Ao. i, pp. 69-100). — Two sjiecies 

 of parasitic worms belonging to the family Filariida^ were foiuid, one in the 

 aortic walls of the buffalo and one in domestic cattle. A large percentage of 

 buffalo and cattle was found to be infested with these worms. Each small tumor 

 in the aortic or arterial wall contained a single parasite. 



A detailed description is given of the anatomical features of the aorta and 

 of the minute characters of the parasitic worms. The anatomical features of 

 these parasites are shown by way of comparison in t.ibular form. 



Nodules containing larval nematode worms in the intestinal submucosa 

 of a bullock, J. B. Cleland {Jour. Trop. Vet. ScL, 2 {1901), Xo. 1, pp. 61, 68).— 

 In the course of meat inspection a number of small nodules were found in the 

 subnmcosa of the small intestine of a beef animal. The nodules were readily 

 movable and appeared to be in close relation Avith the blood vessel in every case. 

 Each nodule contained 1 or 2 nematode worms which have thus far not been 

 identified. 



Trichinosis: A danger in the use ^f raw pork for food, B. H. Ransom {U. 8. 

 Dcpt. Agr., Bur. Auiiii. Indus. Circ. 108, pp. 6, figs. ■'>). — The trichina is described 

 in its 3 stages and notes are given on the symptoms of trichinosis in man. its 

 treatment, and the frequency of the occurrence of the disease in man aud hogs. 



In preventing this disease in man, attention is again called to the fact that 

 no further precaution is necessary than the thorough cooking or preparation of 

 pork before it is eaten. The trichina^ are killed with certainty either by thorough 

 cooking or curing. 



The etiology of hog cholera, Schreiber {Berlin. Ticrtirztl. Wchnschr., 1901, 

 So. 18. pp. 299-0111). — The author has succeeded in producing both the chronic 

 and acute forms of hog cholera by experimental inoculation with pure cultuies 

 of Bacillus suipestifcr. Success was also had in producing an active imuiunity
