The author made a detailed .study of alterations in the structure of 

 the red blood corpuscles during the various stages of the disease. 

 Notes are also given on the diminution of the number of red corpuscles. 



The whole subject of the development of J^i/roxoiiKi Ithjiiainum is 

 I'eviewed in detail by the author. It is stated that all pyriform hema- 

 tozoa assume a round form at one stage, and that this is a natural and 

 not merely an accidental form in the (Unelopment of the parasite. 

 The round form was found in the organism in c.)nsideral>le abundance, 

 especially when the disease began to decline. In no case did the round 

 form become metamorphosed directly into a pyriform hematozoon. 



The author succeeded in following the development of the l)lood 

 parasite of Texas fever in artiiicial cultures, and in connection with 

 the known fact of the existence of ))oth a mild and an acute form of 

 the disease, raises the question as to whether these two forms of the 

 disease may be due to two forms of the blood parasite. 



Parturient apoplexy under Schmidt's treatment, J. H. Tennext 

 {Jour. Conq>. Jfd. hikI Yrf. Arrh.^ )>! {1!)U0). Xn. J, j^P- 286-292).— 

 The author applied Schmidt's treatment in the following manner: A 

 quart of boiling water was poured into a clean vessel and when cooled- 

 to a temperature of 100^ F., 1 dram of formalin and 1^ drams of 

 potassium iodid were added and the whole was gently shaken. The 

 cows which were to be treated were thoroughly milked and the udder 

 and teats were washed with antiseptic solutions. Eight ounces of the 

 solution of formalin and potassium iodid in water were injected into 

 each quarter of the udder through the milk ducts of the teat. Treat- 

 ment which accompanied the use of Schmidt's treatment consisted in 

 the removal of feces from the rectum and the use of a catheter incases 

 where urine was retained over 12 hours. No medicines were given hy 

 the mouth unless the patient was able to stand. Detailed notes are 

 given on the history and treatment of 15 cases of parturient apoplexy, 

 of which 13 recovered and the author ])elieves the other '2 cows would 

 have recovered but for the intei'ference of the owners. Some of the 

 worst cases mad(? the most speedy recovery. Considera]:)le difficult}' 

 was experienced in keeping up the heart's action, but this was success-

A preliminary report upon forage poisoning in horses (so-called 

 cerebro-spinal meningitis), L. Pearson {Jour. (Jomp. Med. and Yet. 

 Arch.. 21 {lOUO). A'o. 11. pp. 601^-657).— T\iQ author investigated an 

 outbreak of disease among T horses of which 5 died. The symptoms 

 were those of i)aralysis. which atfected the throat first and gradually 

 extended to other parts of the body. Two of the 7 liorses which were 

 removed from the l)arn ultimately recovered. A silo had been opened 

 about a week before the first cases Avere noticed. :uid as the silage was
