Tristeza, J. Ligxieres (yin?i. Inst. Pasteur, 15 {1901), No. 2, pp. 121-128, pi. 1). — 

 Tristeza is the name for a cattle disease in Argentina, which is identical with 

 Texas fever. The author quotes the results of investigations upon this disease, 

 during which the results already oljtained by American students are largely con- 

 firmed. It is stated also that the examination of blood, although the most important 

 element of diagnosis ante-mortem, is not an infallible test. An atyj^ical form of the 

 disease is occasionally observed, in which the destruction of red blood corpuscles is 

 not very pronounced, or takes place slowly, and in which the corjiuscles in general 

 circulation are not attacked by the blood parasite until shortly before death. It is 

 maintained that this form of the disease does not correspond to the benign form 

 already described by the American writers. The author succeeded in making cul- 

 tures of Pyrosoma bigemmum in a round form, and showed bj' experiment that the 

 administration of quinin and arsenical compounds has no effect in i->reventing or 

 curing the disease. 



Tristeza or Texas fever in the Arg-entine Republic, J. LicixiERES {La "tris- 

 teza^' ou malaria bovine dans la Republique Argentine. Buenos Ai/res: Jacobo Peuser, 

 1900, pjp. 172, pis. 16). — A i:)reliminary accomit of work on this subject has already 

 been noted (E. S. R., 12, p. 885). The present volume contains a detailed account 

 of the author's observations and experiments on this disease. 



Parturient paralysis and the Scliniidt treatment, J. J. Repp {lovxt Sta. Bui. 

 58, pp. 17-30) . — A general account is given of the history, distribution, cause, i^atho- 

 logical anatomy, symptoms, diagnosis, course, and treatment of parturient paralysis. 

 The author considers this name preferable to either parturient paresis or milk fever. 



In order to determine the effectiveness of the Schmidt treatment, as applied by 

 the practicing veterinarians of Iowa, a circular letter was sent to 150 veterinarians 

 requesting a report on the number of cases treated and the history of those cases. 

 In all, 166 cases were reported to the author by 33 veterinarians, of which 119 cases 

 were reported as successful, while 47 were fatal. The majority of the affected cows 

 were between the ages of 6 and 9 years, and at the birth of the third to the sixth 

 calf. Most of the cows were reported as being fat and at pasture, not receiving any 

 other food. As a rule, the affected animals Avere heavy milkers. The disease 

 developed usually within 24 hours after parturition. The infusion of potassium iodid 

 was repeated in from 8 to 12 hours in 22 cases, and in 2 cases was repeated twice. 

 In 6 cases the disease was complicated with pneumonia and resulted fatally in each 

 case. The author believes that pneumonia may be the result of attempting to give 

 medicines by way of the mouth when the animal is vniable to swallow. The mate- 

 rial might under such circumstances be carried into the lungs and produce an infec- 

 tion of these organs. In 7 of the cases which were treated a more or less serious 

 affection of the udder was produced, probably from the use of instruments which 

 were not properly sterilized. Allowing for cases which were complicated with 

 pneumonia and other trouble, the author considers that 76.5 per cent of cures is to 

 be placed to the credit of the Schmidt treatment. This treatment is recommended 

 as being the most effective one which has yet been devised. 



Parturient paresis, S. S. Buckley {Man/land Sta. Bid. 76, pp. 199-201). — The 

 author jiresents a brief account of the Schmidt treatment for milk fever, together 

 with formulpe for solutions to be used and directions for applying the treatment. 

 The usual symptoms of milk fever are mentioned, and statistics are given on the 

 percentage of cures effected by the Schmidt method. Of 7 cases treated by the author, 

 6 recovered. In 2 cases which recovered severe attacks of mastitis subsequently 

 developed. 



Milkfever, E. W. Koare {Veterinarin, 74,{1901), Xo.879,pp. 138-140).— The author 

 had good success in the treatment of milk fever by administering chloral hydrate in 

 doses of 1 oz. and treacle in doses of 1 lb., followed by ammonium carlionate. In 

 one case the cow received in all 7 oz. of ammonium carbonate and 9 I'os. of treacle.
