VETERINARY SCIENCE AND PRACTICE. 1021 



author it has been extensiveh' tried in different countries and some of the results of 

 practical experience are brought together in the present article. The author has 

 experimented with pumps for introducing air into the udder in connection with his 

 original treatment. In 140 cases the average length of time between the beginning 

 of treatment and recovery was 65 hours. It is lielieved that tiie use of air hastens 

 recovery in almost all cases. An elaborate discussion is given on the subject of the 

 etiology of this disease. Potassium iodid is known to possess a pronounced antitoxic 

 action and the author believes that the effect of this treatment must be largely due 

 to local action of the chemical in the udder. 



On the treatment of parturient paresis, J. .Schmidt {Maanedsskr. Dryhvger, 

 14 {1902), No. 5, pp. 19J-J12). — The author gives a resume of the literature relating 

 to the treatment of this disease by means of potassic iodid. Notes are also given on 

 the injection of various other substances into the udder, such as warm water, iodin- 

 potassic-iodid, sodium iodid, potassium bromid, etc. It is believed that the most 

 important moditication of the potassic iodid treatment which has thus far been pro- 

 posed is the use of sterilized air. This may be pumped into the udder alone or in 

 combination with and following the potassic-iodid treatment. The chief advantage 

 of the air treatment is that cows recover the normal flow of milk in a comparatively 

 short time. — f. w. woi.i.. 



Treatment of parturient paresis by iodid of potash., Nevekmanx (i>V;'^/H. 

 Thierdrztl. Wchnschr. , 1902, Xo. 27, pp. 402, 403) .—The Schmidt treatment for this dis- 

 ease h^s given satisfactory results as a rule but the effectiveness of the treatment has 

 been attributed to various factors. It has recently been found that the treatment is 

 i;endered more rapidly effective by forcing considerable quantities of pure air into 

 the udder in connection with the infusion of iodid of jiotash. Theauthor recommends 

 the introduction of air into the udder after tlie infusion in cases of parturient paresis. 

 A new treatment of parturient paresis, E. Thierry [Jour. Agrkole [P<in!<\, 

 14 {190S), No. 154, pp- 9-13). — Notes are given on the good results recently obtained 

 from the use of filtered air in connection with potassium iodid as a treatment for 

 parturient paresis. It is believed that this disease will in most cases yield to treat- 

 ment more rapidly when filtered air is used in addition to potassium iodid. 



Parturient paresis before parturition and the theory and treatment of 

 this disease by means of filtered air, A. Teetz {Berlin. Tliieriirztl. Wch)isdir., 1902, 

 Nu. o2, pj). 474-476).— The autlKir describes a number of cases of this disease which 

 occurred before parturition. Some of the cases were observed before the placenta 

 was loosened, and some of them exhibited an intermittent course. The author 

 believes that j^arturient paresis is due to excessive anemia of the brain, and that this 

 condition is explained by the unusual flow of blood from other parts of the body to 

 the udder at the beginning of the period of lactation. It is suggested that the intro- 

 duction of air and the infusion of iodid of potash into the udder might have the 

 effect of forcing out some of the blood from this organ, and thus relieving the cerebral 

 anemia to a certain extent. 



Subacute parturient paresis and its treatment with air, A. Teetz {Berlhi. 

 Thierarztl. Wchnschr., 1902, No. 43, pp. G44, 643).— The techni(iue of introducing air 

 into the udder is briefly described. In one case of parturient paresis air was pumped 

 into all 4 teats of a cow affected with this disease. Considerable improvement in the 

 condition of the animal was noted within 1 of an hour, and within r> hours she was 

 able to get up. A rapid recovery followed this treatment. 



Simple treatment of parturient paresis, Evers (Rt^/u. Tliicrarzil. Wclinscltr., 

 1902, No. 32, p. 473, fig. i).— The author describes an apparatus devised for intro- 

 ducing pure air into the udder of cows affected with parturient paresis. The appa- 

 ratus consists of a rubber bulb, a metallic cylinder in which cotton batting may be 

 introduced for filtering impurities out of the air, and a suital)le smooth needle con- 

 nected with rubber fulling.
