,52)._Thr anatomical structure of the mammary gland of various domesticated ani- 

 mals is discussed andanaccounl is presented of the physiology of secretion. The 

 diseases to which the mammary gland is Bubjecl are discussed under the general 

 heads of injuries, acute mastitis, chronic mastitis, and malignant tumors. The 

 injuries studied by the author include contusions, wounds, abrasions, calculi, obstruc- 

 tion^ etc. The chronic forms of mastitis discussed by the author are those due to 

 Bfcreptococci, botryomycosis, actinomycosis, tuberculosis, etc. 



Milk fever and the new treatment of Schmidt and Evers, \'\a i;o\\y I Rt v. 

 y;t. \ Toulouse], SO I 1905), No. ?, pp. 81-88).— The author describes in considerable 

 detail 6 cases of milk fever which were treated by means of air. Asa rule, the air 

 teas pumped into the four quarters of the udder until this organ was in a tense con- 

 dition. The result in all cases was very satisfactory. The author believes thai the 

 rapid amelioration in these cases, after treatment with air an. 1 other successful meth- 

 ods, is not due entirely to the elimination or neutralization of the toxins which pre- 

 sumably cause the disease. 



East coast fever, Jabvis | Natal Agr. Jour, and Min. Rec, 8 I 1905 I, No. .\ pp. 188- 

 f4£)._In the author's opinion the only remedy which has given satisfactory results 

 in the control of African coasl fever is dipping in an arsenical solution. Instances 

 are cited where the ticks were nearly all destroyed as the result of dippingand with- 

 out excessive expense. On one farm the disease was apparently eradicated by thor- 

 ough dipping of all cattle. The arsenical solution did not appear to injure the cattle 

 seriously. 



Methods adopted in dealing with east coast fever, S.JB. Woollatt (Natal. 

 Agr. Jour, and Min. Eec, 8 {1905), No. 2, pp. 178-188).— The symptoms and patho- 

 logical anatomy of this disease are described in considerable detail, strict quaran- 

 tine measures have been adopted in controling the disease, and in some instances 

 cattle have been moved to high grazing ground for the purpose of getting them 

 beyond the reach of infection. This method is of doubtful value, however, since the 

 jfeease has been known to prevail in altitudes of 5,000 ft. 



Some points to be considered in connection with Rhodesian redwater, 

 S. Stockman {Jour. Compar. Path, and Tker., 18 {1905), No. l. pp. 6^72).— Immu- 

 nity toward this disease is not well understood. The contusion of opinion which 

 prevails regarding this matter may be partly due to the fact that the African coasl 

 fever has frequently been mistaken for ordinary Texas fever. 



It is not absolutely certain that cattle of a truly indigenous race are born immune. 

 It appears certain that the disease is spread by ticks which haw uA upon the viru- 

 lent hi I of affected animals. If such cattle pass alonga road it may readily become 



infected, and susceptible cattle must subsequently he kepi away from such roads until 

 the infection is destroyed. 



Tests of substances for tick destruction, ('. P. Lounsbur* [Agr. Jour. <'<i}>< 

 Good Hope, 26 I 1905 I, No. 3, pp. 387-895).— During the year L904 a number of expe- 

 riments were made in the continuation of an investigation of insecticides for ticks. 



In previous years arsenite of soda with or without the addition of soap was found 

 to he a cheap ami efficient remedy for the destruction of ticks. In subsequent tests 

 Stockholm tarwas added to arsenical dips, hut this increased the cost of the dip con- 

 siderably. Stockholm tar has the advantage of being a good dressing for wounds 

 and of itself is an insecticide of considerable value. The comparative test was made 

 between simple arsenic dips ami arsenical solutions containing tar. A tar-arsenic- 

 soap dip was also tested as a tick destroyer. 



The last-named dip proved no more efficient than simple solutions of arsenite of 

 soda, although the latter dip contained slightly less arsenic. Arsenical sprays were 

 found not to harm any of the cattle which were used in these tests. The frequent 

 dipping of sheep in arsenical preparations, however, causes considerable injury to 

 the sheep, and unless great care is exercised a heavy mortality.
