exportation of cattle. The commission recommends the following measures in con- 

 trolling foot-and-mouth disease: Prohibition of the importation of ruminants and 

 hogs, raw products of these animals, or other material which may serve to carry the 

 contagion from countries which are infected with the disease. At times when no 

 cases of the disease are known certain regulations are recommended as necessary to 

 he observed in order to prevent as far as possible all outbreaks of the diseases. These 

 measures include careful inspection of stock yards, slaughterhouses, stock trains, 

 steamboats, and stock markets. It also recommended that all stalls and yards which 

 are subject to infection from the disease should be regularly disinfected. In cases 

 of outl)reak of foot-and-mouth disease it is recommended that any delay or neglect 

 in notifying the authorities should be punished with heavy penalty, that strict quar- 

 antine conditions should be maintained, and that none of the animals in quarantine 

 or any of their products should be allowed to be moved from the place of quarantine 

 until the most thorough process of disinfection has been carried out. 



The intercantonal agreement concerning' the enforcement of simple regu- 

 lations for combating foot-and-mouth disease, J. Ehrhardt {Schweiz. Arch. 

 Tierh., 43 {1901), Nos. 3, pp. 11.5-123; 4, PP- ^^i?-i7-?).— Regulations for the control 

 of this disease have been formulated in 20 sections. The author gives a critical 

 explanation of the meaning and purpose of each of these sections. 



A new cure for foot-and-mouth disease, A. H. Dellschaft (Agr. flaz. {^Lon- 

 don], .54 ( 1901) , No. 1456, ]>. 3.51). — The author gives an account of the treatment for 

 this disease as recommended by Baccelli. The treatment consists in the intravenous 

 injection of corrosive sublimate. In calves, 2 to 4 cgm. are to be administered, accord- 

 ing to the severity of the attack; in adult cattle, from 4 to 8 cgm., according to size. 

 The solution of corrosive sublimate should contain 75 mg. of common salt for each 

 centigram of corrosive sublimate. 



On braxy, I). J. Hamilton {Trans. Highland and Agr. Soc. Scotland, 5. ncr., 14 

 [190,.'), pp. 314-347, figs. 3). — This disease is especially prevalent among sheep and 

 is identical with the disease known as bradsot in Teutonic countries. The author 

 gives a historical review of the literature on this disease and discusses the general 

 problems concerned with its diagnosis and nature. Braxy has a peculiar and limited 

 distribution. It appears to affect only European sheep and is most prevalent on the 

 West coast of Norway and of Scotland, and in Iceland. It is also prevalent on some 

 of the small islands north of Great Britain. The number of deaths among sheep in 

 certain seasons has l^een as great as 15 to 20 per cent. The symptoms are frequently 

 not observed, since braxy usually runs its course very quickly. The breathing 

 becomes somewhat labored and the temperature is elevated to from 105 to 108° F. It 

 is observed that the disease is most apt to attack young animals — laml)s after weaning 

 appear to lie most susceptible — while animals at 2 years of age are seldom attacked 

 and 3-year-old sheep are almost quite exempt. The greatest prevalence of the dis- 

 ease is observed during the late autumn and early winter months, although occa- 

 sional instances of braxy appear during the summer. Detailed descriptive notes are 

 given on the post-mortem findings in 6 cases of natural infection of braxy. The 

 pathological changes found in these cases agree closely with 3 other cases produced 

 by artificial infection. Braxy bacillus was readily found in all cases and is descril^ed 

 with reference to its various morphological and physiological characteristics. The 

 method of natural infection is not well understood, but it is believed that the bacil- 

 lus is inhaled in a dry condition. Work is being done at present for the purpose of 

 developing an effective preventive treatment for this disease. 



Acinous tumors of the g:all bladder in cattle, Zellhuber {Monatsh. PraJct. 

 Thier., 13 (1901), No. 2-3, pp. 97-120, pi. l,figs. .^).— The anatomical characteristics 

 of this disease are described in detail for 6 cases. The author concludes that the 

 mechanical friction of the tumorous swellings of the gall bladder prevents the dis- 

 appearance of the condition of inflammation and often renders this condition more
