inoculation. Immunization b_v means of bile is a method ^Yhicll in 

 general is too uncertain in its results to be recommended. 



Results of recent investigations on foot-and-mouth disease 

 and their practical application, C Ebertz {Arch. ]V!ss. a. l*r(i]d. 

 Thierh., '26 {1900), No. 2-3, pp. 155-20 }^).—T\iQ author presents an 

 elaborate critical review of the literature of this subject. A com- 

 mission which was appointed for investigating vaccination methods 

 against this disease did not carefully determine the virulence of the 

 l3'mph which was used for this purpose, its value, nor the varying 

 susceptibility of the animals which were to be inoculated. 



The author considers in a critical manner the results obtained from 

 the application of Lofler's seraphthin method and Hecker's inocula- 

 tion experiments against foot-and-mouth disease. The author believes 

 that the reports which have hitherto been made on the A^alue of 

 various methods in controlling this disease are to some extent vitiated 

 by the failure to make allowance for the large number of exceed- 

 ingly mild cases which are nearl}- always to be observed in extensive 

 outbreaks of the disease. The author states that numerous experi- 

 ments carried out under government control according to Hecker's 

 inoculation method show that in its present form it is not adapted to 

 the production of such results as have been claimed for it. 



Sheep scab, A. W. Bitting {Indiana Sta. Bui. 80, p>p. 63-76, 

 fcjH. 8). — The author gives a general account of the nature of this 

 disease and a description of the parasitic mite which causes the dis- 

 ease. Brief notes are presented on the dips to be used for the 

 destruction of the scab mite and on the methods of applying such 

 dips, together with a description of dipping tanks. The State statisti- 

 cian secured reports from sheep owners which indicate that sheep 

 scab existed in 320 localities in the State and that 9,338 sheep w^ere 

 affected. Further inquirj- developed the fact that some other condi- 

 tions which caused roughness in the fleece had been mistaken for seal). 



The bulletin contains a copy of the live-stock law of Indiana afl'ecting 

 the spread of sheep scab and the regulations of this Department con- 

 cerning the dipping of sheep which are afi'ected with scab. 



Scab in sheep — suggestions for its eradication, AVallace {Trans. 

 HigJiland and Agr. Sac. Scotland, 5. ser., 12 {1900), pj). 117-137). — 

 The author gives statistics compiled from circulars of inquirj^ which 

 show that the most serious outbreaks of sheep scab occur during the 

 winter months. A brief outline of the life history of the scab mite is 

 presented. On the subject of dipping, the author gives a general dis- 

 cussion of the peculiar local conditions which must be considered in 

 this operation throughout Scotland and Wales. In the mountainous 

 regions of Wales about 45,000 sheep belonging to 300 ownei>s are 

 grazed. These sheep are in herds of from 5 or 6 up to 2,000. These
