the tissue of the liiii^s. In advanced cases tbe nodules become densely clustered 

 tosether. 



The symptoms and post-mortem lesions are carefully outlined for the purpose; 

 of assisting in a differential diagnosis between the disease and white scour, 

 pleuro-pneumouia, and other diseases with similar symptoms. The disease in 

 question appears to be able to remain in a latent condition in the animals and 

 breaks out in acute form when, for any reason, the resisting power of the ani- 

 mal is lowered. Treatment of the disease is for the most part without avail. 



Scab: Its' nature, cause, symptoms, arid treatment, D. Hutcheon (Agr. 

 Jour. Cape Good Hope, 32 (1908), No. 4, pp. 433~-'f4S, figs. 11).— The symptoms 

 of scab in various animals are outlined and notes are given on the different 

 species of mites which cause scabies of different sorts, together with a brief 

 discussion of the complaints which have been raised by wool dealers as to the 

 injury caused to wool by the use of certain dips. "Wool dealers are by no 

 means of the same opinion on this point. 



The author considers that in the treatment of scab no other remedy can 

 compete with a mixture containing sulphur, and recommends a lime-sulphur 

 dip containing 25 lbs. of sulphur and 18 lbs. of lime in 100 gal. of water. A 

 formula is also given for the preparation of a sulphur and caustic soda dip 

 for sheep and goats. 



Anemia and pasteurelloses, J. Lignieres (BuI. 8oc. Cent. M6cl. Y6t., 85 

 (1908), No. 8, pp. 187-190). — Since evidence has been furnished that hog 

 cholera may be produced by a lilterable virus independently of the so-called hog 

 cholera bacillus it has been suggested that perhaps other bacteria which have 

 been referred to the pasteurella group may be of secondary pathogenic im- 

 portance. The author combats this theory and argues that the hog-cholera 

 bacillus differs in many respects from the other members of the pasteurella 

 group. 



Swine erysipelas, H. Holth (NorsJc Vet. Tidsskr., 20 (1908), No. 5, pp. 

 113-126). — The present status of swine erysipelas in various European countries 

 is outlined and statistical data are given regarding the prevalence of the dis- 

 ease and the percentage of mortality. In localities where preventive vaccina- 

 tion has been thoroughly applied the prevalence of swine erysipelas has been 

 greatly reduced. 



The occurrence of the bacilli of swine erysipelas in the gall bladder of 

 hogs which have recovered from the disease, W. Pitt (Centbl. Bakt. [etc.], 

 1. AM., Orig., J/G (1908), No. 5, pp. JfOO-JfOo). — From the observations and 

 experiments thus far made it appears that the bacilli of swine erysipelas per- 

 sist longest in the gall bladder of recovered animals and may be found in that 

 organ after they have disappeared from all other parts of the body. The 

 bacilli may be found in recovered hogs after attacks from mild or acute cases of 

 the disease. Tlie bacilli found in the gall bladder are viable and virulent. 



A germ-free extract for the prevention of swine plague, Pfeil (Berlin. 

 Tierarzil, Wehnsehr., 1908, No. 11, pp. 301, 302).— On an estate badly infected 

 witli swine plague the author inoculated 45 hogs with a mixture of polyvalent 

 swine-plague serum and a germ-free extract of the bacillus of swine plague. 

 All of these animals were immunized by this treatment and remained healthy, 

 while check animals living under the same conditions became infected in a 

 large percentage of cases. 



The poisoning of hogs by kitchen swill, H. Fresenius (Atti 6. Cong, In- 

 ternaz. Chim. Appl., Jt (1906), pp. 457-461). — ^An account is given of an out- 

 break of poisoning among a herd of hogs fed on the swill from the kitchen. 



Chemical examination of the stomach contents in one case indicated the pres- 

 ence of traces of mercury, copper, and lead. Attention is called to the fact that
