The author prefers bacteria killed by heat to bacterial extracts, as the former 

 yield a more active and lasting immunity. 



Vaccines (Hochst's vaccine, Gans and Schreiber extracts, and porcin), are 

 suspensions of swine plague bacteria. In all probability these organisms are 

 killed according to Wright's directions for preparing vaccines by heating them 

 to about 60° C. With some of the lymphs, however, the bacteria, in addi- 

 tion to being treated in this manner, are disintegrated by special methods, while 

 others have an addition of swine plague serum, which is added for the purpose 

 of aiding in the solution of the organism after injection into the animal and 

 for the purpose of preventing a negative phase. The Euman lymph also has 

 an addition of swine plague bacilli. 



Mammary botryomycosis in the mare, W. Plotner (Monatsh. Prakt. Tier- 

 heilk., 23 {1912), No. 6-7, pp. 279-804, pi. 1, figs. 2; abs. in Vet. Rec, 26 {1914), 

 No. 1338, p. 559). — "Early extirpation of the mammary gland is the best treat- 

 ment for botryomycosis of the udder. lodids are not advisable as agents for 

 curative treatment, as the tumor, which is fibrous and not well supplied with 

 blood vessels, is but little influenced by their internal administration. lodid 

 of potassium, however, may be used in small and recent bbtryomycotic tumors, 

 and is also serviceable before and after the operation of extirpating the mam- 

 mary gland. Before the operation it disperses the phlegmonous swelling sur- 

 rounding the botryomycotic tumor, and thus facilitates surgical interference. 

 Afterwards it encourages the absorption of postoperative edemas and swellings."

In regard to protectively vaccinating against the pectoral form of equine 

 influenza (Brustseuche), D. Konew {Berlin. Tierdrztl. Wchnschr., 29 {1918), 

 No. 33, pp. 589-591). — In order to determine the immunizing properties of blood 

 containing the specific micro-organism isolated by the author, tests were made 

 with 80 sound horses present in a stable in which there were horses affected 

 with equine influenza. The injection was given subcutaneously in the side of 

 the neck in amounts ranging from 1 to 2 cc, the dose given being gauged accord- 

 ing to the size and age of the animals. Following the injection the animals 

 were not worked for 3 days and only one-third of the time for the next 4 days. 



None of the horses vaccinated became sick. On the other hand, the disease 

 occurred continually in other horses which were apparently sound at the time 

 the group was vaccinated. 



Following the above experiments vaccinations were made in the field and in 

 regions where outbreaks occurred, and to date about 667 animals have been 

 successfully treated. 



About protective and curative vaccination for the pectoral form of equine 

 influenza, Brombergee {Be7-Un. Tierdrztl. Wchnschr., 29 {1913), No. 33, p. 

 591). — A description of cases of the disease treated with Pfeiler's vaccine and 

 serum, serum alone, or with Bengen's Ozonal. The results obtained were 

 satisfactory. 



Nematodes of the genus Acuaria Brems. (Dispharagus Duj.) parasitic in 

 domestic fowls, A. Henry and P. Sizov {Arch. Vet. Nauk [St. Petersb.], 43 

 {1913), No. 7, pp. 609-637, pis. 9; abs. in Rev. Gen. MM. V6l., 23 {1914), No. 270, 

 pp. 303-306).— A report of systematic and biological studies." A bibliography of 

 58 titles is appended. 



Parasitism in relation to birds, H. V. Jones {Zoologist, 4- ser., 18 {1914), 

 No. 206, pp. 41-53, pi. 1). — This paper deals chiefly with the Cestoda, Acantho- 

 cephala, and Nematoda found in the alimentary canal of some of the common 

 birds. A table is given which shows the month, locality, food of bird, and posi- 

 tion of the parasite when found. A list is also given of 24 species of birds ex-
