method of investigation consisted in the intnxhiction of aseptic foreign bodies into the 

 subcutaneous connective tissue. The liistological processes wliich are observed in tlie 

 formation of the new connective tissue are described in great detail. The elements 

 which are most important in the formation of these new tissue are the polymorphous 

 leucocytes, fibro1)lasts, and polyblasts. The fibroblasts are the ordinary connective 

 tissue cells which existed before the inflammation set in. They Ijegin to proliferate 

 at a very early stage of the intlammatifjn. The polyblasts are said to play an exceed- 

 ingly imj)ortant role in the formation of the new connective tissue. They are to be 

 characterized as am(i'l)oid wandering cells with a single nucleus. 



General histological technique -with special reference to the possibility of 

 a morphological demonstration of cellular narcosis, H. Za.N(;(;kk [\'rlljvrlir. 

 Naturf. Gesell. Zurich, 47 {190£), No. 1-2, pp. ^^-7^).— Detailed notes are given on the 

 technique of staining animal cells by various methods with special reference to 

 methods intended to demonstrate the presence of narcosis in various animal tissues. 



"Vasog-en preparations in veterinary practice, A. Homer [Dent. Tierarztl. 

 Wi-lmsclir., 10 [UK)/), Xnx. 47, pp. 449-4-'>.^; 48, pp. 4.5.5-457). — The vasogen prepara- 

 tions which have already been placed on the market by a firm in Hamburg number 

 20 or more. The author made experiments with a number of these preparations, 

 especially in the treatment of suppurative wounds. Iodoform, iodin, pyoctanin, 

 creolin, camphor, chloroform, creosote, and ichthyol vasogen were used, as well as 

 mercuric vasogen salve and vasogenum purum siiissum. In the author's experiments 

 with these materials it was found that a rapid penetration and absorption took place, 

 and the effectiveness of the preparations in inducing the process of healing was very 

 striking. No irritation appeared to be produced by these substances upon the skin 

 and no toxic effect was observed, whether used internally or externally. 



Silver therapy, Dorx {Berlin. TInerarztl. Wehiwhr., 1903, No. 27 , pp. 403-40.5) .— 

 Notes are given on the use of colloidal silver in the treatment of puerperal septicemia, 

 contagious coryza, and morbus maculosns, together with a l)rief account of the nature 

 and therapeutic use of protargol and itnjl. 



The present status of photo-therapy and its application in veterinary 

 practice, I. I. Neim.\x\n {Arch. Yd. Nauk, St. Petersburg, .H2 [190.J), Nu. Li, pp. 1017- 

 1029). — A critical review of the literature of this subject is presented in connection 

 with a bibliography. The author believes that light may be used under various 

 comlitions in the treament of animal diseases, and suggests apparatus and arrange- 

 ment of the same for convenient use in military veterinary hospitals and similar 

 institutions. 



Treatment of malignant edema with carbolic acid, with remarks upon 

 "leeches," or bursattee, C. F. Dawsox {.Tour. Gnnp. Med. and Vet. Arch.., 23 

 {1902), pp. 301,302). — In an operation wound made for the purpose of removing 

 a "leech " tumor, malignant edema developed. In treating the tumor for malignant 

 edema, injections of strong carbolic acid were used, 1 dm. being injected daily for 3 

 days. The formation of gas within the tumor was checked and extensive suppura- 

 tion occurred for some time, with recovery of the animal after 1 month. 



Accidents following upon preventive inoculation and bacterial associa- 

 tions, V. Galtiek (.Jour. Mid. Vet. rt Zootech.. .5. .^er., G {1902), Dec, pp. 097-703).— 

 I U-ief notes are given on accidental infections which maybe ])rought about during 

 the performance of preventive inoculation. It is believed that the association of 

 different bacteria may aggravate the effects of vaccination made with a benign virus 

 so that more or less serious results may attend what would otherwise liave been a 

 harmless operation. 



On the relationship of human tuberculosis to that of bovines, i). J. Hamil- 

 ton ( Tram. Highland and Agr. Soc. Scotland, 5. ser., 15 {1903), pp. ^32-278, figs. 3).— 

 The author discusses the difficulties of determining the possibility of transmitting 

 bovine tuberculosis to man, and also gives brief notes on the transmission of human
