94 EXPERIMENT STATION RECORD. 



station is described and also a number of experiments. Of 1,176 hogs 

 treated for cliolera C59 were saved, or 56 per cent. The conclusion is 

 drawn from the experiments that serum injected alone has only a limi- 

 ted power of immunity. Good results were obtained at the experiment 

 station farm by injecting about 10 cc. of antitoxic serum to 1 cc. of viru- 

 lent hog cholera culture, according to the weight of the animal. 



On the immunity of the Gallinaceae to human tuberculosis, Lannelonguk 

 and Archaro (Compt. Rend., 124 (1897), No. 17, pp. SS3-8S5). — The author's observa- 

 tions partly confirm the general belief that gallinaceous birds are immune to human 

 tuberculosis. He states that the bacilli inoculated into a fowl remain alive there 

 and retain their virulence for a considerable time, sometimes several months, but 

 their virulent period does not differ from that of bacilli that have not touched 

 a fowl's body. To prove this last assertion he introduced bacilli sealed in a glass 

 tube uuderthe skin of towls and of pigeons. Open tabes were also employed. The 

 results were all the same. In conclusion the author says that the immunity seems 

 to be due to loss of generative powers by the bacilli. The immunity, however, is 

 only partial. 



Tuberculosis in Maryland (Nat. Stockman and Farmer, 21 (1897), No. 7, p. S.) — 

 It is stated that tin- state "sanitary live stock board has reports showing that 10,000 

 head of cattle have been examined in the State and that 1± per cent were found 

 infected. 



On the actinomycosic form of the bacillus of tuberculosis, V. Barks and C. 

 Levaditi (Compt. Bend., 124 (1897), No. 14, pp. 791-793).— To the published state- 

 ments of themselves and others the authors add that actinomycosis often recalls. 

 especially in man. certain forms of abcesses or of osseous tuberculous lesions, and 

 that actinomycosis reacts to tuberculin. The authors recall the various forms pre- 

 sented by actinomycosis and the bacilli of tuberculosis, and conclude that the latter 

 must be placed in the same group as the former.

 Inter nat. Jour. Micros, and Nat. Sci., 3. ser., } 1891 . No. 34, jn>. 149, 150). — Note is 

 made of the use of hydrochlorate of anilin and alcohol for decolorizing sections 

 stained with carbolized fuchsin.

 Cattell (Internat. Med. Mag., 1S96, Dee., pp. ; abs. in Internal. Jour. Micros- 



and Nat. Sci., 3. ser., . Vo. 34, pp. 1ST, 188). — In tins method tissues to Lie sec. 



tioned are prepared as in the method advised by < >rth in a mixture of Miiller's fluid 

 (1 part) and formol | 10 parts , after which I hey are washed and dehydrated in alco- 

 hol. This is then removed or not used and the tissues frozen in formol and gum 

 arabic by spraying with a mixture of methyl chlorid from above.

 Sci., 3. ser., 1 (1897), No. 34. pp. 115, 116). — Tissues are frozen and sectioned on an 

 ether spray microtome. The sections are removed to a I per cent formalin solution, 

 thence to a 4 per cent alum-carmine solution for :'» to 5 minutes. The sections 

 are then rinsed in water and dehydrated by leaving for 15 seconds in 80 per < ent 

 alcohol and for the same length of tune m absolute alcohol, after which they are 

 placed in xylol-carbol and finally in Canada balsam.
