84 EXPERIMENT STATION RECORD. 



hand on the dial face. A spring on the back of the dial keeps a steady tension at the 

 ends of the "brass arms, enal)ling them when inserted in and drawn up the sides of 

 the glass bottle neck to adjust themselves instantly to any variations that may occur 

 and to manifest the same by a jnovement of the pointer." Bottles showing decided 

 irregularities are further tested by tilling to the zero mark with mercury and adding 

 0.5 cc. ijortions from a specially devised burette. 



VETERINARY SCIENCE AND PRACTICE. 



Therapeutic observations {Ztsdir. ]'e(erindrk., l.J {1901), Xo. 5, j>p. 213-234)- — 

 Experiments were tried with injections of carbolized water in the treatment of teta- 

 nus. Of 8 cases treated in this manner, 4 recovered and the other 4 died. Carbo- 

 lizeil water in a 2 to 3 per cent solution was injected subcutaneously, twice per hour, 

 in doses of 5 to 10 gm. In the treatment of tetanus with antitoxin, 9 out of 15 horses 

 which received the antitoxin died, while 6 recovered. In some cases another form 

 of treatment was adopted during which, in addition to the antitoxin, a serum was 

 injected which had been obtained from a horse previously infected with tetanus. 

 According to experiments of Kammerhof the administration of antitoxin in some 

 cases brings about a rapidly fatal course of the disease. 



Several experiments are reported in the treatment of parturient paresis with iodid 

 of potash. Unfavorable results were obtained in only 3 cases. The remedy was 

 applied in the way of infusions into the udder. 



The same substance was also tested in the treatment of metritis, with i-esults which 

 left it doubtful whether recovery was entirely due to the administration of iodid of 

 potash. 



Experiments were tried with creolin in the treatment of anthrax in cattle. Creo- 

 lin was given by way of the mouth and also in clysters in water. The treatment 

 gave good results. 



Detailed notes are given on the results obtained by a number of army veterinarians 

 with colloidal silver in the treatment of morbus maculosus in horses, catarrhal 

 fever in cattle, septic processes, phlegmonous infection, and in the treatment of 

 wounds. 



Therapeutic observations iZtschr. Veteriiidrk., 13 {1901), Xu. (!, pp. 272-291). — 

 Reports are made on experiments with two silver preparations — citrate of silver, also 

 known as itrol, and silver lactate, known in trade as actol. These antiseptic sub- 

 stances in experiments thus far made have proved to be as effective as the colloidal 

 silver preparation of Crede. Notes are also given on a large number of antiseptic 

 preparations which have been used in the treatment of wounds and septic processes. 



The culture of anaerobic bacteria, H. Hammerl {Centbl. Bali. u. Par., 1. Abt., 

 30 {1901), No. 17, i^p. 658-664). — The chief difhculty experienced in the culture of 

 anaerobic l)acteria is the production of strictly anaerobic conditions. Nearly all 

 of the various devices which have been employed in such experiments have been 

 defective to the extent that during some part of the experiment oxygen was allowed 

 to enter into the atmosphere surrounding the bacteria, or into the nutrient medium. 

 In order to prevent the access of oxygen the author reconunends that an anunonium 

 suljihid meduuu be placed in a glass vessel and that the neck of the vessel be closed 

 with a loose sterilized plug of cotton from which ail fat has been removed. The 

 lower half of the cotton plug should be saturated with solution of pyrogallic acid. 

 The upper portion of the plug should be protected with a rubber cork. Care must 

 be exercised that the pyrogallol should not come in contact with the nutrient 

 medium, and the cotton must be absolutely free from fat. 



The dissemination of infectious diseases by insects, C. F. Dawson (Ainer. 

 Vd. Her., j,5 {1901), Xo. 4, pp- 2fiH-272}. — A brief review of the literature on tliis 

 subject. Among the insects which are mentioned as possible carriers of disease are 

 bedbugs, house flies, tsetse flies, mosquitoes, and cattle ticks.
