and Wohl (ibid., 1432) have shown that when nitrobenzene is reduced under certain conditions, /3-phenylhydroxylamine is formed.This compound is readily oxidised to nitrosobenzene, so that the latter, originally obtained as a green oil by Baeyer by the action of nitroagl bromide on mercury diphenyl (Bey., 1874, 7, 1638), can now be obtained in fairly large quantities. Bsteyer showed that, by the * Since sending in this paper, I have received a private communication from Professor Meldola in which he states that he has prepared metamidoazobenzene by the same method which I have employed. Professor Meldola has found that it is a coloured compound, and has the same properties as the substance described by me.I would also call attention to tlie paper by Meldola and Burls (Proc. Chem. Sop., 1893, 124, 126), which I liad overlooked, in which they intimate their intention t o study mettt-azo-compounds, and describe metaphenolazo-a-naphthylamine ; also to the paper by Meldola and Hanes (Proc. Chem. SOC., 1894, 140, 140), in which inetanitrobenzene-azo-a-naphthalene, metanitroamidoazobenzene and metuniti.oazobenzene are described.
One hundred and twelve Campylobacter strains comprising 15 species and subspecies were examined for their ability to hydrolyze indoxyl acetate. All strains of C. coli, C. cryaerophila, C. fennelliae, and C. jejuni hydrolyzed the compound, whereas three strains of C. cinaedi were negative and a fourth was weakly positive. Representatives of all other species were negative. Organisms that hydrolyzed indoxyl acetate did so regardless of the medium used.
solution the pain will be relieved without the use of an ano¬ dyne. He believes in the starvation, or rather the water treat¬ ment of infantile diarrhea; the use of the various diluted broths, such as barley water, amounts to little else. The water is improved, in his opinion, by aerating it.Dr. Rosa Enoelmann, Chicago, said that physicians who work in the dispensaries and slums see other insects, such as fleas, bedbugs and cockroaches, that are not above suspicion as disseminators of disease. A possible instance of this came under observation not long ago in Chicago. In a large apart¬ ment house containing about twenty families five cases of typhoid fever were reported. The first case developed on the lower floor, and the second case on the same floor, in the apart¬ ment on the opposite side. The two families on the floor above moved away, leaving that floor vacant. In the course of a month the third case developed on the third floor, and subse¬ quently two more cases developed on the fourth floor. The source of the infection could not be traced to the water sup¬ ply (artesian), to the milk nor to the ice. It was learned, however, that this apartment house was absolutely overrun with cockroaches, contaminating the food supply. In the apartment house opposite, where there were no cockroaches, with the same water supply, no cases of typhoid fever were re¬ ported. It was unfortunate that none of the cockroaches was caught and allowed to run over a culture medium, and thus proved to be the source of the infection; since they, of all in¬ sects, are water inhabitants and consequently probable disease carriers. Investigation should be done along these lines, as has been done with fleas and bedbugs in respect to plague.Dr. Wm. T. Watson, Baltimore, said that the mothers in his practice are, most of them, very busy women, who can not afford to employ nurses. He likes to make things as easy for them as possible. He thinks that Dr. Kilmer's advice to boil nursing bottles for an hour is carrying precaution to an un¬ necessary extreme. Surgeons do not boil their instruments for an hour. According to Rotch, all bacteria are killed at a temperature of 154 F., and Abbott says that all pathogenic bacteria and their spores are killed by five minutes' boiling. Boiling for five minutes ought to be enough for the disinfec¬ tion of bottles, which is merely surface disinfection. During the past few years Dr. Watson has been feeding an increasing number of babies on raw milk. The milk comes from the Walker-Gordon farm and is modified at home. Where the mothers are intelligent he finds no trouble to arise from feed¬ ing this milk raw. He asked Dr. Southworth if he considers this a rash practice.Dr. William L. Stowell, New York City, said that raw milk for infant feeding has been used at the Children's Hos¬ pital a portion of the time for the past six years. At present they are vising the gravity cream from their own dairy. The milk was given raw, except in extremely hot weather, and he was surprised to see how weak children thrived on i...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
