In treating of the Dr. Buchanan, Dr. Turner (Portsmouth), Dr. Parsons theories of causation, he stated that those usually accepted- (Goole), Inspector-General Lawson, Dr. C. J. Hare, Dr. viz., artificial feeding, impure water, and maternal neglect- Thorne Thorne, Mr. Netten Radcliffe, and the President, took part. were not supported by the statistics of Oldham, Halifax, and other large towns, where the mortality from this disease was small, and where these conditions were certainly not wanting.. In towns engaged in similar branches of industry and employing the same proportion of female operatives, the death-rates from this disease were subject to very considerable variations.

(THE TROMMER EXTRACT OF MALT COMPANY, FREMONT, OHIO.) We find that this extract converts starch into glucose and dextrine rapidly and in large quantity. In flavour it is excellent, and we have therefore no hesitation in praising it highly. Malt extract seems to be steadily increasing in favour for diseases involving impaired nutrition; but its preparation requires great care, as it is easy, in making it, to destroy its activity as a starch-converter, and so render it nearly useless. The malt extract is supplied in various forms-for example, the simple, for nutrient purposes, with cod-liver oil (which it disguises pleasantly), with the hypophosphites, and with iron.

The annual deathas it affected both adults and infants during the summer months, owed its origin in the great majority of instances to rate in the twenty towns, which in the four previous weeks the introduction of these living organisms into the system had declined from 323 to 27’1 per 1000, was last week by means of air or food, and that the disease depended upon equal to 28’1.
