Chemical and physical analysis of milk, condensed milk, and infants' milk-foods, with special regard to hygiene and sanitary milk inspection : a laboratory guide, developed from practical experience, intented for chemists, physicians, sanitarians, students, etc. Milk; Infants. 26 The apparatus constructed for this purpose by the author is ar- ranged as follows:. ^ is a flask of from 5 to 6 centimeters in width and 6 to 7 cen- timeters in height. On this stands the funnel B, the neck of the funnel being carefully adjusted into the neck of the flask by grinding. The funnel is from 6 to 8 centimeters wide and from 8 to 10 centimeters high. The upper edges, d d, of the funnel are bent outward to allow of an easy adjustment of the cork, and the lower aperture must remain of full width, and should not be narrowed down, as is often done.* The filter containing the precipitate is then loosely inserted into the funnel, which then is adjusted to the previously weighed flask. The filter is now washed with some absolute alcohol to remove the last traces of moisture from the precipitate. The beaker, which had been used for the coagulation, and which had been set aside, is now freed from fat by repeatedly washing it with small quantities of ether, which are poured upon the filter. This is continued until the flask is filled to about one-half with ether. The apparatus is then, by means of a good cork, free from pores,f connected with an inverted Liebig's cooler, and put upon a * An ordinary wide-necked flask, to which the funnel is attached by means of a good cork, may serve in the place of the complete apparatus, as described. f Corks may be prepared by covering the outer surface with silicate of .
