This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1905 Excerpt: ...to be taken at 15.50; samples should be brought near to this. If at a few degrees above or below, it will suffice to make the determination at once and obtain the correct figure by reference to the annexed table. The specific gravity of normal milk varies between 1.028 and 1.035. Tnc ngure alone does not indicate the character of the sample, but taken in conjunction with the figure for fat or for total solids, it is of value as a check on the results furnished by other determinations. The simplest method of determining specific gravity is by the lactodensimeter, a delicate and accurately graduated hydrometer. The instrument must be immersed carefully so as not to wet the stem above the point at which it will rest. The instrument should be tested by immersion in distilled water at 15.50 and milks of known specific gravity. The indications furnished by the lactodensimeter are sufficiently accurate for most purposes, but its employment necessitates a considerable amount of the sample. More accurate determination can be made by the methods detailed in the introductory part (page 3), the most suitable being the Sprengel tube. According to Richmond, the pyknometer is less suitable for rigidly accurate work, on account of the tendency of the cream to separate before the mass has acquired the standard temperature. Total Solids.--This determination may often be made with sufficient accuracy for practical purposes by evaporating a measured volume (e. g., 3 or 5 c.c.) in a shallow nickel dish from 5 to 8 cm. in diameter. Nickel crucible-covers are suitable. The thin glass (Petri) dishes used for microbe culture are convenient. When greater accuracy is required, and especially when the ash is to be determined, platinum dishes must be used. Satisfactory results may be s...
