tent observers in the laboratory.Equal voluntes of Huid in test-tubes.Ten drops of acetic acid added to each test-tube.Each test-tube inverted slowly three times, so as to insure thorough, equal, and uniform mixing in all.Taking up this table a little more in detail, wo see that there was found to be no difference in the coagulation of raw, boiled, or steamed milk ; also that, practically the size of the curd depends on trie dilution of trie albuminoids, rather than on any especial property belonging to the substance with which the dilution is made.With lime water the result is the same as with water in equal amount, and barley water only shows a fractional difference from the results with plain witter.In these exper- iments also there was found to be ne» perceptible difference ¡is to the rapidity of trie coagulation of the different fluids, and that cow's milk taken directly from trie udder was found to coagulate in just as large curds as when twenty-four hours old.It might also be added that when a few drops of mer- curic nitrate solution was added to human milk, a decidedly larger curd was formed than when this reagent was added in the same way to cow's milk diluted one, part to five of water.In order to see if the statement so often made that atténuants act mechanically by getting, as it were, between the particles of the coagulum during coagulation, and thus preventing their running to- gether and forming a large compact mass, 1 have lately experimented as follows with various sub- stances :-In each of six test-tubes of equal caliber and con- taining 6 o.e. of hot water, 10 ce. of milk was placed.In test-tubes 2, 8, 4, 5, and 6 was added equal por- tions respectively of Mellin's Eood, Robinson's Barley, Imperial Granum, cracker crumbs, and bread crumbs.The albuminoids were coagulated ¡is before with acetic acid, and trie following results were obtained: Test-tube, I.
