Perfect Soap. Accordinp; to Mignot, a perfoct soap is One in which the fatty matters and the alkaline have been so thoroughly combined as to leave no excess of either component - a desiderátum which is very seldom reached, as the soap is either too alkaline, in which oase it parches and dries up the skin, or it is too fat, and thus makes the skin greasy, go that the dust readily adhereg to it. The farmer inconvenience is the more serious of the two, as it very soon leaves its impress upon the skin. For this reason soapmakers nre in the habit of employing an exces of fat. notwithstanding tho inconTenience mentioned. Mignot now inforrus us that lilicia introduced into soap, in the form of infusorial earth, will tend to neutralize an excess of tho alkaline elomontg of the eoap, as it is soluble both in soda tnd in potash, nnd it will at the same tima take up she surplus of fatty matter by absorbing it, and combining with it to a certain extent. Infusorial eprth, aa ia -wfll known, oecm-s iñ different parts of the world in great quaiitity, and immense deposita are known in vaiious portions of the United States, especilly in Idaho, Nevada, and California.
