The mixing process is carried on in the following manner: the ordinary soap of commerce is sliced up, and with it is mixed the above material or materials in the proportions above described, the whole is then put into a suitable vessel to be melted, water being added to aid the operation.* When the ingredients are properly mixed, the contents of the vessel is allowed to cool, and then is to be cut out into bars, as is usual in such

cases.

The Patentee states, that he finds the proportion of about one half of the siliceous materials to one half by weight of the saponaceous materials to be the best proportion for common soaps, and that the ingredients must not be mixed in any other proportions than those above mentioned, viz. from one eighth to three fourths, as the desired effect will not be obtained if the ingredients are mixed in any proportions either more or less than these.

For making fancy or toilet soaps, the Patentee uses curd, instead of yellow soap, and he lessens the proportion of the siliceous ingredients.

In conclusion, the Patentee states, that he does not mean or intend to claim as his invention the application of any siliceous material to the manufacture of soap, as he is aware that such materials have been applied to cleansing before; but he claims as his invention the ap plication of the above-named materials in the before

*The Patentee here states, that the siliceous ingredients may be added before the soap is allowed to cool, when it is manufactured; and it must be evident that this is the most economical way for the manufacturer.

mentioned proportions: viz. from one eighth to three fourths by weight of the siliceous ingredients, to from seven eighths to one fourth of the saponaceous materials in the manner above described.-[Inrolled in the Inrolment Office, October, 1834.]
