The evidence of such adulteration is most signally shown in the following proof, which is by one of the most eminent food analysts of Great Britain, viz.:
“I recently purchased, on the same day and in the same neighborhood, a series of eight samples of starch, paying for them three different prices. On subjecting them to analysis, I found the whole of them to be adulterated with 20, 30, and even nearly 40 per cent. of earthy or mineral matter. This I found to consist of mineral white, terra alba, or sulphate of lime.”—Letter in the London Times, October 5th, 1878.

Only a careful chemical analysis will show the pure article from the adulterated.
KINGSFORD’S OSWEGO STARCH
has been thus analyzed and proved to be perfectly pure and free from any foreign substance, as is proved by the following report:
THE ANALYTICAL SANITARY INSTITUTION.
London, January 1, 1879.
We have obtained in different parts of the metropolis samples of both the qualities of Starch manufactured by Messrs. T. Kingsford & Son.
We have examined them carefully, both with the microscope and by chemical analysis, and found the samples without exception to be of good color, of excellent quality, perfectly genuine, and of great strength.
