Conclusions available from these data and from observation are as follows:
a. The constants and fatty acid composition of Sample A correspond to those
obtainable from a stock consisting chiefly of tallow (probably mutton
tallow) with a possible small percentage of cocoanut oil,
The constants and fatty acid composition of Sample B could possibly be
satisfied by a grease in which there was a higher ratio of stearic to
palmitic acid than is ordinarily found in greases available for soap
manufacture in the U,S,A,.
The high glycerine and free fat content of Sample A indicate that it was not
a boiled soap. and that it was made from poorly split stock,
The free fat content ofSasp3e B indicates that it was not a boiled soap,
It is estimated that neither sample was a milled soap,
Both soaps contained a yellowish brown dye which became bright red in acid
solution,
The higher glycerine content of Sample A gave it a sami.-translucent
appearances
ho Sample A was scented with a civet type perfume, while Sample B contained
a perfume similar to that used for Ivory soap in the U.
