This is "whipped" or defibrinated blood, which has lost the power of coagulating spontaneously.

Place on a glass slide a thin layer of defibrinated blood; try to read printed matter through it.

Place in each of three test tubes two or three teaspoonfuls of defibrinated blood, obtained from Experiment 89, labeled A, B, and C. A is for comparison.

To fifteen or twenty drops of defibrinated blood in a test tube (labeled D) add five volumes of a 10-per-cent solution of common salt.

"If it was really blood at all, I should say that it was either defibrinated bloodthat is, blood from which the fibrin has been extracted by whippingor that it had been treated with an alkaline salt.

"You say that the blood found in the safe was defibrinated or artificially treated.

" "What is your explanation of the presence of defibrinated blood in the safe?"

"In the second place, that print was evidently made with the aid of certain appliances and materials, and one of those materials, namely defibrinated blood, was found in the safe.
