Similarly, the determination of the amount of fibrin in the blood is a matter that must be left to proficient chemists. The French have taught that the quantity of fibrin may be determined by a study of the reticulum formed under a coverglass. This teaching is certainly very far from accurate. Even if the method were reliable, the quantity of fibrin in the blood is of little practical importance.
