It was less solid, less resistent, and of less specific gravity, so that, despite its bulk, Magendie supposed its actual mass to be less considerable than that of a similar bulk of normal fibrin. He terms it, iherefoTvpseudojibrm. Examined by M. Fremy, the chemist, it was found to liquefy or melt when exposed to a temperature of 60 Cent. (140 Fahr.) in a sand bath, while true fibrin does not dissolve by heat, but dries and becomes brittle. Such pseudo-Jibrin, it is scarcely necessary to remark, could be no fit substitute for true fibrin in the process of nutrition, if this be, as there is so much reason to believe, a nutrient substance; and if the pseudo-Jibrin so rapidly imparted to the liquor sanguinis in defibrinated animals, be regarded as an imperfectly elaborated blood-fibrin, hurried into its place when the normal fibrin had been artificially withdrawn, under the operation (in the abnormal circumstances deranged or modified) of that law which presides so remarkably over the proportional composition of the blood--preserving its constituents in a definite relation to one another in health, and striving to restore them to that relation when it has been accidentally disturbed--we have a suificient explanation of the rapid emaciation which occurred in the defibrinated animals; for not only had the normal nutriment of the tissues been lessened by the defibrination, but that which had been hastily furnished to supply its place was defective and incompetent.
