    most beautiful exlnbitions I ever witnessed), towards the neg. pole, or in the lines of current. All these experiments, together with 113 and 115, in which, apparently, thousands of ovoid corpuscles made their appearance, many of which were attracted in beautiful lines, and formed rods, and many of them can still be seen in the specimen, resulted in the formation of perfectly formed Fibrin, without scarcely a vestige of unchanged albumen being left. Dr Miller declares (page 808) that, when Fibrin is treated with acetic acid under the microscope, it is found to consist of two portions, one of which is granular and soluble in acetic acid, while the other is fibrinous and insoluble. This we found to be a graphic description of what took place with Fibrin ab albumen. EPITOME OF EXPERIMENTS. I.—Solution. Exp. 9 and 69.—Fibrin ab albumen dissolved in 3 min. in Liq. Potassse. Exp. 66.—Blood Fibrin was completely dissolved in twelve hours, whilst ov. albumen required more than tiventy-four hours to effect its solution without heat. Here this substance was much more dissimilar to albumen than even Blood Fibrin itself. Exp. 52.—In strong hydrochloric acid, Fibrin ab albumen and Blood Fibrin boBi dissolved in tiuenty-four hours, whilst ov. albumen was not completely dissolved in sixteen days. II.—Precipitated Solutions. In solution in acids precipitated by alkalies—and in alkalies precipitated by acids—this substance always manifested the same reactions as Blood Fibrin, and also equally differed from those of albumen. Exp. 57 to 63 and 68. In the Fibrinous solutions precipitated, lue had always Fibrinous rods and formations of Fibrin without the coayulum peculiar to albumen. In the solutions of albumen precipitated.
