Commentaries on the surgery of the war in Portugal, Spain, France, and the Netherlands, from the battle of Roliça, in 1808, to that of Waterloo, in 1815; with additions relating to those in the Crimea in 1854-55, showing the improvements made during and since that period in the great art and science of surgery on all the subjects to which they relate. Revised to October, 1855. to Miilder—although it is doubtedby Liebig—is a complex substance, consisting of severalheterogeneous organic compounds united into one whole,easily acted upon by strong reagents. If a protein compound be brought into contact with analkali, ammonia is immediately disengaged, and the alkalinesolution can hardly be made weak enough to prevent thedisengagement of ammonia. If either fibrin or coagulatedalbumen be dissolved in a weak potash ley, ammonia isalways perceptible. Protein, therefore, is always in a stateof decomposition, as serum is alkaline. In diagram No. 3, fig. 3, the organic or involuntarymuscular fibers of the intestine are shown, consisting of moreor less flattened bands, the fibers of which are soft, andmarked with minute granules, sometimes exhibiting traces ofnuclei. These purely muscular fibers are most abundantnext to the inner coat of the artery, and diminish in numberas they approach the outer layer, their place being occupied STRUCTURE OF ARTERIES. 181 No. No. 4. by firmer and more elastic fibers of a yellow color, seen col-lectively in tlie circular diagram, as line 4, and separately indiagram 3, fig. 4, and in diagram 4. The iyivoluntarymuscular fibers of anartery do not alwaysform a continuouslayer ; they are oftensmaller than thosefound in the intes-tines, bladder, anduterus, and occur asfusiform cells, de-tached from eachother, and having alarge, club-shapednucleus, as shown atfig. 6 in diagram 3. The voluntarymuscular fibers differfrom the involun-tary, in having cylin-drical fibers of muchlarger size, with trans-verse and longitudinal
