    . \A It E 8 E A R CUES COMPARATIVE STRUCTURE OF THE LIVER. BY JOSEPH LE1DY, M.l>. WITH TIIKKK PLATKS. [Extracted from tlie American Journal of the Medical Sciences for January, 1848.] The following observations* on the comparative structure of the liver were made solely for my own satisfaction, but I have been induced to make them public from the impression that some of tin- facts presented may be new, or that, at least, the anatomy of the liver being presented in B somewhat new aspect, may be better understood than by former methods of description. It will be remarked that as respects the anatomy of the liver of verte- brated animals, the facts observed by me corroborate the very carefully made researches and accurate descriptions of the anatomy of the human liver by Mr. Kieruan. (Philosophical Transactions, London, 1833.) The constant presence of the liver throughout the whole of the vertebrate series of animal life and the higher orders of the invertebrate series, is sufficient proof of the importance of the organ, in connection with the digestive apparatus. It is an extensive secreting surface collected into a small bulk, and in the vertebrata it is arranged in such a complex manner, that before the researches of Mr. Kieman, anatomists entirely failed in obtaining any satisfactory knowledge relative to us arrangement. Before entering upon the details of the anatomy of the liver, it may be well to examine in a verv general manner the nature of secretion and the or„ns which possess ibis function. It is rather difficult to give a good general definition of the term secretion, for there are many organic pro- . ru, baervattOM were made With an excellent microscope manufactured by Oberboeuser, o!
