readers to the experimental researches of M. Bernard respecting the glycogenic function of the liver, which formed the first volume of his " Lectures on Experimental Physiology." We propose now to notice a more recent production of this distinguished physiologist, which consists of his summer course of lectures, delivered in 1855. The chief points discussed and illustrated by experiments on living animals in this second volume, have reference to the character and functions of the salivary glands and the pancreas in the digestive process. While this latter organ is made the leading object, and the importance of its functions is somewhat highly coloured, the foreground is filled in, not without considerable elaboration, with a description of the different salivary glands and their secretions. In the background the liver, the bile, and the gastric secretions are worked in with some effect. Briinner's glands obtain a passing notice, from their proximity to the leading organ. All these organs and secretions are but secondary effects, introduced into the picture for the purpose of enhancing the grandeur and importance of the principal object. The salivary secretions, the gastric juice, and the bile, have, it is admitted, comparatively useful purposes to serve in the animal economy ; but they are not for one moment to be confounded or compared with the " universal solvent," the grand agent of chylification?the pancreatic juice. While we admire the skill and indomitable energy with which M. Bernard "pushes" the claims of any organ or secretion which he has once taken under his
