On the other hand, it is possible that pancreatic digestion may be indirectly influenced through an action of the absorbed alcohol upon the secretion of pancreatic juice and, indeed, upon the secretion of bile. This point, however, we have not attempted to determine, since there was little promise of results of any value for the present inquiry. For various reasons, however, it has seemed desirable to ascertain what effect alcoholic beverages might have, if present, upon the proteolytic action of the pancreatic juice, since this is one of the chief functions of the secretion. As to the influence of alcoholic fluids upon the amylolytic action of pancreatic juice there is no cause for special inquiry, since, as is well known, the amylolytic enzyme of the pancreas is essentially the same as the enzyme of saliva, hence what has been found true of the latter fluid will doubtless apply likewise to the amylolytic action of the pancreatic juice. Influence of alcohol and alcoholic beverages on the digestion of proteid foods by pancreatic juice. The conclusions to be drawn from our experiments under this head may be briefly summarized as follows: Pancreatic juice in its proteolytic action is more sensitive to pure alcohol than gastric juice. Retardation of digestive action is more pronounced even with small amounts of alcohol, the presence of even two to three per cent. of absolute alcohol being sufficient to produce a distinct retardation of proteolysis. Still, as in the case of gastric digestion, the exact amount of retardation is greatly dependent upon the digestive power or concentration of the pancreatic fluid. When the amount of absolute alcohol present in the digestive mixture is less than one per cent. , the inhibition of proteolytic action. . .

The digested food is taken up by little hair-like projections on the inner coat of the intestines, called villi. These villi are full of little tubes--the lacteals--which carry the milkylooking food through a number of glands, and then unite to form one common duct, which passes upwards through the chest and opens into a vein in the neck. The liver, a large Fig. 118. --Diagram of the Circulation. The internal organs of all vertebrate animals are constructed pretty much on the same plan as in man, and they serve similar purposes. As might be expected, however, from his superior intelligence, the brain of man is much larger in proportion to his size than that of any other animal. Fig. 119. --Thorax and Abdomen laid open. The most remarkable variation in birds lies in the organ of respiration. In mammals the respiration is confined to the lungs; birds breathe not only through their lungs, but the air penetrates to every part of the interior of their bodies, even into the cavities of the bones. The lungs are fixed to the back of the thorax, and are comparatively small; their smaller size, however, is more than compensated for by the air-sacs which occupy the greater part of the cavity of the chest. The brains of reptiles are much smaller in comparison with their size than those of mammals and birds, and the surface in all is quite smooth. The spinal cord and the nerve cords, on the other hand, are more fully developed. The lungs also are much less efficient organs for aerating the blood than in the preceding classes; the respiration is consequently less active. . .
