Nevertheless, we havethis great vessel springing out of this last network; andsince this can effect no action in the peptic glands—being atthe free end of the tubes—it must have reference to otherimportant functions, either absorption, or else to pour out gasin the intestine ; most probably both are included. It will thusbe seen from the arrangements that obtain in the parts, thatrapid absorption is made inevitable from the very nature ofthings, dialyzable with nou-dialyzable substances, otherwiseinexplicable; notably, the rapid absorption of alcohol,which should never enter the circulation at all, never-theless is rapidly absorbed ;* since the high pressure, which.
