Thusconvoluted and packed up,secreting organ may be pro-cured to any amount thatmay be required, withoutthe inconvenience of bulkand weight. It is manifest, that the sim-plest form of the secretoryapparatus consists of simplecapillary vessel, and animalmembrane; and that thefollicles and glands arestructures of a more com-plex organization, but stillessentially identical; — allperhaps—as will be seenpresently—executing theirfunctions by means of cellagency. Or, to use theviews and lansjuagje of theday, every secreting organpossesses, as essential partsof its structure
