Outside of this cellularlayer, the poison duct is made up principally of white fibrous tissue, with a smallproportion of very fine fibres of yellow elastic tissue. The walls of the duct areprovided throughout with an abundant supply of bloodvessels. Just above the line of the lip, and consequently at the base and outer side ofthe maxillary bone, the duct, in turning to descend this bone, becomes abruptlylarger, for a distance of a line, o
