If the ducts are injected before making a microscopicalpreparation, or treated with Golgis method, which stains theentire system of excretory channels a uniform black, the lumencan be followed into the alveoli, and is seen to end in terminaldiverticuli, which penetrate between the cells, and enter for ashort distance into the protoplasm (Fig. 20, A, B). Both the serous and the mucous salivary glands are suppliedby two kinds of nerves,
