The ceruminous glands of the ear resemble the sebaceous glands. SECTION III. MUSCLES. Muscles are formed of that substance usually called flesh, which has a peculiar contractile power, producing motion ; they consist, independently of the cellular tissue, vessels, and nerves, which enter into their formation, of a special tissue, resembling the middle coat of the arteries. Every muscle is composed of a number of bundles of fibres, each of which consists of filaments ; each fila- ment is divisible into fasciculi, and each fasciculus consists of a num- ber of primitive particles or sarcous elements^ held together by a tough, delicate, and elastic membrane called sarcolemma. The fibres of the voluntary muscl(^, as well as the fibres of the heart and some.
