The muscle-substanceis never directly continuous with adjacent tissues, but is alwaysenclosed within the sac of the sarcolemma; the union between thefibres and other structures is effected by the blending of the endo-mysium of the muscle-fibres with the connective tissue of the attach-ments, whether these be tendon, periosteum, perichondrium, orsubcutaneous tissue; the sarcolemma closely invests the sarcouscontents, being simply received into the connective tissue withoutbecoming directly continuous. CARDIAC MUSCLE. The muscular tissue of the heart, as well as of the cardiac ends ofthe large veins, forms an intermediate group of contractile tissue,standing in its development betwe
