    THE MYXOMATA. The myxomata are tumours consisting of mucous tissue. Mucous tissue is a translucent aud succulent connective tissue, the intercellular substance of which yields mucin. Physiologically, this tissue is met with in two forms, and in two situations :—one—in the vitreous body of the eye, in which the cells are roundish and isolated; the other— in the umbilical cord, in which the cells are fusiform or stellate, and give off fine prolongations which anastomose with one another. In both, the intercellular substance is homogeneous and yields mucin. The connective tissues in their embryonic condition, as already stated when describing mucoid degeneration, possess an inter- cellular substance containing large quantities of mucin. This is especially the case with the tissue which subse- quently becomes adipose. New formations may undergo a mucoid change, and thus closely resemble in their phy- sical and chemical characters the myxomata. A myxoma, however, is a growth which consists of mucous tissue. The myxomata are thus very closely allied to the sarco- mata, and by many are included in the same class of new formations. Structuke.—The cells present the two varieties met with in the physiological tissues. The majority arc angular and stellate, with long anastomosing prolonga- tions. (Mg. 35.) Others are isolated, and fusiform, oval, or spherical in shape. They usually possess one, in some cases two distinct nuclei. Their contour is very
