In some parts of the body a kind of intercellular substance is formed, which differs in many respects from the foregoing. It is highly elastic, does not give gelatine on boiling, and is not affected by weak acids or alkalies. In bulk it has a pale yellow color, and is spoken of as yellow elastic tissue. It is sometimes found alone, forming an elastic band or ligament, but more commonly mingled with fibrillar tissue to form the connecting medium which lies under the skin and between the various other textures.
