Corpuscles are seen scattered throughout the mass, and some detached ones, d, are represented below. Their of a perfect tube, invests every elementary fibre, average diameter is one-thousandth of an English inch. adheres to its surface, and isolates it from sur- rounding parts. It is universally present in vo- luntary muscles, and may be demonstrated in a variety of ways. When the fibres have been im- mersed in alcohol, which causes them to shrink, it is often seen wrinkled on their surface; or when they are cracked or broken across, it fre- quently remains entire and connects the severed fragments (fig. 294). This method of showing Fig. 294.

When thus forced out it usually collects between the fibre and its sheath, raising the lattefin the form of bullae (figs. 301 and 302, and Art. MUSCULAR MOTION). The progress of this in- teresting phenomenon evinces the adhesion that exists between the fibre and its sheath. The bullae immediately subside, by the transudation of their fluid, when the part is placed in thick syrup. I once met with a singular demonstration of the existence and properties of the sar- colemma, in finding it filled with nu- merous trichina (fig. 296), which had taken the place of the contractile ma- terial, the sheath preserving all its cha- held to eth
