tural granulated structure of the internal membrane is in- 
creased in size by the effects of inflammation. Besides 
which, there are small globular exudations of coagulable 
lymph, like studs, on different parts of the surface. 
Plate XXIII. 
This Plate contains four figures, representing the internal 
membrane, and the muscular structure surrounding it, at 
the strictured part. The three first figures are magnified 
twenty-five diameters, the fourth fifty. 
Fig. 1. Shows the exudations of coagulable lymph in 
masses of different forms and sizes, and the enlarged glands, 
nearly uniform in their shape, and of a smaller form. 
Fig. 2. Shows the longitudinal muscular fibres, and the 
masses of coagulable lymph deposited between the fasciculi, 
increasing the volume so much, as to produce the narrow 
aperture or stricture. 
Fig. 3. The same muscular fibres, having the fasciculi 
more separated from one another. 
Fig. 4. The same fasciculi separated still more, and nearly 
into their ultimate fibres.
