Mr., GuWiver's Contributions to the 



false membrane, (Gerber's Anat., fig. 272), and the parallel 

 arrangement of the fibrils with the same appearance in fibrine 

 obtained from blood out of the body (I. c. fig. 246). 



Case 3. — A child 18 days old died of inflammation of the 

 peritoneum, on the surface of which was some friable coagu- 

 lated lymph.

Fig. 5. The exudation just mentioned. There are some 

 corpuscles, and an abundance of minute molecules. One of 

 the corpuscles appears to be made up of objects like the pri- 

 mitive discs of Dr. Barry. Compare this friable exudation 

 with that, fig. 2, in which the molecules were absent. 



Structure of Fibrinous Exudations in Birds. 



It would be interesting to examine the organic germs in 

 the fibrine of animals with blood-discs differing widely from 

 those of man ; and, as remarked by Dr. Carpenter in his 

 valuable work on Human Physiology, p. 471, observations of 

 this kind should be multiplied, in order to test the accuracy 

 of Dr. Barry's views respecting the origin of the tissues and 

 of pus-globules from the blood-discs. 



The fibrine obtained by washing from the blood of birds 

 contains a multitude of particles, which are figured in the 

 Philosophical Magazine for August 1842, like the nuclei of 

 the blood- discs. I had recently an opportunity of examining 

 some large amber-coloured and nearly transparent clots of 

 fibrine from the peritoneum of a silver pheasant. 



Fig. 6. A, corpuscles in the exudation from the bird just 

 mentioned. The connecting fibrine is very minutely granu- 

 lated, and the granules are so arranged in some parts as to 

 present a very faint appearance of fibrils; but some of these 

 seemed to be quite smooth, and they are somewhat too di- 

 stinctly represented in the engraving. B, filaments about
