characteristic, which is an accepted dogma. The following experiment 

 refers to the mode of resolution. 



March 24th, 1861. On examining the web of a frog which had 

 heen inflamed with tincture of iodine the day previously, I watched 

 a vessel in which the homogeneous stasis existed, and observed the 

 stasis to resolve in a peculiar manner. A normal current, such as is 

 usually seen in capillaries, was circulating in the direction from A to 

 B (fig. 1,) and impinging 

 on the contents of the ob- 

 structed vessel C. Thestag- 

 nation in the vessel C ap- 

 peared to thaw as it were. 

 The corpuscles were not 

 pushed onwards in the 

 mass, but seemed to take 

 on the appearance of the 

 impinging current, and the parts so reduced from the homogeneous 

 to the heterogeneous condition did not appear to contain any great 

 excess of corpuscles. This action soon extended through the whole 

 length of the vessel, and immediately this was consummated a perfect 

 current set in as in fig. 2. At the extreme edge of another division 

 of this web I noticed two stagnated loops as in fig. 3. The circula-

tion around them was in full activity. These I watched for more 

 than an hour, and observed them to become gradually much lighter 

 in colour, passing from a deep red to a pale orange. The point of 

 junction C retained its depth of tint much the longest. All this time 

 the contents of the vessels maintained perfectly their homogeneous 

 character. At length all at once the outlines of the corpuscles be- 

 came visible as in fig. 4, and the circulation was re-established. In 

 this case, as in the previous one, there was no pushing on before of a 

 plug of adherent corpuscles, but a gradual permeation of the liquor
