Complete section of mesenteric nerves 



Exudation of watery fluid. Loop half full of fluid, and 

 containing some loose mucous flocculi. 



Loop distended with grey watery fluid containing gela- 

 tinous flocculi. Surface of mucous membrane soft, 

 thickened and covered with a gelatinous layer of 

 material similar to the flocculi. Fluid strongly alka- 

 line ; smell mawkish and choleraic ; contained about 

 ^th of albumen. Flocculi composed of exudation 

 cells. Gelatinous layer on mucous membrane com- 

 posed of similar cells in a mucoid basis. 



p]xudation of fluid ; reddish ; sp. gr. 1,009 ; alkaline ; 

 containing albumen. 



Loop distended with fluid ; pinkish grey ; strongly 

 alkaline ; odour choleraic ; sp. gr. 1,006. Surface of 

 mucous membrane soft, thickened and covered with 

 a loose yellowish layer of exudation cells. 



Mucous membrane soft, moist and thickened, but no 

 exudation. The ligatured loop was situated ip the 

 jejunum. 



Loop fully distended with fluid ; reddish ; sp. gr. 1,005 ; 

 alkaline ; containing a few flocculi. 



Loop fully distended with fluid. 



Loop contained an abundance of fluid. It was situated 

 in the jejunum. 



No fluid in the loop. 



Fluid exudation. 



No special exudation in the centre loop. 



Loop full of brownish gelatinous exudation containing 

 numerous large bioplasts. 



Abundant exudation of fluid. 



Loop almost empty. 



Loop fully distended with fluid ; straw coloured ; alka- 

 line ; sp. gr. ] ,008. 



Loop fully distended with fluid ; alkaline ; containing 

 an abundance of granular exudation cells. 



Loop distended with fluid, swarming with bacteria and 

 vibriones. Post-mortem some hours after death. 



Loop distended with fluid. Mucous membrane thick- 

 ened and moist. 



Loop fully distended with fluid, watery, almost colour- 

 less ; sp. gr. 1,005 ; reaction alkaline. A few project- 

 ing flocculi containing exudation cells on the surface 

 of the mucous membrane. 



No special exudation in the ligatured loop. 



It will be seen that a copious secretion of fluid was the almost invariable result 

 of section of the nerves, entirely independent of detachment of the epithelial cover- 

 ing of the mucous membrane, but sometimes associated with the occurrence of an 

 exudation of bioplasts upon its surface ; and that the secretion occurred as well in 

 cases in which the division of the nerves was complete as when it was only partial. 

 These results are similar to those obtained by us in the greater number of the experi- 

 ments of this nature which we referred to on a former occasion, and are quite in 

 accordance with those obtained originally by Moreau. Moreau's experiments have
