PART I.] Injections of Organic Solutions, not Choleraic, into Veins. 107 



get rid of any large particles which might have been floating in the mixture), were 

 injected into the left femoral vein of a dog, into whose right femoral vein some putrefy- 

 ing blood had been injected three days previously without any very marked result, 

 although he was evidently far from well (^ide, Exp. LlII). 



The dog quickly recovered from the effects of the chloroform, took to his food 

 readily, and by the third day was so far improved as to have managed to make 

 his escape. 



Experiment XLIV. — Half an ounce of perfectly fresh sanguineous peritonitic 

 fluid was injected into the right femoral vein of a large healthy pariah dog which 

 had been previously placed under chloroform. The fluid had been obtained from the 

 peritoneum of a dog in whom peritonitis had been produced by the introduction 

 of a solution of normal evacuation into the abdominal cavity {vide Exp. LXXIV). 



The animal continued somewhat dull and sluggish throughout the day : the 

 following day it was more lively, but a large inflamed swelling had appeared around 

 the seat of the incision. On the fourth day it was very much improved, and seemed 

 to have nearly recovered. On the fifth day it was again put under chloroform, which 

 was pushed until respiration ceased. A post-mortem examination was immediately 

 made, but not the slightest sign of peritonitis nor of embolism could be traced, the 

 only lesion observed being the inflammatory condition of the wound in the thigh. 

 The bladder was full of urine, and the mucous membrane of the intestines perfectly 

 healthy. 



(6) — The organic solution injected being one day old. 



Experiment XLV. — A healthy young puppy was put under chloroform at 8 a.m., 

 and three drachms of a fluid composed of mixture of water, and healthy foecal 

 matter which had been prepared twenty-four hours previously, were injected into the 

 right femoral vein. The dog recovered perfectly from the effects of the anaesthetic, 

 but died at 11 a.m. of the same day, three hours after the operation, having passed 

 several mucous stools in the interval, although the first stool passed after the 

 operation presented no such appearance. 



A post-mortem examination was made at 4 p.m. of the same day, and we found 

 that the peritoneal cavity contained reddish serous fluid. The peritoneum was not 

 injected, and there were no signs of inflammation of the membrane. The stomach was 

 empty, containing also about an ounce of glairy fluid, its mucous coat healthy. The 

 duodenum was deeply congested and contained thick yellowish mucus. 



The congested surface, when wiped, resembled the hairs of a hair pencil when 

 flattened out. In the jejunum the fluid was more watery and closely resembled 

 that found in the intestines in cholera cases. In the lower part of the ileum there 

 was less congestion of the mucous membrane, the contents here were foecal and
