Experiments have also shown that a dog with as much as 69 

 per cent, of hemoglobin tied up with carbon mon-oxide which 

 corresponds to the end of the second stage, can be resuscitated if 

 proper treatment be instituted promptly.

Intestinal excretion during diarrhea. 



By GEORGE B. WALLACE and HUGO SALOMON. 



\_Froin the Laboratory of the Von Noorden Clinic, Vienna^ 

 Analyses were made of the faeces of a number of patients with 

 diarrheas of different origin. During one period of observation 

 the patients were on the Schmidt-Strassburger diet, during a sec- 

 ond period the diet consisted of 250 grm. sugar daily. In those 

 cases where there was present an ulcerative process in the intes- 

 tine — tuberculosis, carcinoma — the amount of nitrogen in the 

 faeces was markedly increased — being from 1.7 to 4. grm. daily 

 on the sugar diet. In cases of severe catarrhal inflammation it 

 was not over 1.5 grm.; in light catarrh it was within normal lim- 

 its. The fat and carbohydrate elimination showed no such strik- 

 ing differences although it was highest where an ulcerative condi- 

 tion was present. Of the inorganic constituents the alkali excre- 

 tion was fairly parallel to that of nitrogen. The other inorganic 

 constituents were increased by the ulcerative processes but in 

 some instances were increased equally where ulcerations were 

 absent. 



The most striking result of the analyses is the high nitrogen 

 excretion which occurs in ulcerative processes in the intestine.

 Quantitative determinations of the blood-flow through the left 

 kidney were made with the aid of the stromuhr of Burton-Opitz. 

 On stimulation of the central end of the sciatic nerve, a slight de-
