392 THE EXCRETIONS: 



acid, and acetate of lead. The precipitate thrown down by 

 alcohol was soluble in an excess of water, which was rendered 

 turbid by the addition of acetic acid, and yielded a copious 

 precipitate on the subsequent addition of ferrocyanide of potas- 

 sium. 



As the ash, after incineration, consisted of carbonate of soda, 

 I regarded the substance insoluble in alcohol as an albuminate 

 of soda. 



The quantitative analysis of this " vomitus a3ruginosus seu 

 herbaceus" yielded the following proportions in 1000 parts : 



Analysis 154. 



Water ..... 971-0 



Solid residue ..... 29-0 



Fat 4-3 



Bilifellinic acid, alcohol-extract, and bile-pigment 

 Spirit-extract with a little bilifellinic acid . 

 Albuminate of soda

[Heller 1 analysed a brilliant green fluid vomited by a young 

 woman aged 20 years, suffering from peritonitis. 



In quantity it amounted to about three ounces; it was 

 slightly turbid, and threw down an inconsiderable sediment 

 which was viscid, more of a yellowish tint than the supernatant 

 fluid, and consisted of epithelium-cells and mucus-corpuscles. 



The fluid had an acid reaction, but contained neither free 

 hydrochloric nor acetic acid. Its specific gravity was 1006. 

 On the addition of nitric acid it first became blue, and after- 

 wards of a beautiful carmine red. It contained no albumen. 



In 1000 parts there were contained : 



Water ..... 990-50 



Solid constituents .... 9-50 



Fat . . . . 0-24 



Water-extract . . . .1-30 



Biliverdin with a little biliphsein and a trace of! .00 



alcohol-extract . . . ./ 



Fixed salts .... 3'75 



The salts consisted for the most part of the chlorides of 

 sodium and calcium, associated with less quantities of phosphate 

 of soda, sulphate of potash, and earthy phosphates. Urea and 

 uric acid were sought for without success.
