Then two or three strange-looking packages were handed up to them from the outside. There was a whispered discussion, and then the parties within were heard moving cautiously about and a strong benzoic odor came from the upraised window.
The speaker had, finally, demonstrated the synthesis of hippuric acid and sulphate of phenol in the excided kidney as a function of its cells, by adding to the blood pouring through the kidney, in the first place, benzoic acid and glycol; in the second place, phenol and sulphate of soda.
Because they contain essential oil; some afford benzoic acid when heated, and these have been termed balsams; such as tolu balsam and benzoin. Common resin is obtained by distilling the exudation of different species of fir; oil of turpentine passes over, and the resin remains behind. Why are the varieties of the cashew tribe, called varnish-trees?
When boiled with baryta water, sinapine decomposes into sinapic acid, C H O , and choline, C H NO , the latter a well-known constituent of the bile, and produced also in the decomposition of the lecithin of the brain and yolk of egg. Cocaine, the alkaloid of coca leaves, is decomposed by heating with hydrochloric acid into methyl alcohol, benzoic acid, and a crystalline base, ecgonine, C H NO .

The urine secreted by the kidneys is a body excretion, and consists of water, organic matter and salts.

The nitrogenous end-products and aromatic compounds are urea, uric and hippuric acids, benzoic acid and ethereal sulfates of phenol and cresol.
