DURING myn absence from home, I find that the question of peptonuria versus albuminuria in connection with the tests for albumen now :on their trial, has been raised in the JOURNAL and talked' about. Before reading the article on " Picric Acid 'as -aMens af! Distinguishing Albumen from Peptone " which appeared in tbehe JOURNAL of March 31st, I had performed several .experiments on, t4ibumen and peptone, with a yiew to discriminate these bodies by the: xeagents which, last January, I introduced
more » ... uary, I introduced to professional rwtice the form of test-papers. The results of these observations will,' doubtless, Just now be intereatlig to many, who are working with these and other tests, so as to decide for themselves their Comparative range and power, and I will briefly record them.witho4t delAy, before proceeding to further inquiry. The peptone was derived from digesting at a temperaturepf 100lG,' wxth pepsina porci or pepsin-essens (Liebreich), and an' acid (hydrochloric or lactic), one or other of the following' forms of albumen: (a) White of egg boiled for half an hour, or (b) albumen purified after the method of Wurtz, (o) albuminous urine (ser-albumun)., After several hours, eight or ten, a final boil enabled me to fllter off a clear solution, which, judging from the negative results obtained by boiling and by nitric acid, was free from ordinary albumen.
