Basing the study on an analysis of the results obtained in 160 routine determinations of the amino-acid nitrogen in the blood of 120 subjects, mostly patients with miscellaneous pathologic conditions, an attempt has been made here to correlate the abnormal findings with any diseases with which they might consistently be associated. With reference to conditions in which other investigators have found high figures for the amino-acids of blood, our cases were grouped for separate study in order to show at a glance what our findings have been in these conditions. Finally, the tabulation was studied with a view to ascertaining a possible relationship between retention of urea nitrogen and accumulation of amino-acids in the blood. A small group of amino-acid nitrogen readings from fluids other than whole blood is appended.
Folin,1 in a group of twelve normal young men, found the average value of amino-acid nitrogen in whole blood to
