Dl BENZYL CAEBINAMINE. By W. A. XOVES. 



[ABSTRACT.] 



[Published in the American Chemical Journal, 14, 225.] 

 Di-benzyl carbinamine was prepared by the reduction of the oxim of di- 

 benzyl-ketone by means of sodium and absolute alcohol. 



The new base melts at 47° and boils at 330°. The chloride, Cj ■, Hj , NH2. 

 HCl, separates in compact crystals which melt at 205°. The chloro-plati- 

 nate, the nitrite and the di-benzyl carbinamine sulphocarbamimate of di-

benzyl carbinamine, q h^^ NH HS-^^^' ^^^^ ^^^° prepared. 

 B Especial interest attaches to the nitrite which is stable at ordinary tem- 

 peratures, and a dilute solution of which can be boiled with very slight de- 

 composition. In these respects the base is intermediate in its properties 

 between the "alicyclic" bases of Bamberger and the ordinary aliphatic 

 amines.— [Rose Polytechnic Institute, Dec. 1S91. 



The character of well waters in a thickly popllated area. By W. 



A. No YES. 



[abstract.] 

 A table was shown giving the results of the analysis of a number of well- 

 waters taken from wells in various parts of the city of Terre Haute. The 

 amounts of free and of "albuminoid" ammonia in these well waters is us- 

 ually very low, but the amounts of chlorine and of nitrates, and especially 

 the latter, when compared with the amounts of the same substances found 

 in a well water in the country east of the city show that the waters of the 

 city wells are seriously contaminated with surface drainage. The fact that 

 a large proportion of the cases of typhoid fever and of dysentery (477 cases 

 out of 500 cases investigated) occur in families where well water and not 

 hydrant water is used for drinking purposes justifies the condemnation of 

 such well waters, even where the amount of organic matter in the water is 

 very small.— [Rose Polytechnic Institute, Dec. 1891.
