the last run of the still in the manufacture of aniline. This pro- 
duct—a black tarry liquid with a disagreeable odor—was dissolved 
in hydrochloric acid, diluted and filtered. Upon addition of 
sodium hydrate, the bases were set free as a light oil swimming

volume of 21°15 ems.? of the liquid was forced through a capil- 
lary tube 300 mms. long, and ‘46 mms, in diameter, under a pres- 
sure of 158 cms. of water. Observations were made with solutions 
of chloride of ammonium of five different strengths, at intervals of 
that at low temperatures the viscosity is less, at high tempera- 
tures greater, than that of water. The same result was shown by 
H,SO,, HCl, HNO,, HC1O,, HB, and HL. In each of the three
