474 DR ANDERSON ON THE DISTILIATION OF ANIMAL SUBSTANCES. 



The presence of aniline in bone-oil I have already alluded to, and its quantity, 

 though small, is by no means inconsiderable, when compared with that of the 

 other bases. I did not think it necessary to take any further means for its iden- 

 tification than its highly characteristic reactions with chloride of lime and nitric 

 acid. 



Tlie investigation of the other bases is not yet in a sufficiently advanced state 

 for publication. The sparingly soluble one has been especially troublesome, and 

 its purification is attended by diflRculties which I have not yet fuUy overcome. 

 The consideration of these will be taken up in the second part of this investiga- 

 tion.
