Santal-wood oil, estimation of. An examination has been 

 made by Cripps* of several samples of santal-wood oil and cedar- 

 wood oil. A table of colour-reactions is given, the most important 

 of which are those with nitric acid, and hydrochloric acid and 

 chloroform, the former giving a green tint with cedar-wood oil and 

 the latter, a pink coloration in the acid layer, which are not 

 produced by the different kinds of santal-wood oil.
