Details as to assortments and lots of sandalwood to be exposed for 

 sale as above in each kotie, together with the terms of sale, will be 

 published as usual about the end of October 1912. 



We set forth below the analytical values of four samples of sandal- 

 wood oil which have been submitted for our opinion. Of these, No. 1 does 

 actually correspond to an East Indian Oil, but, as further investigation 

 showed, it was abnormal to this extent that it contained terpin hydrate. 

 As up to the present this body has not been observed as a normal con- 

 stituent of East Indian sandalwood oil, and could not be found in a distillate 

 of our own which was examined for purposes of comparison, it must have 

 been added to the sample in question. If the oil has not been deliberately 

 adulterated, the terpin hydrate may have got into it by some mistake. 



Sample No. 2, which was emptied out from sandalwood oil capsules, 

 was suspect on account of its insolubility in 70 p. c. alcohol, its excessive 

 ester value and its exceptionally high santalol content. After being distilled 

 by steam the sample, in addition to a normal solubility and increased 

 optical rotation, showed a diminished ester value and a reduced santalol 

 content, and then agreed with a normal sandalwood oil. The distillation- 

 residue (7,8 p. c.) was liquid, soluble in alcohol, insoluble in light petroleum, 

 and gave sap. v. 173,4, from which characters it was identified as castor oil. 



Sample No. 3 was shown to be a highly-adulterated product by its 

 altogether abnormal constants, and by its santalol content, which was 

 only 51,3 p. c. 



In the last oil-sample of our table, of which only a few grams had 

 been sent to us, we were able to detect the presence of about 30 p. c. of 

 spirit, while furthermore the optical rotation of the oil when freed from 

 alcohol was found to be much too low, and thus pointed to an additional 

 form of adulteration.
