in 70% alcohol. From the low santalol content it may be inferred that 

 the adulterant constituted about one-third of the oil. 



From a note in The Chemist and Druggist [79 (1911), 612] we also 

 gather that in the adulteration of oil sold in the form of capsules the 

 residues of santalol manufacture are being used as well as West Indian 

 sandalwood oil. The principal market for capsules thus adulterated is 

 said to be Australia, where the capsules are sold at prices barely covering 

 the cost of the oil. Several samples recently examined had the following 

 characters: di 5 o 0,962 to 0,966, « D + 8° to —4°, insoluble in 10 vols. 

 70°/o alcohol. 



Sandalwood Oil, West Indian. In this article also there has been 

 no excessive accumulation of stocks during the past few months. It is 

 true that heavy consignments of wood have reached us regularly, but the 

 demand has kept a fairly equal pace with the production, while large 

 orders from the United States kept the deliveries at a steady level. At 

 present the prospects remain unchanged, but there have lately been many 

 rumours of difficulties in transport in Venezuela, and it is possible that 

 ultimately, as a result of such difficulties, the wood may become dearer. 



Santolina Oil. This oil, which was described in our last Report 

 (p. 108), has already been examined in the same year by L. Francesconi and 

 P. Scaraffia 1 ). The authors, by using the reagents which they had already 

 employed on previous occasions, viz., osmic acid, ferric chloride solution and 

 dilute alcoholic "Soudan-IH" solution (see p. 31), discovered the essential oil 

 to be principally located in the epidermic tissues. The yield varied from 

 0,198 to l,15°/o according to the stage of development of the plant, being 

 highest shortly before the flowering. The constitution of the oil likewise 

 varies according to the period of maturity of the plant. The average 

 constitution of the oil was C 81,68° o, H ll,28°/o, O 7,04 °/o, and its 

 average constants as follow: di 5 o 0,8732, [«] D25 o — 11,74°. The first frac- 

 tions contained a terpene (b. p. 165 to 170°) and probably a phenol ether. 

 With hydroxylamine hydrochloride the oil yielded an oxime and a hydro- 

 xylamine oxime. The corresponding ketone, which Francesconi and Sca- 

 raffia call santolinone, they regard as zJ lC7) -menthene-2-one. The hydro- 

 xylamine oxime melts at 190° with previous softening at 180 to 185°.
