went to press the prices of 80—85% oil advanced to about 4/-, because 

 the political troubles in China were not without their effect upon the 

 article, but towards the end of the year the market quieted down again; 

 the quotations receded to about 3/10, and at that figure they have since 

 remained with slight fluctuations. On the whole the demand for cassia 

 oil has been very quiet in all the markets which count in the determination 

 of the price of the article; the consumers' requirements have been normal 

 and the supplies regular, and the balance between offers and demands 

 has been undisturbed. 



Cassie Oil. In the Philippine Journ. ofSc. 6, A. (191 1), 350, Brooks states 

 that Acacia Farnesiana, (L.) Willd. has been imported into the Philippines 

 and now occurs wild throughout the Archipelago. In his opinion it would 

 be worth while cultivating the plant for the sake of utilising its flowers. 



Cedarwood Oil. Under the heading "East African Cedarwood Oil" 

 we referred on p. 105 of our last Report to the occurrence in East Africa 

 of Juniperus procera, Hochst., a conifer which is of industrial importance 

 in the manufacture of lead-pencils. Juniperus barbadensis, L. to Which we 

 find references in two different publications 1 ) is closely related to the 

 first-named species. It occurs in the pine-districts of Dominica, and also 

 inhabits the other West Indian Islands, and the southern parts of North 

 America. So far, no oil has been distilled from this plant. Besides the 

 Juniperus-sp ecies mentioned above, Pinus occidentalism S. W., and Xantho- 

 xylum martinicense, Lam., occur in the pine-forests of Dominica.

Oil of Cedrela. F. Rabak 2 ) has distilled from the wood of Cedrela 

 odorata, L. (N. O. Meliacese), a plant which occurs in the southern parts 

 of North America, 0,3 °/o of a golden-yellow essential oil with an odour 

 of cedar. Its constants were as follow: d 25 o 0,947, n D25 o 1,5038, acid v. 3,9, 

 ester v. 41,5, ester v. after acet. 51; gives a cloudy solution with 6 vols. 

 80% alcohol. 



Celery Oil. Following upon the complete failure of the celery-seed 

 crop in France, to which we have already referred, it is not surprising 

 that the prices of celery oil have undergone a proportionate advance. 

 Our present selling-price is still comparatively low, inasmuch as it is based 

 upon the cost of a few chance purchases we were able to secure, and at 

 lie current market-value of celery seed we should certainly have to pay 

 higher rates for raw material. It is to be hoped that this year favourable 

 weather will prevail and assure a normal crop of celery seed, for if this
