Distillate of 1904 from French carrot seed (yield 0,5 °/ ); 

 d 15 o 0,9117; « D — i8°i8'; acid no. 1,24; ester no. 51,93; ester no. 

 after acetylation 95,7; not completely soluble in 10 vol. 80 per cent, 

 alcohol; soluble in 0,4 and more vol. 90 per cent, alcohol; in this 

 case rasped fruits had been distilled. 



We are unfortunately not in a position to state whether the 

 differences in the oils are due to differences in the uniformity of 

 the material, or in the age (prolonged keeping?) of the fruit, or 

 solely to the origin. 



Cassia Oil. The quotation of 5/6 per lb. cif. mentioned by 

 us in our last Report for 80 to 85 per cent, oil, has still been 

 exceeded in the course of April. The prices reached their highest 

 level with 6/- cif., and since then they have moved with slight 

 set-backs down again to about 5/7. At such quotations the demand 

 was naturally limited to cover only the most pressing requirements, 

 and as the supplies have lately come in somewhat more freely, we 

 think that a decline in the market is not improbable. But in 

 the case of these Eastern products we are too much used to 

 surprises, not to know that this opinion must only be regarded as 

 the expression of personal sentiment. From the producing districts 

 no fresh reports have come to hand. 



Champaca Oil 1 ). In our Report of October 1906, p. 23 we 



mentioned that, after many fruitless attempts, we had succeeded in 

 discovering again a certain source of supply for oil of champaca 

 blossoms. The manufacturer of this oil, Mr. Anderson, chemist 

 at Pasuruan, Java, when visiting us in September last year, gave 

 us some interesting information on the origin of this rare oil. According 

 to him, the oil is obtained from two different Michelia species, of 

 which one produces white, and the other yellow blossoms. For the 

 purpose of distillation white blossoms are chiefly used; they are sold 

 by the piece, and give a yield of o,oi25°/o oil. According to 

 C. L. Blume, Flora Javae, the white blossoms belong to Michelia 

 longifolia, whilst Michelia Champaca bears yellow blossoms. As the 

 two kinds of blossoms are not distilled separately, the oil supplied 

 to us by Mr. Anderson is, as he himself informed us, a product 

 which consists chiefly of oil from Michelia longifolia, and to a less 

 extent of oil from Michelia Champaca. 



As to the chemical composition of oil of champaca blossoms, 

 nothing is yet known; for this reason we have commenced a detailed 

 examination of the oil, the results of which are mentioned here.
