without change. All imports of oil of high percentage found ready 

 buyers, and the quotations were kept above 3/6. If the consumption 

 should show any considerable increase in the course of the present 

 month, higher prices will rule. 



Celery Oil. An oil from the herb and seed of the wild celery 

 [Ache des marais) which had been distilled in the South of France 

 and was sent to us from that country, was of a pale yellow colour 

 and had a pronounced odour of celery. It possessed the following 

 constants: d 15 o 0,8713, « D -|- 58 30', n D20O 1,47715, acid no. 1,8, 

 ester no. 41,5. No clear solutions could be obtained even with 

 95 per cent, alcohol, the reason of this being that the oil, which 

 was distilled last year, had become considerably resinified in the 

 meantime. After rectification with steam (in the course of which process 

 a residue of 7,7 % remained) its properties had undergone considerable 

 change: d i5 o 0,8541, a D+7° 55'> n D20° 1,47489. Soluble in 6 vols, 

 and more of 90 per cent, alcohol with slight turbidity. 



Chamomile Oil. As is well known, there are plants of which 

 the different parts contain essential oils of different composition, although 

 all the oils are formed in schizo-lysigene cells, and are therefore built 

 up in a similar manner (as for instance in the case of Citrus Aurantium). 

 In the chamomile flower, however, essential oil is formed in two entirely 

 different parts, which differ from each other with regard to the oil 

 cells. This fact has been taken by A. Jama 1 ) as the starting point 

 of a study on the essential oil of chamomile. 



The hollow calyx contains, at the part where the leaves are attached, 

 a wreath of collateral bundles of cells, and in front of the phloem of 

 these are schizogene structures containing a secretion. The fruit-whorl 

 and the stem of the flower is provided with hairs which secernate oil. 

 These hairs consist of two rows of cells, showing the characteristic type 

 of the glands of the Compositse. In both containers, owing to the 

 position of the secerning cells, the oil is formed centrifugally. 



Jama has distilled both oils separately. From 4 kilos pure flowers 

 he obtained 14 g. oil = o,35°/ and from 1 kilo of pure calices 5,1 g. 

 oil = o,5i°/ . The oil from the flowers possessed the familiar deep- 

 blue colour, while the oil from the calices was faintly green, and turned 

 yellow in the course of a few days. At ordinary temperature both oils 

 were viscous. Jama found them to possess the following constants: — 



Flower-oil: di 5 o 0,954, <* D ± o°, n D21 o 1,363734, sap. no. 74,4. 

 Calyx-oil: d 15 o 0,949, « D ± o°, n D21 o 1,363716, sap. no. 33,7.

 source of supply of this oil, it is reported that, as a result of the
