40 REPORT OF SCHIMMEL & Co. APRIL 1914. 
said that he is able to smell this when an incision has been made into the tree, and 
no tree is allowed to be cut down until he has made sure that it contains camphor 
crystals. The preparation of camphor is very complicated, and a simplification of 
the process would be very welcome. > 
It would appear to us that the writer of the above article has confused Borneo- 
camphor with Laurel-camphor. . 
Canada Balsam Oil. A sample of Canada balsam received by us from Quebec 
(4 + 5°25’; npw20 1,52412), when distilled with steam, yielded a colourless oil, with an 
aroma resembling that of oil from the cones of Abies pectinata. Its constants were 
as follow: diso 0,8614, “p — 30° 36’, np»0 1,47809, acid v. 0, ester v. 3,7, soluble in 
3 vols. a.m. of 90 p.c. alcohol. We only record the values here because Canada 
balsam oil is one of the less-known oils. 
Cananga Oil. Business in this article has lately been very quiet indeed, although 
it has been possible to restore the prices to a reasonable level. The arrivals are not 
too heavy and the sales have moved within commensurate limits. We are, as always, 
in a position to supply our customers with the best quality at the lowest market prices. 
Cananga oil is produced in two localities: it comes either from Serang or from 
Cheribon. Most of it comes from the first-named place; the Cheribon oil is not so 
well-known. Its quality is equally good as that of the oil from Serang, but its odour 
is somewhat sharper or, to express it more accurately, somewhat more penetrating, 
a property which is preferred by some buyers, while others do not appreciate it so 
much. We only mention this because oils of this kind have lately repeatedly been 
seen in the market. We have not, however, met with any adulterated oil. 
At Buitenzorg*) cananga oil has been found to possess the following characters: 
diso 0,9061 to 0,916, sap. v. 10,3 to 25,2, sap. v. after acet. 47,7 to 67. All the samples 
were soluble in one-half their vol. of 95 p.c. alcohol. 
Cape Oil. ‘Cape’ leaves, from which Roure-Bertrand Fils*) some time ago 
prepared an essential oil with a pleasant odour, have been subjected to a thorough 
botanical examination by E. G. and A. Camus?). The leaves were found to be derived 
from an as yet unknown species of Popowia (N. O. Anonacece), to which the authors 
have given the name of P. Capea. Popowia Capea, E. G. et A. Camus is a small, creeping 
shrub which occurs exclusively in the dense forests of the eastern part of the Ivory 
Coast, in the Attié and Agnis regions. Even there it is somewhat rare. It is a remark- 
able fact that, as a rule, the fruits contain no seeds, because almost invariably they 
are transformed into galls by the stings of insects. Only a restricted use is made of 
Popowia Capea on the Ivory Coast. A parcel of dry leaf and stalk weighing about 
200 grams costs locally 20 cents, and in the markets outside the growing-district the 
price is much higher still. For purposes of use, the raw material, consisting of the 
stalks and leaves, is first coarsely broken up and then macerated with cold water. 
The extract thus obtained is then used in the bath without further preparation.
