10. REPORT OF SCHIMMEL § Co. OCTOBER 1914/ APRIL 1915. 
Camphor Oil. In 1913 the camphor exports from the Chinese province of Fukien’ 
amounted altogether to 210 piculs (12694,5 kilos) whereof 207 piculs came from Foochow 
and 3 piculs from Amoy. Compared with 1912 these exports are about 1900 kilos — 
higher, but they are still far behind the average attained in former years‘). 
According to an American contemporary’) the Bureau of Forestry of the Philippine 
Government, after practical experiments extending over two years, contemplates the 
cultivation of camphor trees on a large scale. For this purpose the Philippine archi- 
pelago offers a sufficiency of suitable soil. 
Cananga Oil. Several samples submitted to us recently showed a higher ester 
value (38,2 to 42,9) than normal cananga oils, and were also of insufficient solubility, 
thus rendering them suspicious of having been adulterated with a fixed oil. After 
distillation with steam their ester value went back to the normal figure (10 to 35), 
the oils becoming clearly soluble in 1 volume of 95 p.c. alcohol; on diluting up to 
10 volumes only slight turbidity showed itself, whereas the oils in their original state, 
though of the same initial solubility, separated globules of oil on being diluted up to 
10 volumes of 95 p.c. alcohol. Moreover, divergences were observed in the amount, 
as well as in ester value, of the residues obtained in the process of steam rectification. 
Two pure oils, examined at the same time for comparison purposes, yielded distillation 
residues of 2,6 and 2,8 p.c. respectively, with an acid v. of 1,8 and an ester v. of 98,8 
in one instance, and an acid v. of 5,6, and ester v. of 66,2 in the second instance. 
The distillation residues of the two suspected oils were from 6,5 to 8,7 p.c. and their 
sap. v. from 183 to 191; from which it may be deduced that they contained small 
quantities of a fixed oil. It could not be determined whether this was a case of 
intentional adulteration, or accidental impurity. 
Cardamom Oil. E. M. Holmes’) gives the following constants for an oil dis- 
tilled, with a yield of 1,2 p.c., from Korarima-cardamoms (Amomum Korarima, Pereira): 
dis0 0,9038; a)7—3°; acid v. 3,6; ester v. 22,1; soluble in */2 volume of 90 p.c. alcohol. 
The odour differs from that of normal cardamom oil, which-possibly explains Dymock’s 
suggestion to call the Korarima cardamom “Nutmeg cardamom”. According to Holmes, 
in Gildemeister and Hoffmann’s book on essential oils, Amomum angustifolium, Sonn. 
is mentioned as mother-plant. We may point out that this only applies to the first 
edition, whereas the second edition of the work referred to correctly mentions Amomum 
Korarima, Pereira as being the mother-plant. 
A picture of Korarima cardamoms is added to Holmes’ treatise. 
Cassia Oil. As is well known, Hirschsohn’s lead acetate test*) is generally used, 
i.a., to determine colophony in cassia oil. This test is carried out in the following 
manner. To a solution of one volume of oil in 3 volumes of 70 p.c. alcohol up to 
t/s volume of a freshly prepared saturated lead acetate solution in 70 p.c. alcohol is 
added drop by drop; precipitation will be observed if colophony be present. 
According to an English contemporary*) this reaction may also be made use of 
for the quantitative determination of rosin. For this purpose 5 g. of oil are dissolved 
~ in 20 cc. of 70 p.c. alcohol to which 10 cc. (or more if necessary) of a saturated solution
