of elimination of the hydrocarbons, this is only. achieved at the expense of the aroma, 
which, properly speaking, ought not to be sacrificed to solubility. For this reason 
Parry prefers the ordinary terpeneless lemon oil to that which has been freed both 
from terpenes and from sesquiterpenes. 
Eucalyptus Oil. The advance in price to which we referred in our last Report, 
and which was the outcome of the shrinkage of the previously large stocks held on 
the European markets, has brought about a persistent animation in the trade in 
Globulus-oil with a high percentage of eucalyptol. Large parcels changed hands at 
rising prices, because the pressure was removed which had previously been exerted 
upon the market by the existence of large supplies, especially in London. Only quite 
lately has the tone become a little quieter, as the result of a few large arrivals from 
Australia, which proved, notwithstanding the high prices realized by them, that no 
shortage of oil is to be feared, in spite of the assertions of certain speculators. The 
quality of these newly-arrived parcels was satisfactory throughout; they contained, in 
part, over 85 p.c. of eucalyptol. The ordinary Australian oil of Amygdalina-character 
has undergone no alterations in price whatever; the supplies are equal to the demand. 
We gather from the annual report of the Biological-Agricultural Institute at Amani 
for 1%* April 1912 to 318t March 1913*) that of all the eucalypts planted there, Hucalyptus 
citriodora, H.maculata, E.resinifera and E.amygdalina have made the finest growth. 
E. corymbosa, E. robusta, E. goniocalyx, EH. microcorys, H. paniculata, E. rostrata, EH. melio- 
dora, E. salubris and E. pilularis, also made good wood. , 
J. Elgart?) has made a control-test of Milne’s method of eucalyptus treatment?®) for 
scarlatina and measles, which consists in rubbing the whole body of the patient at 
the beginning of the illfiess with eucalyptus oil. Elgart found this treatment to be 
extraordinarily suitable as a prophylactic in scarlatina and measles. It reduces 
the mortality as well as the number of serious complications. Elgart has modified 
Milne’s method by concentrating the therapeutic treatment upon the disinfection of the 
breathing-passages, the gate of the entry of the disease. He recommends a ‘combi- 
nation of the two methods.
