possibility of developing an industry in this connection. — Abstr. 
Ibid., p. 623. 
The Bureau of Plant Industry reports that the fresh leaves and 
twigs of trees grown in Florida contain from 1.0 to 1.5 per cent of 
camphor. — Ann. Rep. Dept. Agriculture, 1905, pp. 149. 
Gehe & Co. report that crude camphor was difficult to obtain and 
that, for a considerable period of 1904, practically no crude material 
was being exported from Japan. They also discuss synthetic camphor 
and outline the several methods that are being developed for its pro- 
duction. — Gehe & Co. Handels-Bericht, Dresden, 1905, p. 15. 
An abstract, discussing the value of camphor trees, points out that 
every part of a camphor tree, even to the leaves, contains camphor. 
Among the by-products are crude camphor oil, white oil, red oil, and 
a turpentine which is obtained from the white oil. — Pharm. Era, 
N. Y., 1905, v. 34, p. 127. 
Francis, John M., asserts that we have not, as yet, reached the era 
of successful camphor manufacture, but that it is only a matter of 
time and that, therefore, the subject of proper identification tests 
should receive attention. — Bull. Pharm., Detroit, 1905, v. 19, p. 363. 
Kremers, Edward, gives an account, with illustrations, of the 
method of collecting and marketing Borneo camphor. — Pharm. Re- 
view, 1905, v. 23, p. 7. 
An unsigned article describes the several methods now known or 
being developed for the synthetic production of camphor. These 
are designated as: 1, Portchester Chemical Co.’s process; 2, J. C. 
Richardson’s process; 3, E. Schering Chemical Co.’s process. — Bull. 
Soc. Roy de Pharm. de Bruxelles, 1905, v. 49, p. 136. 
Sautermeister, C., presents a discussion of the chemical constitution 
of camphor and reviews the attempts that have been made to produce 
it synthetically. — Sudd. Apotli. Ztg., 1905, v. 45, pp. 353-355, 361-363. 
Richardson, J. C. (Chem. and Drug., v. 65, p. 850) discusses the 
prospects of synthetic camphor. He concludes that the synthetic 
product can only compete seriously when it is possible to make a con- 
siderable reduction in the price of the crude material and cheapen the 
cost of manufacture. — Schimmel & Co. Semi- Ann. Rep., 1905, Apr.-l 
May, p. 118. 
Gossling, W., reviews the work that has been done in connection 
with the synthetic production of camphor. — Pharm. Post, Wien, 1905, 
v. 38, p. 599. 
Brandel, I. AY., presents some observations, from the current liter- 
ature, on the source and composition of camphor oil. — Pharm. Re- 
view, 1905, v. 23, p. 380. 
Schimmel & Co. discuss the addition products obtained from the 
safrol of camphor oil, and the behavior of these addition products
