XVIL-DISTILLATION OF CAMPHOR. 



(Ginnamomum Camphora, Nees.) 



The subject of Camphor was discussed in the volume of the 

 Keiv Bulletin for 1899 ; its distillation is dealt with on p. 61. In 

 a recent communication from the Government of Madras (Revenue 

 Department, CO., 1013, dated October 10th, 1906) this part of the 

 subject has been further dealt with, and an extract from a lecture 

 delivered on May 14th, 1906, before the Ceylon Agricultural Society, 

 by Mr. M. K. Bamber, is given in full. The extract, which is of 

 value as supplementing the previous accounts of the process, is 

 now reprinted.

 and very similar to that used by the Japanese in Formosa, with 

 slight improvements in the condensers as perfect condensation is 

 absolutely essential for success. The slightest smell of escaping 

 campnor may mean a loss of 20 per cent, or more as has been 

 proved by several experiments, and the two means of preventing 

 it and obtaining the maximum proportion of camphor to oil 

 oHieat conden sation and slow distillation with a minimum
