C. E. Sage 1 ), while examining eucalyptus oil, has determined the 

 cineol-content both according to the resorcinol method published by us 2 ), 

 and according to the phosphate method as detailed in the United States 

 Pharmacopoeia, and has arrived at the well-known conclusion that the 

 figures obtained by the two methods do not agree. This appears to 

 us merely to afford another proof of the uselessness of the phosphoric 

 acid method, for, as shown by us from numerous examples of mixtures 

 with known cineol-content 3 ) our modified resorcinol method, when carried 

 out correctly, gives reliable values. Our experience shows that any 

 crystalline deposits (consisting of cineol-resorcinol) which may happen 

 to be present in the unabsorbed oil floating on the saturated solution of 

 cineol, are without practical influence upon the result of the test. We 

 draw particular attention to this fact, because Sage, in common with 

 others, has observed such deposits and suspects them of vitiating the 

 result. 



Fennel Oil. The fennel crop in Galicia is now proceeding, and the 

 yield may be described as a fair average one. If the favourable weather 

 which has been experienced for the past few weeks should continue, it 

 is believed that the quality will be excellent. We expect to receive the 

 first supplies very shortly, and the quality of these will determine whether 

 we shall again work up large quantities of fennel during the coming 

 winter. The prices appear inclined to recede to the advantageous level
