Leptandra Oil. By "Leptandra" the U. S. Pharmacopoeia understands 

 the dried rhizome and root of Veronica virginica, L. (Leptandra virginica, 

 Nuttall, N. O. Scrophulariaceas). Power and Rogerson 1 ) have extracted 

 55,56 kilos of this drug with hot alcohol, thereby obtaining 19,79 kilos extract, 

 of which 2 kilos was treated with steam. The yield in essential oil amounted 

 to 0,9 g. = 0,016%, calculated as dried drug. The oil boiled between 

 120 and 160° (25 mm.); it constituted a dark brown, mobile liquid with a 

 strong, penetrating odour, and gave no colour reaction with ferric chloride. 



Limette Oil. The supplies from the West Indies have been con- 

 siderable, but the demand was equal to them, and it was therefore un- 

 necessary to make any alteration in the price of our hand-pressed oil of 

 the finest quality. As is well known, we also prepare a terpeneless lime 

 oil which enjoys great favour, especially in those countries where lime 

 juice and lime squash are popular drinks. 



Linaloe Oil. The pronounced quietness in the American linaloe oil 

 market has continued, and the importers in Hamburg have not derived 

 much satisfaction from the article of late. Owing to absence of demand 

 they have been compelled several times to reduce their quotations. It is 

 true that fewer complaints of the poor quality of the supplies are to be 

 recorded, but previous disagreeable experience has induced many of those 

 interested in the oil to operate with greater care ; and the result has been 

 a certain disinclination to make purchases. As we have already previously 

 stated, a dangerous competitor to the Mexican oil has arisen in Cayenne 

 linaloe oil, and the Mexicans will be compelled to give way still further 

 before they can emerge as victors from this competitive struggle. The 

 quantities which have been shipped from Cayenne are well worth con- 

 sideration; and taking into account the superior quality, the price is so 

 moderate that we think it necessary seriously to advise the producers 

 •in Mexico to beware in time of adhering too stubbornly to their prices 

 and thus raising up a competitor whose influence in the end might become 

 a very serious matter. Experiments in distilling Cayenne linaloe wood in 

 Europe on a large scale have had to be abandoned as unremunerative, 

 and it is rumoured that in France these experiments have resulted in heavy 

 loss. According to a report of the British Vice Consul in Cayenne, 27 tons 

 of linaloe wood were exported to France in 1908, and 265 tons in 1909. 

 So far no statistics are yet available for 1910, but it would appear that 

 at least 500 tons have been shipped, the sale of which is encountering
