respect of its odour, so closely allied to palmarosa oil in its properties, 

 and so cheap, that its introduction not only served to relieve a pressing 

 want, but also created a competitor of genuine palmarosa oil which will 

 doubtless have the effect of putting a check upon price-inflations on the 

 part of the producers of and speculators in the latter article. The news 

 of an abundant new crop which reached us last autumn has not been 

 contradicted and we therefore regard it as not improbable that prices 

 may recede in the course of the summer, for in proportion as the demand 

 for our Palmarosa Oil Substitute has increased, the sale of the genuine 

 oil, as compared with previous years, has declined. 



Oil of Paolo amarello. Roure-Bertrand Fils 1 ), in their last Report, 

 mention two essential oils which they have distilled from Brazilian woods 

 of unknown botanical origin. 



The oil distilled from the wood known in Brazil as Paolo amarello is 

 almost colourless and has an odour of linaloe oil. The oil-yield was 0,41 %, 

 and the oil possessed the following characteristics: d 15 o 0,8892, « D — 5° 54' 

 sap. v. 22,9, ester content 8%, calculated as linalyl acetate, ester v. after 

 acet. 200,2. It was soluble in 2 vols and more of 70°/ alcohol. 



The other oil distilled from Brazilian wood was obtained from the 

 chips of Turpentine- Amarillo, the oil-yield being 0,134%. This oil had an 

 odour reminding of turpentine, « D + 8°32', and was soluble in any pro- 

 portion in 90% alcohol. 



Patchouly Oil has remained unchanged at low prices, owing to the 

 fact that we had secured large parcels at the right time, and were there- 

 fore in a position to disregard in our price-lists, for the present at any 

 rate, the advance of about 15 p. c. which has in the meantime taken place 

 in the quotation of patchouly leaves for shipment. During recent months 

 business has been fairly considerable, numerous friends of ours having 

 taken advantage of the low quotations to cover their requirements for the 

 year, and unless the cost of the raw material should decline we may soon 

 be compelled to adjust our quotations to the position of the market. 



Pennyroyal Oil has been altogether neglected. This article is by 

 no means so important now as it used to be, having been almost super- 

 seded by other oils, especially in the soapmaking industry. At the time 

 when the scarcity of pennyroyal oil was so acutely felt, in the years 1 907 

 and 1908, many consumers began either to omit it from their recipes 

 altogether, or found it advantageous to replace it by other oils, and they 

 have since continued to employ such substitutes, the supply of which is 

 not subject to possible failure. The stocks of pennyroyal oil of all de- 

 scriptions have accumulated a little everywhere and even if prices were 

 greatly reduced it is doubtful whether the consumption could be increased.
