Samples No. 1 and 2 contained terpinyl acetate, while No. 4 was ad- 

 ulterated with glyceryl ester, which was detected by shaking with 5% al- 

 cohol. 10 cc. of the filtrate obtained in accordance with the method 

 described in our Report of April 1911, p. 150, used up 0,91 cc. seminormal 

 liquor. It was not possible, however, to identify the glyceryl acetate, the 

 sample at our disposal being too small. 



O 



L. Lamothe, to whose publications on lavender, its cultivation and 

 its distillation, we have already repeatedly referred in these Reports 1 ), 

 calls attention in an interesting article 2 ) to the fact which up to the present 

 has been but little noticed, namely the increasing cultivation and utili- 

 sation Oflavandin (Lavandula fragransXlatifolia, Chatenier). This species 8 ), 

 which is the result of a crossing of lavender and spike, is known in 

 Southern France by several other names besides "lavandin", for instance 

 "lavande batarde", "grosse lavande", "badasse", and others 4 ).

3 ) For further details see the original article, and also the same author's pamphlet "Lavande et 

 Spic" (Report November 1908, 76). Also compare A. Birckenstock, "Action de l'hybridation sur les 

 essences de lavande et aspic" (Report October 1906, 43). 



4 ) Lamothe also gives tt grande lavande" as a synonym, and frequently uses this designation for 

 "lavandin" in his article. On the other hand in his brochure "Lavande et Spic", he expressly 

 differentiates between "grande lavande" (spike), and "grosse lavande" (lavandin).
