Acetic acid was identified in the final aqueous solution, from which the 

 methylethyl acetic acid had been extracted by acidifying with sulphuric acid and 

 distilling until about one-half of the solution had passed over. Tlie distillate 

 contained 0.150 gram acetic acid. Formic acid was not found. 



TODDALIA ASIATICA (L.) KUEZ (t. ACULEATA PEES.). 



D. Hooper ^- describes the oil distilled from the leaves of this species 

 as having a pleasant odor resembling verbena or Basilicum. According 

 to Gildemeister and Hoffmann/^ the oil has a value as a low-priced 

 perfume oil. Isij results with the oil distilled from the leaves show that 

 it can not profitably be distilled here. A camphor-like compound melt- 

 ing at 96.5° to 97° was obtained from the oil. 



The leaves yielded 0.08 per cent of oil by steam distillation. On freezing, 

 the oil deposited 18 per cent of a white crystalline, very volatile compound, having 

 an odor closely resembling that of camphor. After recrystallizing the substance 

 twice from petroleum ether, the melting point was 96.5° to 97°. The compound 

 is very unstable. A pure specimen of it changed in 24 hours to a pasty mixture 

 of oil and imchanged crystals. It was not further investigated. The oil had 

 an odor suggesting a mixture of camphor and lemon glass. Its constants were 



as follows; 





1.4620; specific gravity, ?2! 0.9059. 



The oil is largely linalool, since the fraction boiling from 195° to 200° 

 yields citral on oxidation with chromic acid mixture. 



THE ESSENTIAL OIL OF CLAUSENA ANIStTSI-OLENS ( BLANCO ) MEEE.^* 



A quantity of leaves, weighing approximately 16 kilos, were distilled 

 with steam over a period of about five hours and 185 grams of colorless 

 oil were obtained. This oil resembled the fresh leaves -in odor and pos-
