the residue dissolved in petroleum ether, and the soluti on agitated with 

 proof spirit ; by this means most of the colouring matter was removed. 

 The cholesterol was finally several times crystallized from petroleum 

 ether, and was obtained perfectly white. A benzoyl derivative was 

 also prepared. Evaporated with a drop of nitric acid and the dry 

 residue moistened with ammonia, an orange colour developed, but 

 no change was induced by the addition of caustic potash. The violet 

 reaction with ferric chloride and HOI applied as described by Forti 

 was very max'ked. The sulphuric acid and chloroform reaction was 

 conducted in a stoppei'ed bottle ; the chloroform layer at first became 

 yellowish-brown, then blood-red, finally darkening to reddish- purple ; 

 the sulphuric acid and sti'atum was of a pink colour, and in some 

 experiments fluoresced. (^By C, J. H. Warden, and Assistant Surgeon

LABIATE. 

 Salvia macrosiphon, Boiss. 



The Kanocha seeds referred by us (Yol. III., p. 265) to Pht/Uan" 

 thus madraspaf exists have been shown by Dr. O. Stapt to belong to 

 a species of Salvia. Dr» Stapt bought the drug in the bazaars of 



Ispahan, where it was known by the Persian name 3Iarv. A drug 

 called " Merw" was mentioned by Abu Mansur in 1055, and Selig- 

 mann refers it to Origanum Mart\ L., a native of Syria. Aitchison, 

 in his Notes on the Products of Western Afghanistan, mentions 

 '•Salvia (?)" as the origin of the nutlets known as Kanoncha or 

 Kanouncha. (Pharm. Journ,. March 11, 1893.) 



Influence of Menthol on the gastric functions,* 



Following Professor I. T. Tchiidnovsky's suggestion. Dr. \ladi- 

 mirsky has carried out a set of experiments on seven healthy subjects 

 (six men, including himself, and one woman), aged fi-om 24 to 32, 

 the drug being administered with food, in the dose of 0'3, I'O and 20 

 grammes The author has arrived at the following conclusions : 



(1) The diaig (in any of the doses stated) very markedly dimi- 

 nishes the proportion of free hydi-ochloric acid in the gastric juice^ 



the decrease attaining its maximum in about 1 or Ij hours after 



the ingestion.
