 salts of which, like the thymol sulphonates, produce with ferric 

 salts an intense blue colour, Jahns (1880) reported also the 

 presence of a little thymol and carvacrol. Messrs. Schimniel 

 & Co. (Report, April 1891 ) obtained by distillation of the leaves 

 and stalks 0-3 per cent, of an oil having a very pleasant melissa- 

 like aroma with a slight soup<5on of thyme. Its specific gravity 

 atl5°C. was 0-917, 



Thymus mlgaris, Linn., is the chief source of thymol in Europe; 

 the essential oil is usually sold under the name of Oleum Origani.

History, Uses, &C.— The Mahometan physicians of the 

 East identify this drug with the oplyavov of the Greeks, and 

 describe it as having properties similar to those of thyme and 

 mint. Dr. Jayakar of Muscat found the plant in flower in 

 May 1885 on the hills near Muscat in Arabia, and kindly 

 forwarded specimens, which were identified at Kew as Z. muUi- 

 flora. The drug is much used in India in infusion as an 

 agreeable aromatic stimulant and diaphoretic; many other
