 rectified colourless; thin; smells like the fruit; of 1'01-1'04 density; 

 solidifies between 2° and 8°; boils between 160° and 170°; dissolves

 alcohol, under the form of colourless and inodorous, highly 

 shining, brittle prisms. The oil of the leaves of C. Zeilanicum is 

 very similar to that of cloves; of 1053 density; contains caryo-

 another sparingly soluble, which is colourless or yellowish, of 

 extremely pleasant odour, of neutral reaction, of 0-85-90 density; 

 forms stearopten on keeping. — The oil of the fruit =C2o Hie, is
