which has been expressed experimentally, but there is little ground for 

 imagining that it will ever become an article of commerce. 



Eettie Oil ; Shwet-sal, Beng. ; Viroogoodu-chawa (Dalbergia lati- 

 fblia, Roxb.) — The oil obtained from the seeds of this tree is procured 

 in but small quantities, and hence is only medicinally employed. It is 

 used principally in cutaneous diseases. 



Dalbergia arborea, Heyn. ; D. frondosa, Roxb. — This valuable timber 

 tree, which is found in most parts of India, but especially in Travancore, 

 yields seeds from which an oil is procured, and used by the native practi- 

 tioners in rheumatic affections. 



Exile Oil (Thevetia neriifolia). — The kernels of the seed of this shrub, 

 which is very common in India, yield by expression a large percentage of 

 a clear, bright yellow-coloured oil. 



Fennel Flower-seed ; Kala-jira ; Mugrela, Bengal. ; Siah daneh, 

 Pers. ; Nulla Gillikarra, Tel. ; Kulonjee, Hind. (Nigella sativa). — 

 A dark and fragrant oil is extracted from the black aromatic seeds of this 

 plant. The oil obtained in Egypt under the name of mildew oil from the 

 same source is limpid and colourless, and with but little odour. A 

 specimen from the latter locality was shown, with the seeds, at the 

 Exhibition of 1851. The oil appears to be employed in India principally 

 as a medicine. It is called Jungle geerah oil in Mysore. 



Fcetid Sterculia ; Coodiri pusjun ; Junglee Badam (Sterculia 

 foztida). — This semi-solid oil contains a great quantity of stearine. At 

 present it does not appear to be obtainable in sufficient quantities to render 

 it of commercial importance or interest. The trees from which the seeds 

 are obtained are fully 30 feet high, and grow very straight. The seeds are 

 produced in large pods, three, four, or five joined together, with a rough 

 velvet coat outside, red on the side exposed to the sun. They are in shape 

 and appearance very much like green peaches ; and within these pods are 

 found the seeds, about six in each. There is a little more labour required 

 in extracting the kernel from the seed than in castor-oil making ; in other 

 respects the process is just the same. 



The results of an experimental manufacture of oil from these seeds is 

 6tated as follows : 



Original quantity of seed 

 Clean kernel - 

 Husk and sweepings - 

 Produce of unboiled or raw oil 

 Produce of cake 

 Loss in weight - 



Four seers of the above oil were boiled to extract the water, as in 

 the manufacture of castor oil, and produced 3 - 2 seers of oil fit for the 

 market. 



Gamboge Butter ; Mukki-tijlum (Garcinia pictoria). — This solid fat 

 is obtained from the fruit of the gamboge tree of India. It is known by 



Maund.
