Mineral Oil. 



101 Petroleum or naptha. 



Naphtha is a limpid colorless oil, which is collected in wells, or 

 pits dug into certain clay soils in Media and Persia. It is also 

 found in the European state of Parma, and is used to illuminate 

 the city of Genoa. 



A substance similar to this product is obtained during the pro- 

 cess of making coal gas, and is called coal naphtha. It is a sol- 

 vent of India rubber and is extensively used in the arts. 



Petroleum is a more solid product, produced largely in our Bur- 

 mese possessions near Rainanghong. It is burnt in lamps, and 

 used instead of tar for shipping. 



Animal Oils. 



102 and 103. Fish oils. 



The only oil of any importance which comes under the head of 

 animal oik, is fish oil, which is largely prepared on the Western 

 Coast. For the mode of preparation, see " Jury Reports Madras 

 Exhibition of 1855, page 39. 



104 and 105. Neats foot oil and oil of wax. 



These two oils are seldom prepared, the former is, however, some- 

 times used for softening leather, and the latter, which is an empy- 

 ' reumatip product, obtained by the destructive distillation of wax, is 

 used in Native medicine. 



Volatile and perfumed Oils.

 mon grass, Roosa grass, Citronelle, Bishopsweed, Cinnamon,

 known. A list of the oils, in this class which are sometimes 

 used to a small extent in Native medicine, will be found in the
