ing,) lard oil has no equal. It burns with a strong white 

 light, and is entirely free from either smoke or smell. 

 It does not contain any gelatine, which makes it a prefer- 

 able article for all kinds of machinery ; for wood it an- 

 swers better than the olive oil, which it has superseded 

 entirely. The oil of tallow is also well adapted for ma- 

 chinery ; for burning it is not preferable to other oil, on 

 account of its odor. Tallow only contains about twenty, 

 eight per centum of oil, whereas lard contains on the av- 

 erage sixty-two. The stearin of both lard and tallow 

 makes a better and harder candle then sperm, and the 

 same amount in weight produces a great deal more light.
