Para rubber contains in its native haunts 1-5 pc. albumen and one- 

 third ounce of formic acid or half ounce oi glacial acetic per gallon 

 is sufficient to coagulate it. 



In Castilloa double the quantity is required. The acid should be 

 diluted with at least 1 pint of water. 



The author recommends the use of a washing machine such as 

 is used in rubber factories. 



This is a short resume of this valuable paper which is worth 

 the attention of all rubber planters. It is illustrated with a few 

 photographs, one of which is that of a remarkably fine Castilloa 

 2 years old in Mr. Pear's Kstate at Muar.r— Editor.
