 prepared from the fruit of the Cocos Butyracea, or Mackaw 

 tree, a native of South America. The fruit is of a triangular 

 shape, yellow, and as large as a plum, and its kernel yields 

 the substance known by the name of Palm Oil. It is frequently 

 imitated by axunge coloured with turmeric, and scented with 

 Florentine Iris root. 



Palm oil forms a useful substitute for lard in the composition 

 of ointments.

For common purposes, hog's lard makes a good simple oint- 

 ment, but is apt to become rancid by keeping. The simple 

 ointment may be readily converted into a detergent, a digestive, 

 or an astringent, by the addition of red percipitate, verdigris, or 

 blue vitriol finely powdered, finely powdered alum, superacetate 

 of lead {suf/ar of lead), or a solution of subacetate of lead [Gou- 

 lard's extract of lead). The following is a very useful ointment 

 for chapped heels, harness galls, &c. 



GOULARD OINTMENT. 



Simple ointment 1 lb. 



Solution of subacetate of lead, com- 

 monly called Goulard's extract (by 

 measure) 3 ozs.

 add the oil, then let it be removed from the fire, and stir in the 

 Goulard's extract : continue stirring until cold.
