26a USE OF BLACK OILS. 



Then add spirit of turpentine, two ounces : 

 Stir these well together until united, add one 

 pint more of linseed oil ; stir the whole toge- 

 ther, and put it in a bottle for use. 



These oils are excellent for the purpose for 

 which they are intended ; but for the sake of va- 

 riety, another recipe should be subjoined, contain- 

 ing more articles, and of a different description 

 from the former ; but which will, in fact, answer 

 the same purpose, or may even be more efficacious ; 

 and which we can confidently recommend to ge- 

 neral adoption. 



(RECIPE, No. 188.) 



Take— Linseed oil, four ounces ; 

 Oil of vitriol, one ounce ; 

 Stir them together in a large pot ; then add 

 Spirit of turpentine, eight ounces ; 

 Oil of elder, four ounces; 

 Oil of origanum, one ounce ; 

 Barbadoes tar two ounces ; 

 Compound tincture of myrrh, four ounces ; 

 Oil of bays, two ounces : 

 Mix them all together, by a little at a time, 



with the vitriol and linseed oil, and put them 



into a bottle for use. 



When either of these oils is mixed up, it 

 should not be put in a bottle too soon, and corked, 

 lest it should burst the bottle.
