CORRESPONDENCE OF RAY. "*93 



gratitude : and yet Mr. Fisher would esteem it an exceed- 

 ing great honour if he would condescend so much as to 

 instruct him in anything. I thought it convenient to let 

 you know that, although the account I gave you of draw- 

 ing spirit of wine out of vinegar was all that either you 

 or I received from Mr. Fisher, yet he tells me that it is 

 not the best way (and saith he told you as much), nor 

 the way that he useth ; which, for several reasons, he yet 

 keeps as a secret. He is busy at present about improv- 

 ing an experiment he hath lately made of turning the 

 whole substance of vinegar into an urinous spirit. He 

 let rue see about half a pint that he had already done, 

 which, both for taste and smell, was like a middle sort of 

 spirit oT*hartshorn. He is endeavouring to turn the 

 whole substance of vinegar into spirit of wine, and saith 

 he hath hopes of good success. I should be very glad to 

 see you here in your return from Chester.
