Mr. Wray to Mr. Lifter. 



Dear SIR, 



I Return you molt hearty Thanks for the Pains yoti 

 took in perufing my Catalogue, and for your 

 Animadverfions and Obfervations thereupon. Your 

 Opinion grounded upon Experience, that Opium and 

 all Opiates are highly venereal, if taken moderately, 

 I willingly embrace. The Reafon which induced 

 me to fublcribe to the common Opinion, was not be- 

 caufe I imagined them to be cold, as the former Phy- 

 ficians fondly conceited, but becaufe they do in a 

 large Dole fix the Spirits, and inhibit their Motion, 

 as appears in that they are Anodynous and Soporife- 

 rous y and the Sperm being a fpirituous Body, I was 

 thence induced to think that they might hinder its 

 Turgefcency. But, upon farther Confideration and 

 Enquiry, I find the Effects of Opium to be fomething 

 analogous to thofe of Wine, and other generous Li- 

 quors $ which, moderately drunk, incite to Venery, 

 but to Excefs, become foporiferous and narcotick, 

 extinguifhing that Appetite: Whence it is fuppofed 

 to proceed, that the Germans are of all Nations moft 

 continent, and leall addided to Women. I thank 

 you likewife for your Note cut of Oiearius concern- 

 ing Hemp, which I have now entred. I intend to 

 follow your Advice, in adding fomething to my Pre- 

 face concerning the Ufefulneis of being particular 



and
