1746.1 T0 JOHN BARTRAM. 355 



I am sorry you hath not received the books I hath send to you : 

 wherefore I send to you another copy of the Characters of 

 Lixn^us ; and an edition of the Systema Natural in octavo, 

 which is very convenient for the pocket : besides, two copies of the 

 New Chimney, translated into Dutch, of which you will be so kind 

 to send one at an occasion to Dr. Coldex, who hath been so kind 

 to communicate that book, in English, to me. That invention 

 hath found a great applause in this part of the world, which is the 

 reason that I could not hinder to let it be translated into Dutch. 

 and no doubt soon into French. In the plate, you shall see a little 

 alteration, what is occasioned by very skilfull people. 



I send also a copy of my Index Lapideai ; but at present my 

 collection is three times larger, so that I think for a new edition. 



All things you send to me came very well over, except the two 

 fishes, which were spoiled. I take, therefore, the liberty to com- 

 municate to you two prescriptions ; of which one is a varnish that 

 preserves the fishes, and any other thing, in a great perfec- 



tion, viz. :

The other is a powder, by which any creature, as quadrupeds 

 and birds, are preserved and become very hard. I have several 

 times made the experiment with a fowl, larger than a duck, putting 

 him, with his excrementse and all, into a box, which is well closed. 

 and putting this dose of a powder all over it : when the creature 

 became in few weeks very hard.

I don't doubt it will do very well with the fishes, without taking 

 the intestines out of them, except they may not be too thick [or 

 large] ; then the intestina must be carefull (by a gentle hole, made 

 in the mids of the belly) taken out. 



I hope you received my letter dated in April, 1745, by Mr. 

 Schoemaker, to whom I pray my service : likewise to Dr. Colden,
