1743.1 T0 JOHN BARTRAM. 351 



under num. 2, amongst the Salt Water Shells, you send a valva 

 cava pectinis aurit., but the other ones are the most curious to 

 my knowledge only to be found at Curacao, in the West Indies, 

 and at Amboina in East India ; they are one of the valvse of the 

 Ostrea perlata capite foraminoso Petiv. mus. n. 823, and Concha 

 suhrotiuiJa, una valva perforata, cujus multiplices sunt varietates, 

 Gualt. Ind. test. tab. 97. * * * * * 



Your consideration upon the fragments of variety of pots, num. 

 4, is really some thing news. I don't find any mention about 

 the earthen pots of the old Indians, before they were acquainted 

 with the Europeans, in our Voyageurs, except Sloane, Introd. p. 

 47 et 70 ; who, tabula 2, gives the figure of an Urna, found in 

 Jamaica. So that your pot is a great antiquity, worth to be set in 

 a public Musceum. 



I admire so many things discovered by you in Pensilvania, 

 which are the same in Germany. It brings me in mind a pro- 

 blema of the botanist, that Plantce alpince ubique ewdem ; planto3 

 ejusdem climatis fere ewdem ; and at present by your observation, 

 we may conclude, terram ejusdemque contenta sub eodem scepe 

 eadem : for num. 7, the marble of your contrey is the Stalactites 

 calcis solidce, Supell. p. 15, No. 12.

You shall very much oblige the learned world with your commu- 

 nications ; particular with your Yournal to the Five Nations. I 

 am particularly desired by some learned gentlemen to ask you 

 about the Loadstone, of which they wish to know what the longest 

 and the thikkest piece was you remember to have seen ; and if you 

 could spare, to have a little pieces of the same you send me, which 

 is the most curious they ever have seen, to make experiments 

 with it. 



As soon I have an occasion to send to Mr. Collinson some- 

 thing, I shall send to you the sheeds you want to compleat your 

 Characters, besides another copy of the Characters for a pocket- 

 book ; and another copy of my Index supellectilis. Pray, my 

 service to Doctor Phineas Bond. 



We hath here this winter, one of the Dutch ministers from 

 Pensilvania, studiing in physick. I have seen him once in my 

 house, but seeing that he was a man of no knowledges of all, I 

 would not los my time with him. 



Now, dear sir, I finish these, with many thanksgivings for so
