malis, vel ejus tectum et domicilium representant, quales Petri- 

 FICATA appellare eonsueverunt authores, quceque in veritatem dilu- 

 viance inundationes adducere non dubitarunt. Hcec vario sita 

 loco observavit vir egregius [Joannes Bartram] ; alia quippe in 

 superficie terrce, alia in prof undo. Quce enim in Australi [?] 

 Pensilvanice plaga, immensos Canada? lacus resjnciens, occurrebant, 

 in superficie terrce jacebant: imo in itinere, quo aliquot centum 

 milliaria absolvit, ea ubique sparsa reperit.* **** 

 And in this way I propose to go on with every particular subject 

 you send me. In things now which are extra sphceram ?neam, I 

 address niyselv to such gentlemans, which I know that have any 

 notion of them. You never can believe how our Virtuosos are 

 pleased to see the cells of the Wasp nests filled with Spiders, of 

 which they never have heard before. Professor Muschenbroek 

 and Luiiots cannot enough admire that mechanica. They hope 

 with me to give you a good account of it ; only we wish you could 

 sent to us at an occasion one of the Humble Bees himself, and also 

 one long, blac Wasp num. 25 and 26. We have discovered, that 

 all the chrysalides of them, and those that are still in their silk 

 folliculus are still in life. So that you see by this way everything 

 will be welcome. 



Pray, can you tell me how goes the Loadstone Rok, out of 

 which you split the Cotton Stone, num. 6 ? Doth she go from 

 east to west, or from south to north, or else way ? You send to 

 me a shell with a sort of a Lapster in it. The shell is the Cochlea 

 perlata Bonan. rar., class 3, num. 167. The animal in it is the 

 Heremite Krab of Catesby, Nat. Hist., vol. 2, tab. 33, fig. 2, the 

 Soldger of Rochefort, p. 122. * * * But the paper wherein 

 it was involved, was inscribed with the name of Antiqua. I wish 

 to know if this is the Indian name. It will be very convenient 

 always to have the Indian names. As much as possible you 

 must endeavour of the conchas bivalves to get both the valves. 

 You never can belive what a great rarity there is amongst the 

 muscles num. 1, and particular amongst the small ones, of which I 

 find severall different varietys. I belive upon strik enquiry, that 

 in your sea and rivers, are to be found all the species of Conchas 

 and Cuchlece, which are to be found everywhere ; for I see that 



* For a translation of this passage, see Doctor Colden's letter to John Bar- 

 tram, under date of May 9, 1746, page 331. The word "Australi" is evidently, 

 as Doctor Golden suggested, a mistake for Boreali.
