and exa£t in Natural Hiftory : But much I have not 

 to fay concerning that Point ; and I am fearful of 

 enlarging my Book, and fwelling it to a greater Bulk 

 than may commodioufly be carried about in ones 

 Pocket, for tl;at will make it unufeful, and confe- 

 quently lefs faleablc; be (ides that, it is not proper to 

 let a great Porch before a fmall Houfe. I mull not 

 forget to thank you for the Prefent you font me. 

 I agree with you, that what you feat in fmall Pieces, 

 and confequently the reft of the fame Nature caft up 

 on your Coaft of Lindfey, is Yellow Amber. The 

 like Variety of Colours is obferved in it where-ever 

 it is found 5 hnd the other great Piece is truly Jet, 

 and not Cannell. By the Leg of the Buzzard, and 

 the Defcription you formerly fent me, I am confi- 

 dently perfuaded it is the mitvus Mrugmofm Aldrov. 

 As for the Authors who have written of Minerals and 

 Foflils, I have not been fo converfant in that Part of 

 Learning as to be able to give any Judgment con- 

 cerning them. GeorgiUs Agricola de re Met allied^ £5? 

 de Naturd Foffilium^ is of all Men approved, though 

 I muft confefs my felf never to have read him ; and 

 I fuppofe Lazarus Erker y a German^ is a good Writer 

 on that Subje£t. I have run over Kircber's Mundus 

 Subterraneus^ though I mull needs fay I was not much 

 improved by it \ yet fome Ufe may be made of it. 

 Some Help it hath been to me to have feed various 

 Colle£tions of Minerals with their feveral Titles ia 

 Cabinets beyond the Seas. I am not fo cunning as to 

 tell, or give any probable Guefs, what thofe Plants 

 (hould be whole Juices you fent: Indeed I do not 

 pretend to a critical Palate, but I mull defire to be 

 informed by you. Of your Table of Spiders I lhall 

 at prefent add nothing. I doubt not but it will be 

 of great Ufe to me, when I fhall have Leifure to pro- 

 fecute that Enquiry. Since I received my Catalogue 

 from your Hands, I have procured fome confiderable 

 Experiments and Obfervations medical from Dr. Need-
