Dear Sir y Oxford^ Aug, z8 — $>f. 



r a 1 H E firft of your Queries was. Whether the im- 

 JL preffions be all of Leaves , or parts of Leaves ? 

 To which I Anfwer, That the Stone wherein thefe 

 mineral Leaves are exhibited , is generally fo brittle, 

 that when we endeavour to fplit it , to get out a 

 Plant, it breaks alfo tranfverfly * fo that for one whole 

 Fern-branch we find, we fee twenty broken ones, 

 but for fingle Leaves they are very cbmmon. More- 

 over, thofe Stonq$ are broken in fuch fmall pieces, 

 by the Workmen in the Pit, that we find few lumps 

 big enough for whole Plants ; and indeed if they con- 

 tained whole ones, it feems impoflible fo to fplit them 

 as an entire Plant fliould be expofed to view. How- 

 beit it has not been my Fortune hitherto to meet 

 with any other parts of Plants than either fingle 

 Leaves or Branches : Whether there be any Roots 

 or Flowers to be met with , I fhall endeavour ( God 

 willing) to be inform'd hereafter. Your other Que? 

 ftions are, Whether they are found fmooth or crum- 

 pled, and whether we meet with the impreffions of 

 each fide of a Leaf? To which I Anfwer, They are 

 always fmooth and fair, and that I have feen both 

 fides of Leaves. Nay, latbly (fince the Date of my 

 laft) I have feen both fides of the fame numerical 

 Leaf j fo that I can now confirm that Obfervation
