■y. I stall otily add, That 1 gave füll Warning to observe whethcrthe Light in my cwo Instances had any Blevotjh or Grenijh Ttnhlure j allthat saw both, affirmed the Light to be as Ciear as the Brightest Moon-shine,and lo it appeared to my ownEyes;and I can perfectly Remember,tbat<I reallythought the Beams which came from the Mackrel, and the Stirred Pickle,to be Bright Moonfinne, till a Servant brought me to the Veßel, to see thecontrary.
Postscript. We had a Report (whethcr True or false, you may best know)of Shining Bees in the Strand , about the fame time, when the Neck of Ved,Erst mcntion’d, Shined Here. And it was here Obscuved, that the Starsbad a Glaring Brightnesi and Largeneß, more than Ordinary, and for someMontis bcfore, and ever since, the Weather hath been more Gentle, Warm,and Dry, than is Usual in these Montis ; but 'tis above my sicili to demon-strate, how this belongs to the matter in band. Note, that the Mackrel-Pickle was. Thick and not Transparent, till it was Stirred and Flaming othe Ptrk Pickle was Ciear, or Transparent, yet Sbined not in any part.
o'servxtiöns « VII. The things, wherein I observed a piece of Shining Wood and abulccsMiDf- Lttming Cod to Agree or Refimble each other are principally these Five.fntncis btrween Both of them are Lumtnaries , that is, give Light as having it (if Ima y f?eak ) Reßding in them , and not like Looking-Glaffes or Witte Bodtcs,wood ; ty Mr. which are Conspicuous only by the Incident Beams ot the Sun, or some 0-*° 3 b 1 .

This is evident, because both Shtning Wood and a Buming Ceal ShineResembiafices. t p e ^ore Vividly, by how much the Place wherein they are put is madethe Darker , by the careful Exclusion of the Adventitious Light.
2 . Both Shining Wood and a Buming Cod need the Presence of the Air ,fand that too of socha Denfity,') tomake them Continue Shining.
Tbis has been proved as to a Coal, by what I lang since publifhed inVii- Vii 11. my Phyfico Mechanicd Experiments: And as to the Shining Wood , the Ex»Scct. Lxxvi. periments I have lately scnt you, make it ncedleß for me to add any otherproof of the Requisiteneß, not only of Air, but of Air of Jucha Thicknefis ,to make its I tgbt Continue.
3. Both Shining Wood and a Burntng Cod, having been Deprived for atimc of their Light, by the withdrawing of the Contiguous Air , may pre-sently recover itby Letting in Fr^st Atr upon them.
The Former part of this, particularTryals have often sliewnyou to beTrue, when KinMcd Coals, that kern to be Extinguißit in our ExhaustedReceivers, were presently Revived, when the Air was Restored to them:And the Latter part is abundantly Manifest by the Experiments above men-tioned.
4. Both a Sfitick Coal and Shining Wood will be easily Quenched by Wa-ter and many ether J ityuors.
TheTruth of this, as to Cods, is too Obvious to need a Proof, andtherclore I stall confirm it only as to Wood ; For which purpose you maybe plcafed to cake the following Tranfcript of some of my Notes about Light.
