had fodryed up his Brain, that after his death there was found in his 
Head but a very fmali black clod, compofcd of fundry membrans ^ and 
yet his Soul had not been wanting to perform her fundions to the laft. 
He alfo takes occafion to difcourfe of adventuring to affirm, 
that Refpiration is caufed by divers liquors, which riling through the 
Veins into the Heart, and there fermenting, fend to the Lungs fuch Va- 
pors as attra.^ the Air : For ilhiftration whereof,he faith, That^ if to a 
Glafs-bowI,holIow and with a fmall hole, you fodder divers Pipes of 
Glafs half full of different ftrong Liquors, the Vapours, elevated from 
thofe Pipes in the glafs-bowl,will draw the Air after the fame manner as 
tis drawn into the Lungs by Refpiration. 
In the other Letter, he treats of the. way of curing fcveral Diftcrapers 
0fthe£yes,and particularly of fome furprixing ones, cured by himfelf. 
Where he affirms,that,having cut afunder the Apple of the Eye of divers 
Animals, and fqueefed out the humors, even the ChryfidUin it felf,hehath 
reftored the fight to thofe Animals and that the Eyes of thofe Birds,pn 
which he had made this Experiment,loo.ked better and more vivid than 
before-, and that he had performed this operation upon manyperfons 
with fo much fuccefs;ihat in their Eyes there remained not the leaft ap- 
pearance of a Scar* After this relation he is not ftiy to teach the way of 
making this Operatiaii^adding the cautions to be obfervcd therein, and 
withall the Remedy itfeif ^ which conlifts chiefly in a certain W^ter of 
C^/Ww^,and a Phlegme Vitriol 0^ Mars.^ •- 
Gn the occafion of teaching the Preparation of this remedy ,hc taketh 
notice of feveral particulars;pcrhap5 not to^ be defpifed : Firft, That if 
about a pint of Water be poured on ten pounds of Filings of Iron, frefli 
and fine, and^after having well ftirrM it with one's hand^you cover the 
veffel, wherein it is, and wrap it about with fome dry fluff, thefe Filings 
willjWithin the fpace of an hour and an lialf, ferment and grow hot, like 
Caix viva. Secondly , That having often quenched in Water an Ingot of 
fine Gold, heated red-hot, be hath found the weight of that Gold nota- 
bly diminiili't ^ and having afterwards fuffered the Water to evaporate, 
drawn a little Gold thence; which (he faith) fii€ws,that the moft fubtile 
parts of the Gold pafs into the liquors, wherein it is quenched ^ whence 
it is Che adds) that fuch liquors have adniirable vertues , to cure many 
DifeafcstAnd araongft others he pretends, that m Dyffenteries there is no 
l^etter Remedy, than Rofe- water, wherein Gold hath been quenched. 
Thirdly, Thatin the Refolution of Simpler^ an excellent means of pre- 
fer ving their proper virtues is , inftead of uling Fire or any other 
ftrangeHeat, which might alter their vertues , to employ only the 
Warmth of an Hot-bed made of the Putrefadion of the Herbs of the 
fame S j^ecies with ihoit you would Diftii.
