145. By what means this was efFeded, we are not informed by 
the afore-cited Author, but the Learned Thomas yllknVi. A, of 
Glocefter-hall^ thought it might be done by a fort of Looking-glafs^ 
whofe ftrudure he found mentioned in an ancient MS, l>e Arcank 
iStSiCYttU^ with this Title, Speculum in quo una vifu apparebunt 
7nult<£ imagines moventesfe. To be made thus, accipe fixiJem bene 
profundam^ isr pone in fundo ejws (j^eculum commune^ fc, convexum^ po- 
fiea, isfc. Take, fays the Author, a deep box^ and place in the bot- 
tom of it a common convex glaj^^ then take 6 or j other convex 
glajfeso^ the fame bignefs, and fcrape off the lead {^plumbum is 
the word] in the concave part with a knife ; where by the way the 
Author advifes, that fince it is very hard to get the lead clean off 
without breaking the^/(^/j, that^i^fc^-T/Zz/er be made ufe of, to a- 
noint the lead to get it off. 
14.6. Thei^e glaffes when made clean^ he orders to be put into 
the box^ fo as they may ftand obliquely in divers pofitions, in this 
manner : When the firft glafs is put in the bottom, the fecond 
muft be fo put, that one fide of it muft t9uch the firft glafs^ and 
the oppofite fide be diftant from it an inch, is" fie (f^ys he) oblique 
pones in pixide. In the top there muft be put one cleanfed glafs as 
the firft, plain and not obliquely^ fo that nothing muft be feen but 
the uppern: oik glafs, into which if you look, you ftiall fee as many 
Images 2iS glafes and if turned round, how one Image Awz^^ 
ftandsftillin the middle, and the reft run round it, as if they 
went about to dance. Of which cow/riz/^^wce, though I underftand 
not fome particulars, yet I thought fit to mention them, becaufe 
they may pofTibly meet with a Reader that may, and tranflate them 
too as well as I could, for the benefit of them all. As for thofe 
that have opportunity, and are defirous of feeing the Latin Copy, 
they may find k'lnz Mifcellaneou^ MS. in Mr. Seldens Library'. For 
j my part, all that I can add concerning it, is, that I have feen a 
' fort of Cabinets of this nature, that by the help of glajfes placed 
obliquely have (liewn fuch prety profpeSls.
