Aliud est stannum, de quo mox agemus: et aliud plumbum candidum nostrum,

p. 62. _De Stanno._ Cap. XXXII.

"In praecedenti capite indicauimus aliud esse stannum, aliud esse plumb[~u]
candid[~u]. Illa ergo definitio plumbi candidi, dess zinnes, etia apud
chimistas n[~o] de stanno, sed de plumbo candido (ut mihi uidetur)
intelligenda est, cum dicunt: Stannum (es soll heyssen plumbum candidum)
est metallicum album, non purum, lividum...."

p. 63. "Sic uides stannum, secundum Serapionem, metallicum esse quod
reperitur in sua propria uena, ut forsitan apud nos bisemut[~u]: ec[~o]tra
nostr[~u] candid[~u] plumb[~u], est Plinij candid[~u] plumb[~u], das zin,
quod c[~o]flatur ut plumbum nigrum, ex pyrite, galena, et lapillis nigris.
Deinde uides stannum Plinio esse quidda de plumbo nigro, nempe primum
fluorem plumbi nigri, als wann man vnser bley ertz schmeltzet, das erst das

pl[~u]bo candido, mit vnserm zinn, vnd wann du ihm recht nachdenckest,
daruon die kannen gemacht werden, das man halbwerck heist.... O ir losen
vngelerten, vnckenbrenner. Stannum proculdubio Arabis metallum est
preciosius nostro candido plumbo: sicuti apud nos bisemuthum quiddam plumbo
preciosius."

impossible to give in English this play on words between veins of ore and
veins of the animal body.

dicimus._--See the notes on Gilbert's glossary, _ante_. The word verticity
remained in the language. On p. 140 of Joseph Glanvill's _Vanity of
Dogmatizing_ (Lond., 1661) we read: "We believe the _verticity_ of the
_Needle_, without a Certificate from the _dayes_ of _old_."

[85] PAGE 29, LINE 15. Page 29, line 16. _Nos vero diligentius omnia
experientes._--The method of carefully trying everything, instead of
accepting statements on authority, is characteristic of Gilbert's work. The
large asterisks affixed to Chapters IX. X. XI. XII. and XIII. of Book I.
indicate that Gilbert considered them to announce important original
magnetical discoveries. The electrical discoveries of Book II., Chapter
II., are similarly distinguished. A rich crop of new magnetical
experiments, marked with marginal asterisks, large and small, is to be
found in Book II., from Chapter XV. to Chapter XXXIV.; while a
