A Note ahoittfmeun-nfual Diamonds. 
THere came to our hands, Tome while fince, a Reprefenta- 
tiOROf a Gonfiderable number of excellent Diamonds , 
fold by one Monfieur Tavemur to his King, after his laft return 
from the JE/^/^-ZW/Vx, whither he had made fix Voyages by Land. 
Amongft thefe Diamonds there are defcribed three of a very 
unufual colour ; one, weighing r r 2~ C^r^^j , of a very fine 
Violet-colour, and two of a Rofe-pale colour 3 all three of an 
Adamantin hardnefs , and upon that account efteemed Dia- 
,A certain Fh^nmemn^feen by Monjteur Hevelius, F^p^. 5. 1 674. 
St. No. not far from Marienburgh in Boruffia, about the Su»^ 
a little before his fetting and the Moons con]tinBion , and the 
Suns Ecliffe^ Qwhichyet vp44 not [eenby him.)

Horizon,and fliining very bright,yet lancing out very long and

what dikte fmall Cloud,beneath which there appeared a Mock- 
Sun, of the fame bignefs (to fenfe) with the true Sun,andunder 
the fame Vertical, of a fomewhat red colour. Soon after, the 
true Sun more and more defcending to the Horizon , towards 
the faid Cloud (as may be feen F/^. 4.) the fpurious Sun be*

in that apparent Solar disk vanilh'd , and put on the genuine 
Solar light, and that the more, the lefs the genuine disk of the 
Sunwasdiftant from the falfeSun: Till at length the upper 
true Sun pafled into the lower counterfei tone, and fo remained 
alone ; as appears Fig, 5 . 
Which Appearance being unufual, and having never been feen 
by me^ I took the freedom of imparting it unto you^efpecially 
fince here the Mock*Sun was not found at the fide of the true 
Sun, as 'tis wont to be in all Parhelia 5 feen by me , but per-
