Fig. xl ix. A cubical die of mundic, with its redangles planed 
off, as c, d, e. 
l. A rhombus, #, betwixt four Hopes ; the two uppermoft, d d, 
triangular; the two underneath, b b, incomplete triangles; their 
apices planed off. From Huel-Cock in St. Juft, 1750. 
li. Another view of the fame mundic-grain, exhibiting the odo- 
gon, c, betwixt four triangular Hopes, d, </, d> d. 
li 1. A very exad parallelopiped of a gold-colour. 
liii. A cube of mundic with this peculiarity, that it has five 
of its eight angles with their apices as it were cut off, and yet of 
the fame polifhed furface as the reft of the cube. 
liv. A piece of tubulary- wreathed, brafs- coloured, fparkling 
mundic. 
lv. Another fpecimen of the fame kind, brafs-coloured. 
lvi. A vermicular fcroll of mundic, thrown into irregular mean- 
ders as if once the habitation of an infed. TV. B. Thefe may be 
called Vertnicularia glomerata , as Lhuyd calls the ftony foftils of 
of like fhape ( Lithophylacium, N°. 1215) from the ftone quarries 
near Thame in Oxfordfhire, and may ferve to fhew that we have 
extraneous foftils of the vermicular, as well as teftaceous, and fun- 
goeid kind in mundic \ 
lvii. A heptahedral cufpis of yellow, polifhed-mundic. 
lvi 1 1. A tetrahedral cufpis of brafs-coloured mundic, with two 
oppofite Hdes quadrangular, two triangular. 
lix. Tetrahedral cufpides of mundic, the fides triangular. 
lx. Two pyramids of a quadrangular plan joined bale to bale. 
lx 1. Wire- wrought, globular, buttony mundic, from the Pool 
copper- work, 1756.

lx 1 v . Three echinated balls of buttony-mundic conneded. From 
the fame mine. 
Here we have in mundic the refemblances of plants and animals, 
the moldings, cafts, and carvings of fancy, the figures of fcience 
and erudition, and more varieties will occur doubtlefs to thofe who 
fearch longer and with greater attention than I have done ; but 
thefe are enough to furprize us with their regularity and art. The 
firft of thefe may proceed from natural principles (fuch as mineral 
or metallic falts) determined to ad in a particular manner, although 
to produce fuch a multiplicity of geometrical, fpherical, and redi- 
linear figures, as are here exhibited, thefe principles muft be very 
* The following figures are fupplemental ; the dies, as the laft four do to the convex circular 
four firft belong to the clafs of geometrical mun- mundics.
