by the concretion or coagulation of Water,or fome other fluid body. |. 
There areother kinds of courfer Sands, which are browner, and have 
their particlesmuch bigger; thefe, view'd with a Adicro/cope, feem much 
sari and more opacous fubftances,and moft of them are of fome irregu- 
larly rounded Figures; and though they feem not f0 opacows as to the 
naked eye, yet they feem very foul and cloudy, but neither dothefe want 
eurioufly tranfparent,: no more than they do regularly figur'd and well 
colour'd particles, asI have often found. | : | | 
_ There are multitudes of other kinds of Sands, which in many particu- 
lars,plainly enough difcoverable by the Aécrofcope, differ both from thefe 
laft mention'd kinds of Sands, and from one another: there feeming to be 
as great variety of Sands,as there is of Stones. And'as among{t Stones fome 
are call'd precious fromtheir excellency, fo alfo are there Sands which 
deferve the fame Epithite for their beauty ; for viewing a {mall parcel of 
Eaft-India Sand (which was given me by my highly honoured friend, Mr. 
Daniel Colwal) and, fince that, another parcel, much of the fame kind, 
I found feveral of them, both very tranfparent like precious Stones, and 
regularly figur'd like Cryftal, Corzi/h Diamants, fome Rubies, @e. and 
alfo ting'd with very lively and deep colours, like Rabys, Saphyrs, Eme- 
ralds,&c. Thefe kinds of granulsI have often found alfo in Exgli/h Sand.

It were endlefs to defcribe the multitudes of Figures Ihave met with 
in thefe kind of minute bodies, fuch.as Spherical,Qval,Pyramidal, Conical, 
Prifmeatical, of each of which kinds I have taken notice, eli suet 
_ Butamongft many others, I met with none more obfervable than this 
pretty Shell (defcribed.in the Figure X. of the. fifth scheme). which; 
though as it was light on, by chance, deferv’d to have been omitted (I 
being unable to direét any one to find the like) yet for its rarity was it not 
inconfiderable, efpecially upon the account of the information it may 
afford us. For by it we have a very good inftance of the curiofity of Na- 
ture in another kind of Animals which are remov'd, by reafon of their 
minutenefs,beyond the reach of our eyes; fo that asthere are feveral forts 
of Infects, as Mites, and.others,fo final! as not yet. to have had'any names 5
