' *Twas before intimated, that the Tejfera were but of 
i two Colours, White, and of a dark Brown; they were 
harder than a glaz'd and well burnt Tobacco*Pipe, and 
of a Grit fomewhat finer ; the Brown feem’d to be of 
^ the fame Subftance wich the White, but colour’d by Art, 
{as Pliny informs us the workers in Clay of old bad 
a Method to do) : they Teem’d to have been form’d in a 
Mould, and afterwards Burnt. Hence I am inclin’d to 
take the meaning of Vitruvius), where he makes fo plain 
V a diftin<llion between the Tefferte and i\\Q&Silia; that, 
the one was according to the import of the name, 
form’d by Inflruments out of Stone, Brick, and Tyle; 
the other lliaped in a Mould and Burnt. They were not 
of an equal Size, none exceeding an Inch in length; the 
fliorteft; were of an Inch: moll of them were equally 
made their whole length ; but of fomc the lower ends ter- 
minated almofl: as fliarpas a Wedge, on purpofe, as may 
be fuppos’d, to be driven where any Interftices were left : 
At their Heads likewife they were not all equal and 
alike. Tome exa6Hy Square, Tome oblong Square, Tome 
Semidunar, but none I'riangular; the Diameter of thofe 
that were Square was about ~ of an Inch 5 the longed 
Side of thofe that were oblong at the Head little exceed- 
ed half an Inch. It may be obferv’d, that the prepa- 
rations for fixing this Pavement here, go beyond thofe 
W'hich Vitruvius preferibes (in the firm Wall near fix 
Foot below the Surface, in the Bed of Clay within it 
two Foot thick, and in tire Foundation of Brick under 
the Clay). Bur when we confider the Scituation of 
the Ground here is low, not many Feet higher than the 
Sea might be elevated at Spring Tides; and that it 
might as well be annoy’d by Land-Springs after great 
Rains, as by Water owzing through the Earth from the
