brccatello, or brocettelato. The figures are chiefly 

 regarded in the Paefmo di Fiorenza, Alberino di 

 Monte Gallicano^ &c. &c. When fome of the 

 originals are wanted to compleat the whole fet of 

 marbles, they are fubftituted either by others, 

 that have the moll refemblance to them, or by 

 white marbles itained or coloured; and this is 

 the cafe with the Marmore di fatigue di Dragone. 



To this fpecies of folid limeilone alfo belongs 

 the marble from Blankenburg, which is red, 

 black, and white-, likewife that from the pro- 

 vince of Jemtland in Sweden, which is black 

 and white, or only black, and the French mar- 

 bles, viz. Serfontaine, Antin, Seracolin, St. Baume, 

 Servelat, &c. &c. which have feveral bright co- 

 lours. 



The fineft folid modern marbles are thofe from 

 Italy, Blankenburg, France, and Flanders. There 

 are alfo marbles dug in Saxony, and other parts 

 of Germany, in Norway, and Sweden; but ei- 

 ther they are not of fuch agreeabjp or ftriking 

 colours, or elfe are of that fpecies which is call- 

 ed the Scaly glittering Limeilone, mentioned 

 Sect. ix. 



There are, however, feveral among the above- 

 mentioned marbles, which are partly mixed with 

 the fcaly limeilone (Seel. ix. ), though not in 

 fuch a quantity as to conftitute the principal part 

 of the ftone, but only as a fubilance which has 

 joined together lumps of the folid limeilone, or 

 elfe filled up its empty crevices or cracks.. This 

 kind, however, ought not to be rejected, but 

 might be ufed as a marble, if only fuch pieces 

 were^hofen that have the fineft texture: becaufe 

 thofe with coarfe fealejs, when polifhed, are of an 

 icy appearance, as mafons term it, and do not 

 fnew their true colours, by reafon of the femi-
