tiful fpots ; the florid red looking like drops of blood, with its 

 ferum about it. This was found on the Ihorc of North Tyne, by 

 the iflet near Chipchace mill. It is of an irregular fliape, ponde- 

 rous, and feems to be broken off a larger mafs. It is the Hzma- 

 chates or blood-ftone of the antients (I). I have a beautiful va- 

 riety of it, with an admixture of brown, and white veins, from 

 the more of the Tyne, near Corbridge ; and another from the Co- 

 quet, above Rothbury the florid red fpots numerous and elegant. 

 We have it alfo on the fhores of the Tweed, and Bowmont, and the 

 neighbouring hills. I have feen fome fine ones found in thofe 

 parts ; cut and polifhed, in the pofTeffion of Mrs. Selby, of P aft on. 



4. A whitifli agate, with flefh-coloured veins, fpotted and va- 

 riegated with a bright gold-yellow, a light and deep purple, and 

 green. It is a beautiful fpecies of the H&machates. From the 

 fhore of North Tyne, below Cbolkrford-bridge. 



jr. An agate of various colours, a light and deep green, a deep 

 red, a purple, white, and a bright gold-yellow, caft into com- 

 partments, edged with purple and a gold-yellow, in a moft ele- 

 gant manner ; the white diffufed in the form of veins ; prefenting 

 to our view fuch a beautiful contrail of colouring, as can only 

 be equalled by the embroidery and brocade-attire of fome of the 

 vegetable and infect-tribes. It is fo exceffive hard, that it was the 

 labour of two men for two days to give it a tolerable fmooth fur- 

 face on a grind-ilone, and to give it a politure afterwards with 

 fmiris on a lead-mold, it took me up near a week. It is a fpecies 

 of the haemachates. It was found in the bottom of the brook bv the 



ti 



bridge at Simonburn, near a bank abounding with iron-ftone. 



6. An agate of a ftrong deep red, with large fpots of a bright
