624 APPENDIX. 



globules, very sound, and perfect in their gangart, a singular 

 accident is seen to have taken place, the discovery of which 

 is owing to mere chance. Having caused this specimen to be 

 cut, in order to be enabled to place it in my drawers, it was 

 divided into two equal parts, and the operation exposed a 

 globule two inches and three lines in diameter, a piece of 

 which had at some former time been separated from it by a 

 motion of the rock, but was again knitted to the stock in 

 such a perfect manner that the joint was scarcely perceptible. 

 This section of the globule forms a kind of crescent one inch 

 seven lines in length, which is out of its place as if repulsed 

 from the circle, but in such manner that one might fancy 

 it would assume its ancient disposition ; notwithstanding 

 which, I must repeat, it is difficult to distinguish the points 

 of connexion. 



This specimen, before it was cut, was presented to me by 

 ^ M. Rampasse. 



No. 5. An elongated oval globule, of great regularity in 

 its colours 3 in breadth one inch nine lines, in length four 

 inches two lines : it is to be presumed this elongated form is 

 owing to the union of several globules at the period of their 

 crystallisation, which thus became confounded in one oval ; 

 a line of red felspar fills the whole length of the greater 

 diameter, and the crystals diverge from this point, which 

 serves as their common centre: this specimen, highly re- 

 markable on account of its shape, has a kind of regularity in 

 all its parts. 



To conclude, the large blocks of a stone so singular and so 

 hard as this, were they worked for the purpose of introducing 

 them to the arts, whether in making of columns, tables, or 

 socles, would present pieces equally remarkable for the na- 

 ture of the stone itself, as for variety, size, the colour, 

 and form of the globules, which render it so much an object 

 of curiosity.
