8 HISTORY of the SOCIETY. 
Lit. Cl. Mr Daze read a paper on the Latin compound 
perfe& Tenfe, by Mr Hunter, Profeflor of Humanity in the 
Univerfity of St Andrew’s. 
Phyf. Cl. Sir JAMEs HALL communicated the remainder of 
his paper, v/x. Obfervations on the Formation of Granite. 
Sir James Hatz declined putting the two papers above men- 
tioned into the hands of the Committee for publication, as they 
refer to Dr Huttron’s Theory, which the author has not yet 
explained fo fully as he intends, but which he is preparing to 
give, accompanied by that variety of proofs and illuftrations, 
which the profound reflection, and extenfive obfervation of 
many years have furnifhed him with. The following abftract 
of them, therefore, is all that Sir James thinks it proper to 
communicate at prefent. 
Tue firft paper was fuggefted to him by a mineralogical 
excurfion which he made in 1788, in company with the Ho- 
nourable T. Doucias, among the mountains of Galloway, in 
order to examine into the curious facts refpeCting the junction 
of the granite and the fchiftus, which were firft obferved by 
Dr Hutton, as related in his paper mentioned above, and foon 
after communicated by him to Sir Jafizgs Hart. Sir JAMeEs 
accordingly having met with the line of feparation of thefe two 
bodies, continued to follow it till he made the entire circuit of 
a confiderable tract of granite country, which reaches from 
the banks of Loch Ken, where the junction is moft diftin@ly 
feen, to the valley of Palnure, and occupies a mountainous 
{pace of about eleven miles by feven; and in all this extent, 
he found, that wherever the junction of the granite with 
the fchiftus was vifible, veins of the former, from fifty yards, 
to the tenth of an inch in width, were to be feen running into the 
latter, and pervading it in all directions, fo as to put it beyond 
-all doubt, that the granite of thefe veins, and confequently 
of the great body itfelf, which he obferved forming with the 
2 veins
