REVEREND SiR, i 
*¢Thave fent afew linesto Mr. MATTHEWS 
in London, (a copy of which is on the other 
fide of this paper) to be inferted in your 
Miffionary Magazine. But this morning I 
accidentally difcovered, that he only fells it, 
and that communications addrefled to ‘you, 
may be left with any of the publifbers. Fear 
ing, therefore, that you may not receive eis 
communication in time, (for I muit have it 
in this month, or prefent it to the public 
through fome other channei), I now tran- 
feribe it; that it may pals dire&tly from 
Northampton to Edinburgh. 
se The account pes in the number for 
Auguft, refpeéting the diffolution of the 
Academy at Northampton, Which, indeed, I 
did not fee till lat w eek, is fuch a Morel 
fiab to my charaéter, as to require immediate 
Motice. And how you, wha know fo little 
of the internal concerns and regulatiens of 
the Academy, could admit fuch a libel, (not 
to fay write it, though I think ycu are re- 
fponfible as .the Editor,) is, tO many, very- 
aftonifhing. Where-tam known, and here 
in particular, where I have refided three and 
twenty years, I flatter myfelf that I poffefs 
a character, too well eftablifhed to be eafily 
overthrown. But if the infinuations and 
charges in that paper were true, I muft be 
not only defective in character, and fome- 
what cenfurable, but a villdin of uncommon 
magnitude.——T'o fap the foundations of chrif- 
fianity under the pretence of refining it.— 
to teach, in a clandefine manner, principles 
ceftru€tive of thofe which I had profeffed ; 
and to conceal the fiate of the feminary Eon 
the truftees, and yet know that to be as 
had as 8 writer reprefents it? What could 
be worfe! And this is the light in which 
you poft me up to the public, as widely as 
ae Magazine circulates. “Now, Sir, re- 
onfider this a moment. Is_ this treating 
shdunee as you would wifhto be treated your- 
felf? Could not the diffolution of the Nor- 
thampton Academy have been announced to 
the public without thefe falfe infinuations 
and virulent afperfions? Surely this is no 
Part of the fpirit of chriftian meeknefs, or 
Lrotherly love, which our comman Mafer 
taught, and which your Magazine, asa re- 
ligious one, undoubtedly ought to inculcate.”

AccounNr oF THE Mines oF Spain, 
By M. HOPPENSACK*. 
R. HOPPENSACK, # appre stend- 
ant of the Spanish mines » publithed 
in 1796 two memoirs on this fubjett, 
written in the German language, which 
contain fome interefting matter. It is 
well known that the Romans ufed te pro- 
cure 2 confiderable quantity of gold fron. 
Spain; and they alfo obtained iron, filver, 
and copper. Mr. H. found in an ancient 
mine a piece of impure copper, containing. 
more than a tenth part of its weight 
of filver, vitreous filver ore with heen 
filver, and ponderous ipar with red filver 
ore. Inthe times of the Goths and Sa- 
racens thefe mines were negleéted, fo that 
only fmal! quantities. of lead and copper 
were obtained from them; and they are 
is neglected; the quickfilver mines alone 
ccupying the publieattention. The fa, 
mous Counts Fugger in 1551 obtained 
the privilege of working the filver mine 
at Guadaleaval, anciently occupi ied by 
the Carthaginians. They found it very 
rich, fo that it had for fome years yielded 
to the king annually twenty-four millions 
of reals as his. fitth. They continued to 
work it for thirty years, which was the 
vs of their grant, and afterwards it 
fell into the hands of a French company. 
In 1775, Mr. H. had the fuper intendence - 
of it; but the works were in a ruinous 
ftate, "and but little ore was left. He pro- 
Bord to abandon the old works, and fink 
new ones; but this was deemed too ha- 
zardoug, and in 1779 the company was 
broken up. 
The mountains of Guadaleaval are 
compofed. of argillaceous fchift with mica. 
The veins in which the metal is found are 
commonly ponderous pee quartz, and - 
micaceeus fand. 
There is found at ‘Tock ina gangue. 
of quartz and white feldfpar, Brey copper 
ore, cupreous pyrites, grey filver ore, 
(fablers ) oxyd of copper in cryftals, ful- 
phuret of antimony, aud cinnabar; and 
on account of this laft, the Spanifh go- 
vernment take the working of it into their 
own hands.
