drawn in a given time to the number of prizes drawn, 
is continually increafing as thefe numbers increafe ; 
and that therefore, when they are confiderably large, 
this conclulion may be looked upon as morally cer- 
tain, By parity of reafon, it follows univerfally, with 
refpedt to every event about which a great number 
of experiments has been made, that the caufes of its 
happening bear the fame proportion to the caules of 
its failing, with the number of happenings to the 
number of failures ; and that, if an event whole 
caufes are fuppofed to be known, happens oftener or 
feldomer than is agreeable to this conclulion, there 
will be reafon to believe that there are fome unknown 
caufes which difturb the operations of the known 
ones. With refpeCt, therefore, particularly to the 
courfe of events in nature, it appears, that there is 
demonftrative evidence to prove that they are derived 
from permanent caufes, or laws originally eftablifhed 
in the conftitution of nature in order to produce that 
order of events which we obferve, and not from any 
of the powers of chance*. This is juft as evident 
as it would be, in the cafe I have infifted on, that the 
reafon of drawing io times more blanks than prizes 
in millions of trials, was, that there were in the wheel 
about fo many more blanks than prizes . 
But to proceed a little further in the demonftration 
of this point. 
We have feen that fuppoling a perfon, ignorant of 
the whole fcheme of a lottery, fhould be led to con- 
jecture, from hearing ioo blanks s&d io prizes drawn,
