of thofe Rules or Theorems fhould be objected again!!:, meer- 
Jy becaufe they tend to introduce fome Alterations in the 
prefent pra&ice; I {hall for anfwer only add, with fubmiffion, 
to what is before faid, that in former Ages, when our Laws 
relating to thefe matters had their rife, (the Profits of England 
arifing chiefly from Husbandry and Tillage, and little from 
Trade,} the Calh of the Kingdom was but low, the Rates 
of Intereft very high to the Advantage of Ufurers, and thofe 
ways for the ready Improvement of Money accomodated to all 
Peoples ufe, not known ; (much like to which we are told was 
the State of the Jewifh Affairs, when they were forbidden to 
take Ufury of any but Strangers.) But latter Ageshavepro- 
duc’d vaft Alterations in all thefe Refpe&s, which having 
happen’d by infenfible degrees, may be one reafon why nei- 
ther our Legiflature, nor Courts of Judicature have yet taken 
fuch notice thereof, as time and Icifure, with the Tender 
of proper and practical Methods of Computation, may here* 
after induce them to do.
