Candles, Sopes, Starch, &c. which have been Duties subsisting by Law almost 30 Years; and are very considerable Branches of the Revenue as well as of every Excise Officer's Duty, tho' yet they have never been so much as once touch'd upon by any Author. With the Officer's Duty in the Distillery. Part II.
