[Some] necessary observations on an act of the last sessions of Parliament, intituled, An act for the relief of insolvent debtors : Shewing, that (if duly executed, and adverted to by the creditors themselves, either before or after the execution thereof) the said act is calculated and enacted, by the Parliament, with equal regard to the interest of the creditors, as to the relief of those prisoners for debt, who are deemed real objects of compassion. Humbly offer'd to the consideration of the worshipful [bench] of His Majesty's Justices of the Peace, for the County of Middlesex. With a short appendix, touching a very extraordinary case, now depending before their worships; in a letter to one of their number. By Roderick Mackenzie, Sen. quondam A.A.
