A Plan of a 32 Pr. of modern Construction, together with that of a nine pounder on the Same plan; which will weigh 15 or 16 C being near 8 Cwt: Less than those now in use.

The Subscriber had nothing to guide him in this plan save the remembrance that 14 1/2 diameters of the Shot were the Length of the piece, & that the trunnions are one diameter & placed Six diameters before the Breech. Large Errors have not taken place in this, But should any Small ones have crept in they must be attributed to the imperfection of human memory, So common to us all! & an indulgent allowance is therefore craved.

NB a Little inspection will Shew that one general principle Leads to casting cannon of any proposed Caliber.
