MIDSHIP-FRAME

In the 8th page, from the beginning of the article Naval ARCHITECTURE, the reader will find a full explanation of what is meant by a frame of timbers. He will also perceive the out-lines of all the principal frames, with their gradual dimensions, from the midship-frame delineated in the plane of projection annexed to that article. As the parts, of which the several frames are composed, have the same relation to each other throughout the vessel; and as all the corresponding pieces, without and within those frames, are also nearly alike, and fixed in the same manner, it will be sufficient for our purpose to represent the principal, or midship-frame, together with its corresponding parts, which are as follow:

Explanation of the MIDSHIP-FRAME, plate VII. which exhibits a transverse section of a 74 gun ship, at the broadest part, answering to the same scale by which are delineated the head, quarter, and stern of a ship, of the same size, in plates IV. VIII. and X. to which the reader is referred.
