The Atlantic Neptune, published for the use of the Royal Navy of Great Britain,

L.C. copy no. 20, with 25 items.
Consists of the New England section only, in contemporary binding, probably issued in 1780. The general t.p. to v. 1 accompanying it, however, belongs with the Nova Scotia series of charts. In various dated "editions" the New England charts appear with general title pages called v. 2, 3, or 4, but not v. 1.
The printed sectional t.p. is undated, and includes the reference to Lord Howe.
The printed contents leaf which follows has ms. additions. Of the 23 items listed, no. 9, 12, and 23 are added in ms. No. 16 is omitted.
The charts, dated 1775 to 1776, are all 1st or 2d states of the plates, on heavy paper with the "LVG-IV" watermark.
L.C. copy imperfect: chart no. 11 of the contents leaf, "The Coast from Newbury to Cape Elizabeth," wanting; 3 other charts are incomplete, especially no. 23, "Grand Bay of Passamaquody," which lacks the "Grand Manan Island" section.
In ms. on fly leaf preceding the general t.p.: War Office of the United States. May 7th 1790.
