The following assumed typographical errors have been corrected:
Page 125: J. B. [Johann Bartholomacus] Tromsdorff--should be Johann Bartholomäus Trommsdorff?
Page 134: "paper of April 2, 1821,[22] is quite"--had "1921."
Footnote 13: "_Geschichte der Elektrizität_"--had "Elektrizitat."
Footnote 16: "_Journal für Chemie und Physik_"--had "and."
One questionable spelling has been retained as follows:
Footnote 20: "Sur le Multiplier electro-magnetique..."--should be "Multiplicateur"?

_Robert Fulton's "Steam Battery," a catamaran-type blockship, was built during the War of 1812. Until recently, not enough material has been available to permit a reasonably accurate reconstruction of what is generally acknowledged to be the first steam man-of-war._
_With the discovery, in the Danish Royal Archives at Copenhagen, of plans of this vessel, it is now possible to prepare a reconstruction and to build a model._
_This article summarizes the history of the vessel, describes the plans and the reconstruction, and also evaluates its design with particular attention to the double-hull construction._
THE AUTHOR: _Howard I. Chapelle is curator of transportation in the Smithsonian Institution's Museum of History and Technology._
The identity of the first steam man-of-war has been known for many years, and a great deal has been written and published on the history of this American vessel. Until recently, the only available drawing of the ship has been a patent drawing made for Robert Fulton. This does not comply with contemporary descriptions of the steamer and the drawing or plan is out of proportion with the known dimensions. The lack of plans has heretofore made it impossible to illustrate the vessel with any degree of precision, or to build a scale model.
