One of the most important books ever published with regard to the history of aviation, this is the American physician John Jeffries' (February 5, 1744 - September 16, 1819) personal copy of his narratives of two balloon voyages personally undertaken in the company of the French balloonist Jean Pierre Blanchard (July 4, 1753 – March 7, 1809). The first narrative relates to the November 30, 1784 voyage wherein Jeffries and Blanchard took their first flight together from the Rhedarium behind Green Street, Mayfair, London, to Ingress in Kent. The second, more historic, voyage took place on January 7, 1785 wherein the aeronautical duo lifted off from Dover, near the Royal Castle, and crossed the English Channel to arrive two hours later at Guines, in the French province of Artois. The voyages collectively chronicled here, consist of a number of important firsts, including

1. The first international flight
2. The first air crossing of the English Channel
3. The first attempts to collect scientific data from a lighter-than-air vehicle
4. The first English-language treatise on aeronautics by an American

Jeffries was a wealthy American physician and, having caught the ballooning fever, financed the expedition himself - in the process turning Blanchard into the first professional aeronaut. Blanchard's first successful balloon flights had occurred only one year before, but in these infant stages of ballooning history, he was considered highly experienced. After the first trial flight, Blanchard agreed to take Jeffries across the channel. Blanchard must have been doubtful that the balloon could handle two people, for they carried only 30lbs lf ballast and he would only take flight on the venture after accepting an oath from Jeffries that he would jump out if necessary. Blanchard proved correct and the balloon never attained a safe altitude, but by jettisoning everything possible, from the steering gear to their coats and trousers, two two made it across the channel, landing, as it were, in little more than their smallclothes. The French erected a monument at their landing point - which is pictured in an engraving at the back of this volume, opposite the final text page.

The venture was a resounding success and marked a pivotal moment in this history of aviation. Jeffries, being a man of both means and leisure, composed a sixty page narrative describing the accomplishments in detail. The narrative consisted of a stipple-engraved portrait frontispiece by Caroline Watson after F. Russel, and an engraved plate illustrating a column to commemorate the event. Jeffries printed the volume at his own expense. It must have enjoyed a very limited print run with no commercial element, as almost all known copies are directly related to either individuals related to the voyage, their families, or dignitaries. For example, known copies bear plates from the library of Camille Blanchard (descendent of Blanchard), Benjamin Joy Jeffries (Jeffries' Grandson), George Washington, Phillip Carrigain (another doctor and friend of Jeffries), etc.

The present example bears the unique distinction of being Jeffries own copy, featuring a bookplate bearing his armorial crest and name.

The volume is a small folio in a modern period-style binding, leather spine, and marbled boards. This work exists in only one edition. Very rare.
