GLAISHER, James (1809-1903). Autograph letter signed, three pages, 8o, Blackheath, 7 January 1865, to John Percival. (Mounting traces on last leaf). The British balllonist forwards ideas for improvements in ballooning in response to a letter from Percival suggesting the use of "spiral springs attached to the Car of a Ballon to break the blow on approaching the earth." "It happens unfortunately this blow is oblique, & not always at the same inclination, so that attaching springs at the bottom of the car, or any kind of buffer, if projecting at all would be broken off." He further discusses the use of compound ballons and Mr. [Henry] Coxwell, "a practical man with balloons." | Christie's
