An interesting account of two ' navigable ' balloons, one of an oval form and the other resembling that of a ship, which 



in both cases are directed by parachutes, serving fora rudder in one case, and in the other for a sail. 



The work was unknown to Hatton Turner, and must be very rare, as well as one more instance of the craving of the 

 French aristocracy for the dernier cri de la vie sportive.
