"THE BALLOON

"Two very decided failures, of late - those of Mr Henson and Sir George Cayley - had much weakened the public interest
subject of aerial navigation
Mr Henson's scheme (which at first was considered very feasible even by men of science,) was founded
principle of an inclined plane, started from an eminence by an extrinsic force, applied and continued
revolution of impinging vanes, in form and number resembling the vanes of

But, in all the experiments made with models

only of adapting

word, to

as regards the mode

The propelling principle, or power, was here, also, applied to interrupted surfaces, or vanes, put in revolution
These vanes were four in number, but were found entirely ineffectual in moving the balloon, or in aiding its ascending power
The whole project was thus

"Like Sir George Cayley's balloon, his own was an ellipsoid
Its length was thirteen feet six inches - height, six feet eight inches
It contained about three hundred and twenty cubic feet of gas, which, if pure hydrogen, would support twenty-one pounds upon its first inflation,

The rudder was

widest, one foot
Its weight was about two ounces
It
turned _flat_, and directed upwards or downwards,

he might desire to act; thus determining the balloon

, it excited very little interest in comparison

"The balloon is composed of silk, varnished

of vast dimensions, containing more than 40,000 cubic feet of gas; but as coal gas was employed in place

The coal gas is
much less costly, but is easily procured and managed

"For its introduction into common use for purposes of aerostation,

Up

exceedingly expensive, but uncertain
