rect opposition to that of Newton and Laplace, as well as of 

 every other writer of any authority with whom I am ac- 

 quainted. In fact, it is almost universally admitted that the 

 velocity increases proportionally to the square root of the ba- 

 rometric pressure. 1 have formerly shown that the velocity 

 increases, in a mean state of the atmosphere, at the rate of 

 about 1 9 feet per second, for an increase of one inch in the 

 height of the barometer; and about one foot for an increase 

 of one degree of temperature by Fahrenheit's thermometer. 

 Indeed, by applying the formula which I gave in a paper on 

 Mr. Goldingham's observations, to those of Messrs. Parry and 

 Foster, as far as they have supplied the necessary data, theory 

 and observation will agree to within about 20 feet per second, 

 — a pretty strong proof that theory is not contradicted by their 

 experiments. There is reason to believe, had the other ne- 

 cessary data been stated, that a still nearer agreement would 

 have been obtained. These it is greatly to be desired will be 

 carefully attended to by future observers.
