It was seen and heard to fall into a drain ; splashed about 

 the water and mud ; penetrated 1 3 inches, and made a hole 

 14 inchet in diameter; forcing its way into a sand stone 

 rock ; no warmth could however be perceived in it. 



From the Journals of the Royal Institution. If. :6. 



It had long been conjectured by several persons in this 

 country, that the stones said to have fallen from the air, 

 on different parts of the earth, and lately analysed by Mr. 

 Howard, might originally have been emitted b) lunar vol- 

 canos facing the earth ; and meeting with little or no resist- 

 ance from the moon's atmosphere, might have risen to 

 such a height, as to be more powerfully attracted by the 

 earth than by the moon, and of consequence, to be 

 compelled to continue their course, until they arrived at the 

 confines of our atmosphere, and were again retarded by its 

 resistance. 



The idea has been lately renewed in France by Laplace ; 

 and the inflammation and combustion of the stones has 

 been attributed to the intense heat, which must necessarily 

 be extricated, by so great a compression of the air, as would 

 be produced by the velocity with which these bodies must 

 enter the atmosphere. 



Mr. Biot has calculated, that an initial velocity, about 

 five times as great as that which a cannon ball sometimes 

 receives, would be suflBcient for the projection of a body 

 from a lunar volcano into the limits of the earth's superior 

 attraction, which are situated at nearly one ninth of the dis- 

 tance of the earth from the moon. 



A body, entering the atmosphere with such a velocity, 

 would soon experience a resistance many thousand times 

 greater than its weight,and the velocity would therefore soon 

 be very considerably lessened. It has already been shown 

 (Journals I. 152), that a stone of moderate dimensions 

 could scarcely retain a velocity of above 200 feet in a second. 

 With respect, however, to the actual probability of tht 

 stones in question having been projected from the volcanos 

 of the moon, there will, perhaps, long be a diversity of 

 opinions.
