years ago) has destroyed the countries then inhabited by the 

 species now living, and presefited as a habitation to the feeble 

 remains of these species, continents which had already been 

 inhabited by other beings, which an anterior revolution had 

 swallowed up, and which reappeared in their present state 

 at the time of this last revolution.

XLIX. Intelligence and Miscellaneous Articles. 



JVIr. William Shirks, formerly nautical master in the 

 royal navy, assistant to Mr. Sanderson, the mathematical 

 examiner, &c. having reflected upon the little satisfaction 

 usually gained by the common definitions of fluxions and 

 fluents, has taken upon himself to illustrate the same by 

 contemplating the augmentation of the falling body, whose 

 fluent is the square of the time, and whose fluxion is its 

 root = thc lime; whence, if the augmentation was less than 

 the square of the time, the value of the fluent would be a 

 rectangle; but if the fluent was more augmented than the 

 square of the time, the fluent would be equivalent to a solid ; 

 and if uniform, or viz. not augmented at all, the fluxion 

 and fluent would both unite and become one, in which the 

 uniformity or time only would be measured. 



Having found these definitions to answer the intended 

 purpose, Mr. Shires intends to publish a small work on this 

 subject.— He considers no other definitions requisite at 

 present.
