There are, farther, a multitude of other harmo- 

 nic Laws, as yet undifcovered ; fuch are the pro- 

 portions of magnitudes, and of the durations of 

 exiftence, in beings vegetative and fenfible, which

 age of his meadow, neither the fidelity of the 

 one, nor the temperance of the other, was able to
