 this, his active mind never lost its interest in the studies 

 and discoveries of his earlier years. By his numerous 

 friends his society was to the last highly appreciated, and 

 his modest and kindly disposition greatly enhanced the 

 pleasure and advantage of his conversation. His single-

 genius by which it was directed to results of no ordinary 

 importance to the mechanician and the lover of natural 

 science. He died at his residence, Greenhill Street, Green- 

 heys, on November 24th, 1887.
