'Hooke was a man of extraordinary inventive genius, and has justly been considered as the greatest of philosophical 

 mechanics. There was no important invention by any philosopher of that time which was not in part anticipated by 

 Hooke. His theory of gravitation subsequently formed part of Newton's ; he anticipated the invention of the steam engine, 

 and the discovery of the laws of the constrained motions of planets. Among his own completed discoveries are the law of 

 the extension and compression of ela.stic bodies, the balance spring of watches and the anchor-e.scapement clocks, and the 

 permanency of the temperature of boiling water. The quadrant, telescope, and micro.scope are also materially indebted 

 to him.' The above three works comprise all ever printed of his writings.
