WITH NOTES. 509 



is no doubt to be so contrived that the opening and 

 closing of such case, to ascertain the time, shall act 

 more or less to wind it up. A room door has been thus 

 made to transmit power through attached levers to keep 

 a clock constantly wound little by little, every time on 

 opening and closing the door. 



His list of certain of his inventions gives a different 

 reading to this article ; as follows : &quot; I can render an 

 ordinary watch, which, being once wound up, will go 

 constantly during a man s life, being used but once in 

 24 hours ; and, though oftener looked on, it is still the 

 same ; and though not looked on for a week, still the 

 same, if not bruised.&quot; See Appendix A. 



And in his patent of 1660, we have again a third 

 reading, viz : u To make a watch or clock without 

 string or chain, or any other kind of winding up but 

 what of necessity must follow, if the owner or keeper 

 of the said watch or clock will know the hour of day 

 or night ; and yet if he lay it aside several days or 

 weeks without looking or meddling with it, it shall go 

 very well, and as justly as most watches that ever were 

 made.&quot; See Appendix B. 



In &quot;Humane Industry,&quot; chapter I, occur the following 

 remarks, &quot;On Dials,&quot; page 8 : &quot; The wit of man hath 

 been luxuriant and wanton in the inventions of late 

 years ; some have made watches so small and light, that 

 ladies hang them at their ears like pendants and jewels ; 

 the smallness and variety of tools that are used about 

 these small engines, seem to me no less admirable 

 then the engines themselves; and there is more art 

 and dexterity in placing so many wheels and axles in 

 so small a compass (for some French watches do not 

 exceed the compass of a farthing) than in making clocks 

 and great machines.&quot; It is also stated at page 9, that 

 &quot; In some towns of Germany and Italy, there are
