INTRODUCTION OF THE MICROSCOPE 



^r> 



scopic observation did not produce its great results until the 

 nineteenth century, just after magnifying-lenses had been 

 greatly improved. 



Robert Hooke (1635-1703), of London, published in 1665 

 a book of observations with the microsco})e entitled Micro- 

 graphia, which was embellished with eight}'-three plates of 

 figures. Hooke was a man of fme mental endowment, ^\■ho 

 had received a good scientific 

 training at the University of 

 Cambridge, but who lacked 

 fixedness of purpose in the 

 employment of his talents. 

 He did grood work in math- 

 ematics, made many models 

 for experimenting with flying 

 machines, and claimed to have 

 discovered gravitation
