works of the early members of the Merton 

 School of astronomer-physicians have been 

 brought together. They belong to a group 

 of men of the fourteenth century — Reed, 

 Aschenden, SimonBredon, Merle, Richard 

 of Wallingford, and others — whose la- 

 bours made Oxford the leading scientific 

 university of the world. 



Little remains of the scientific apparatus 

 of the early period of the Royal Society, but 

 through the kindness of the Dean and Gov- 

 erning Body of Christ Church, the entire 

 contents of tlie cabinet of philosophical 

 apparatus of the Earl of Orrery, who flour- 

 ished some thirty years after the founda- 

 tion of the Society, is on exhibit, and the 

 actual astronomical model, the ' ' Orrery, ' ' 

 made for him and called after his name. 1 



1 Among other notable exhibits there are : 



I . A series of astronomical volvelles in manuscripts and printed 

 books. 



a. The printed evidence that Leonard Digges of University Col- 

 lege was the inventor of the telescope many years before Galileo. 



3. The mathematical work of Robert Recorde of All Souls*
