BIBLIOGRAPHY OF THE PRODROMUS 195 



X, XI), reproducing them, however, in the original size,^ and pre- 

 serving the numerical order. The ' explanation of the figures ' in 

 the original edition is printed on an accompanying double-page fold- 

 ing inset. Page 79, not numbered, contains a list of corrections, 

 which is far from complete. 



There are two copies of the original edition in the British 

 Museum. The copy which I examined (press mark 537. b. i) has a 

 plate preceding the text and a duplicate of it following the explicatio 

 figurarum. A number of marginal corrections of the text have 

 been made by some scholarly reader, for they are essential in every 

 case. There is also a copy in the Library of the Royal Society, 

 London ; it is bound up with various tracts, and contains marginal 

 corrections, but by a less careful hand. In this copy the plate and 

 ' explanation of figures ' are inserted in the front of the treatise. 



The only copy which I have found in the United States is in the 

 New York Public Library, and carries the stamp of the Astor 

 Library on its title-page. It is in perfect condition and without 

 marginal corrections.
