INDEX OF NAMES. 



Roman figures refer to the chapters, Arabic to the articles. The 

 numbers given in brackets after the name of an astronomer are 

 the dates of birth and death. All dates are A.D. unless otherwise 

 stated. In cases in which an author s name occurs in several 

 articles, the numbers of the articles in which the principal account of 

 him or of his work is given are printed in clarendon type thus : 286. 

 The names of living astronomers are italicised.
