READERS. A Series of Monthly Volumes. Price 2s. 6d@. bound in cloth. 
Edited by Rev. W. LUCAS COLLINS, Author of ‘Etoniana,” the 
“Public Schools,” &c. 
The aim of the present series will be to explain, sufficiently for general 
readers, who these great writers were, and what they wrote ; to give, where- 
ever possible, some connected outline of the story which they tell, or the facts 
which they record, checked by the results of modern investigations; to 
present some of their most striking passages in approved English translations, 
and to illustrate them generally from modern writers; to serve, in short, as a 
popular retrospect of the chief literature of Greece and Rome. 
Volume I., containing HOMER: THE ILIAD), is this day published. 
A Prospectus may be had on application to the Publishers.
