NOTICE TO CONTRIBUTORS. 



Contributions to the Journal should be addressed to the Editor, 

 Professor E. S. Goodrich, University Museum, Oxford. 



Contributors are requested to send typewritten manuscripts, 

 and to conclude each paper with a short sunmiary and the list of 

 works to which reference is made. The position of figures in the 

 text should be indicated, and words to be printed in spaced type 

 should be underlined. Manuscripts should be sent in fully corrected; 

 an allowance of ten shillings per sheet of sixteen pages is made for 

 alterations in the proof, contributors being responsible for any 

 excess. 



Monochrome lithographic plates will be provided where neces- 

 sary ; but further colours only in exceptional cases and after 

 consultation with the Editor. 



' Line and dot ' drawings in black process ink should be used 

 whenever possible, instead of those requiring lithography or half- 

 tone. The best results are obtained by drawing the figures on 

 a scale to be afterwards reduced. 



The size of a text-page is 6^ x 3| inches, of a single plate 

 7| X 5 inches, and of a double plate 7| x 11 inches. The placing 

 of figures across the fold is to be avoided. 



The lettering of figures should be inserted in pencil or written 

 on accurately imposed outlines on tracing-paper. 



Authors receive 50 copies of their contributions gratis, and 

 may buy additional copies, up to 100, if they apply to the Editor 

 when they return the corrected proofs.
