* Note by Recorder. — To meet a widely-felt want, it was resolved to add to the 
special bibliographies a record of a more general character, which would take account 
(a) of Text-books and synthetic memoirs, (b) of contributions to the theory of organic 
evolution, and (c) of concrete studies on such general subjects as protoplasm, the 
cell, oogenesis, spermatogenesis, and the like. But as this was only resolved upon six 
weeks before the date for sending the list to press, the Recorder desires indulgence 
in regard to omissions which the limitations of time and accessible literature have 
this year rendered inevitable. 
f Monographs are not included, but will be recorded under their proper heads.
