362 Kershaw . — Structure of the Ovule of Myrica Gale. 
I take this opportunity of thanking Professor Weiss for the help he has 
given me in this work, and the many suggestions he has made from time to 
time ; also my thanks are due to Miss K. H. Coward, M.Sc., for preparing 
many of the necessary microtome sections.
