INTRODUCTORY NOTE. 



The members of the Staff upon whom now devolves the task of preparing material for the 

 press and of proof-reading, etc., are Miss Vagner and Miss Barnard. Miss Chapman carried on 

 her work until December 1920, with frequent absences owing to ill-health. She has now 

 definitely for the same reason been obliged to resign her post, much to the regret of the 

 Committee. 



The Committee desires once more to record its indebtedness to the Staff for the zeal and 

 ability they have continued to show in carrying out their duties, and to the Syndics of the 

 Cambridge University Press for their unceasing care and efficiency in carrying out their part of 

 this great undertaking. Difficulties in the printing and publishing trade, which for a time 

 delayed the delivery of proofs l'egularly, have now been overcome, and the Committee looks 

 forward with confidence to an early completion of the remaining volumes. 



July, 1921.
