PREFACE, 
—_-——_ 
UST as he was completing the work of editing this Volume 
Mr. H. Charlewood Turner was obliged through ill-health 
to resign his duties as Secretary of the Institute and Editor 
of the Journal. He retires with the best wishes of the Council 
for his speedy recovery and their sincere thanks for the good 
work he has done during his two years of oftice. 
In putting the finishing touches to his work as Editor it 
devolves upon me to write this preface. I commence the work 
with the benefit which thirty years’ membership of the Institute 
and two years’ experience on the Council has given me; but I 
enter upon the duties with the greater confidence because it is 
‘the unanimous wish of my colleages that I should do so, and 
because I know I can rely upon their cordial help. 
The Council regrets that owing to the causes mentioned above 
the publication of this Volume has been delayed beyond its 
usual time of issue. They desire me to express their acknow- 
ledgments to the writers of papers and to those taking part in 
the discussions, and invite the assistance of members in 
obtaining high-class papers suited to the needs of the times 
and an increase in the number of Members and Associates. 
I have pleasure in recording the taithful and efficient help of 
the Assistant Secretary, Mr. A. E. Montague, to whom the 
Institute owes much for the unseen but none the less important 
work which he does so conscientiously and successfully. 
FREDERIC S. BISHOP, 
Secretary.
