The report is not so complete as wished for, but the immediate 
departure of Dr. Breinl and myself on an expedition to Brazil has compelled 
us to give our results in the manner here presented. We hope to fill in the 
omissions at an early date. 
In conclusion I wish to acknowledge, on behalf of the research workers, 
the courtesy and interest which so many have evinced in the work. In 
particular Professors Boyce, Ross, Sherrington, and Moore, Dr. J. W. W. 
Stephens, Dr. J. Hill Abram, Dr. Lloyd Roberts, Professor Grunbaum, 
and Dr. Ernest Glynn, Dr. Lauder, Medical Health and Port Sanitary 
Officer, Southampton, his assistant, Dr. McCulloch, and the Matron of 
the Southampton Isolation Hospital. 
I cannot close without expressing my indebtedness to Dr. H. E. Annett, 
who has done everything possible to aid the research department, to him 
and Professor Boyce the numerous worries and difficulties associated with 
the work have been left. 
To the gentlemen on the committee and the Hon. Secretary of the 
School, who have endeavoured to meet all the requirements of the division, 
our thanks are tendered. 
On behalf of the workers 
H. W. THOMAS
