Sir R. T. Guazesproox, Mr. W. Hati, Dr. Haroip Jerrreys, Prof. 
H. Lamps, Sir J. Larmor, Prof. A. E. H. Love, Prof. H. M. Mac- 
DONALD, Prof. E. A. Minne, Dr. A. Cricuton Mircuett, Mr. R. D.

Row tanp, 8.J., Prof. R. A. Sampson, Sir A. Scuuster, Sir Napier 
Suaw, Capt. H. Suaw, Sir F. E. Surrs, Mr. R. Sronetey, Sir G. T. 
WALKER and Dr. F. J. W. Wuipp.e). 
Smvcz the last report was drawn up our esteemed chairman, Prof. H. H. Turner, has 
passed away. He died at Stockholm on August 20, 1930, where he had gone in his 
capacity as president of the Seismological Section of the International Union of 
Geodesy and Geophysics, and also as chairman of this committee. He was elected 
to the latter office on February 21, 1907, and during the twenty-three years that he 
has occupied the position it would have been difficult to find one who had more 
assiduously promoted the interests of seismology, It would be inappropriate to 
attempt to give here a record of his many activities in the interest of the science. His 
- work in developing and increasing the usefulness of the summary, and his researches 
on Deep Foci are well known ; but perhaps not the least service he rendered was the 
collaboration he secured by the encouragement he gave, not merely to those at home, 
but also to observers in all parts of the world. During the year Mr. F. A. Bellamy 
and Miss E. F. Bellamy have compiled and issued, as a labour of love, a most valuable 
brochure, detailing the extensive nature of Prof. Turner’s seismological work. A 
paragraph in theireview may be quoted here as the hope of this committee—that 
‘the amount of work, energy and interest that Turner threw heartily into Seismology, 
its continuance as a tribute of respect to John Milne, and his great desire that that 
part of the seismological work—the digest of the world’s earthquake records—should 
be maintained at Oxford and be associated with the University Observatory, are 
points worthy of consideration for placing this part of seismological work upon a 
permanent basis in this country as a lasting memorial to both John Milne and Herbert 
Hall Turner.’ He was a man whom it will be difficult to replace. In the interregnum 
Sir Henry Lyons has kindly consented to accept the chairmanship. Up to the present 
time circumstances have delayed the appointment of a successor to Prof. Turner at 
Oxford, but the University expressed a wish that the seismological work should 
continue without any alteration ; therefore, until the University fills the vacancy it 
would be inadvisable for this committee to make any plans for the future. 
INSTRUMENTAL. 
The two Milne-Shaw seismographs at Oxford have continued to function satis- 
factorily, but the instability of the masonry pier, which has been referred to in previous 
reports, still continues. 
It may be well to place on record particulars of the five instruments which belong 
to the Seismological Committee.
