viii THE ECHINODERMS OF TORRES STRAIT. 
are contrary to his expressed wishes and are offered merely for the satisfaction of 
my own feelings. To Mr. E. M. Grosse, of Sydney, who went with us to Torres 
Strait as artist, my heartiest thanks are due, not only for the beautiful figures 
which adorn the first nineteen plates of this memoir, but also for his careful super- 
vision of the lithographing of those plates at the New South Wales Government 
Printing Office in Sydney. Mr. Grosse’s skill is amply attested by the plates them- 
selves, but only those who were in our party can fully appreciate the patience, 
persistence, and enthusiasm with which his work was done. To Lieut. Frank A. 
Potts, M. A., of Cambridge, England, Dr. E. Newton Harvey, of Princeton, and 
Professor David H. Tennent, of Bryn Mawr, the other members of the party, I 
am glad to express my thanks, not only for their constant kindness and codperation, 
but for many valuable specimens. Mr. John W. Mills, our engineer, was always 
eager to help in every possible way, and many a fine specimen I owe to his enthusi- 
astic interest. Mr. John S. Bruce, government teacher and magistrate on Mer, 
was constantly helpful and placed me under great obligation to him. Mr. Thomas 
A. Williams, who, at the time of our visit was magistrate on Erub, was also most 
hospitable. I am under very real obligations to Mr. George Clark, of Thursday 
Island, for his kindly help. The late Mr. R. Etheridge, curator of the Australian 
Museum, was untiring in his efforts to have me properly equipped for collecting 
in Torres Strait; it gives me great pleasure to acknowledge here his many kind- 
nesses and his unfailing interest. The assistant curator, Mr. Charles Hedley, was 
also most helpful, and to him I feel under special obligation, for it was largely due 
to his advice that we went to Mer. Finally, I wish to thank Mr. Samuel Henshaw, 
Director of the Museum of Comparative Zodélogy, for the extended leave of absence 
which made the trip possible, and also for helpful suggestions in connection with 
the preparation of the plates for this report.
