The communication which I now have the honour to lay before the Society of Antiquaries presupposes a knowledge of the contents of my two papers concerning Jersey antiquities already published in Archaeologia. I beg to thank the Society for enabling these successive reports on the excavations of La Cotte de St. Brelade to be printed and illustrated on so generous a scale. I would here take the opportunity of likewise acknowledging my debt to many other helpers: first, to Mr. G. F. B. de Gruchy, Seigneur of Noirmont, and owner of the cave, who has not only made over the whole of the treasure-trove to public institutions, providing funds into the bargain in order as it were to exploit him-self, but has throughout been my constant adjutant and co-worker; then to my Oxford friends and pupils who have at considerable cost to themselves taken part in the work for weeks and months together, Captain A. H. Coltart and Mrs. Coltart, Mr. T. B. Kittredge, Mr. B. de Chrustchoff, Miss Bayly, Mr. R. de J. Fleming Struthers, the Rev. E. O. James, Mrs. Jenkinson, Mr. P. H. Brodie; next, to Jersey residents innumerable, most of them ardent members of the Societe Jersiaise, such as, to mention but a few, Mr. E. T. Nicolle, Mr. J. Sinel, the late Dr. A. Dunlop, Mr. H. J. Baal, Mrs. Briard, Mrs. Symons, Mr. G. Le Bas, Mr. A. H. Barreau, Mr. E. F. Guiton, the two last-mentioned gentlemen having as draughtsman and photographer respectively helped largely to make our results intelligible by way of the eye; and, finally, to the many experts who have in various ways assisted in the interpretation of what we brought to light, among them being Sir Hercules Read and Mr. Reginald A. Smith of the British Museum; Dr. A. Smith Woodward and Dr. C. Andrews of the British Museum of Natural History; Dr. A. Keith of the Royal College of Surgeons; and Professor W. J. Sollas and Mr. H. Balfour of Oxford. Let me add, in order to save the face of my kind allies and advisers, that I am in the last resort responsible for every statement of fact or opinion that appears here.
