In offering some observations on the prehistory of Malta, the fruit of a month's visit to the island in the Easter Vacation of 1927, Dr. Marett disclaimed all intention of contributing positively to the subject, and hoped at most to draw attention to sundry matters standing in need of further investigation. All British archæologists should pay Malta a visit, if only in order to enjoy the experience of visiting its wonderful monuments under the guidance of local experts such as Professor T. Zammit and Dr. G. Despott, who are as kind as they are learned and patriotically keen. Dr. Marett was also anxious to acknowledge his great debt to the Royal Air Force for allowing him to explore Malta and Gozo from the air—a most instructive method not only of taking in the ground-plan of a given site but likewise of viewing the various sites in their geographical relation to each other; while several magnificent series of photographs taken by the R.A.F. in the course of their aerial surveys were most generously placed at his disposal and proved to be archæologically, not less than otherwise, of the greatest interest and value.
