208 LISTER : THE STUDY OF MYCETOZOA IN BRITAIN. of the party. By concentrating our attention on one subject and by allowing ample time for leisurely observation, discussion and enjoyment of the beauty of the scenery, many of us felt this expedition one of the most instructive and delightful that we have taken. In October and November, the Fungus and Cryptogamic Forays were, as usual, well attended and profitable. In the Forest we never draw a blank and each season provides its own charm. On these occasions, it is, I think, apparent that there is an increasing endeavour among the whole party to observe and to study something. In this way, we are carrying out one of the principal objects for which our Field Club was founded. We are becoming, in the words of our honorary secre- tary, Mr. Thompson, more "democratic," and our members are realising that each individual has a responsibility to make, if possible, a study of some group of natural objects and to share the results with others, while everyone is more alive to the help that may be given by sympathetic interest in the work of others. Two autumn meetings held by the Club were the occasion for interesting exhibits by Mr. J. Wilson, on Epping Forest Desmids, and by Mr. Charles Soar, F.L.S., on Water-mites. The January meeting gave us the privilege of the exhibition by Mr. J. H. Owen, of a magnificent series of lantern slides, illustrating the nesting habits of Sparrow-hawks, taken from photographs made by himself and some of the boys of Felsted School—a wonderful record of parental solicitude on the part of the birds, and of endurance and of ingenuity on the part of the photographers. The February meeting was distinguished by a valuable paper by Miss Champness on the death-rate of West Ham. A study of the death-rate of the population had been made in relation to over-crowding, to unhealthy sites, and to distance from open spaces ; the details were illustrated by instructive charts and maps. Two enjoyable visits have been arranged for us in the present year. In February, at the Natural History Museum, Cromwell Road, the attractive botanical gallery was explained to us by Dr. Rendle, the head of the plant department, and Mr. E. G. Baker showed an interesting historical series of flower-illustra- tions, including the delightful woodcuts of the sixteenth- century Herbals, and Ferdinand Bauer's beautiful paintings made at Kew a hundred years ago.
