PUBLISHED PAPERS BY JOSEPH ROSS 159 Because he resided for such a long period in Chingford he acquired an immense knowledge of Epping Forest, not only from the natural history point of view. In Chingford he became a well-known figure carrying either a vasculum or binoculars, and because of conditions underfoot, usually wearing gum-boots. Not only did he know the best places in which to search for the mycetozoa, in which he took a great delight, but he knew where the deer were to be found, where various species of birds were nesting, where various species of mosses and liverworts were to be seen and also the localities for all the flowering plants. A walk through part of the Forest in his company was a sheer delight for any student of natural history who was truly interested in the subject and he was a natural teacher pointing out the characters that mattered to ensure correct identification. The breadth of his knowledge may be judged by the wide scope of his published papers, a list of which is appended. He retired from active business life because of economic con- ditions in the early 1930s and this enabled him to devote his full time to his studies. Soon after he retired he took over the Curator- ship of the Club's Museum in Queen Elizabeth's Hunting Lodge and continued to care for this throughout the 1939 war. When he relinquished this post in 1948 he continued to provide the wild-flower exhibit for a further ten years when repeated attacks of pneumonia caused him to give up any active participation in the collection of specimens for this purpose, although he still visited the museum and assisted with advice and comments. He was probably best known in the Club for his work on the myce- tozoa of which he had a deep knowledge. As a result of his searches in the Forest the list of known species from the area was increased from just under 80 to 109. In addition he was jointly responsible for the discovery of a species new to science viz., Didymium laxifila G. Lister and J. Ross. Through his generosity in 1962 his entire collection of gall flies and mycetozoa were presented to the museum in which he had taken such a keen interest, where they will form a fitting memorial to his work in the cause of natural science, and his knowledge and love of the forest.
