It may be safely said that few scientific men have sympathetically entered into bordering territories and therein excelled. The whole field of psychical research was familiar to him, and he might have been a leader in it. My last meeting with him was at his final home, the "Old Orchard," Broadstone, in 1909. I was staying at Boscombe in Hants, and he asked me to "come and see his garden, while we talked of past days." He had then the freshness of boyhood, blent with the mellow wisdom of age.--W.A.K. The eminent naturalist and traveller, Dr. Henry O. Forbes, who later explored the greater part of the lands visited by Wallace, contributes the following appreciation of the latter's scientific work: As a traveller, explorer and working naturalist, Wallace will always stand in the first rank, compared even with the most modern explorers. It ought not to be forgotten, however, how great were the difficulties, the dangers and the cost of travel fifty years ago, compared with the facilities now enjoyed by his successors, who can command steam and motor transport to wellnigh any spot on the coasts of the globe, and who have to their hand concentrated and preserved foods, a surer knowledge of the causes of tropical diseases, and outfits of non-perishable medicines sufficient for many years within the space of a few cubic inches. Commissariat and health are the keys to all exploration in uncivilised regions. Wallace accomplished his work on the shortest of commons and lay weeks at a time sick through inability to replenish his medical stores.
