sible here to give even a list of his scientific publications. Besides 104 papers registered in this Society's Catalogue of Scientific Papers,' he produced many works of exceptional value. Amongst them the most notable are the Fragmenta Phytographia Australiæ,' begun in 1858 and concluded in 1882, comprised in twelve volumes, a work teeming with critical observations on Australian plants which have been embodied by Bentham in the Flora Australiensis'; the 'Eucalyptographia,' a revision of the Gum-trees of Australia, with 129 illustrative plates; the 'Iconography of Australian Salsolaceous Plants,' with 90 plates; the Acaciæ and their Allies,' with 130 plates; the 'Myoporinese,' with 74; and the 'Plants of Victoria,' a fragment, with 90. The descriptive portions of these works leave nothing to be desired from a scientific point of view, and the plates, all in quarto, abounding in anatomical analyses, and executed altogether in the Colony, rival the best of those of European botanical works. In 1882 he published his Census of Australian Plants,' in which the ranges of the species in the several Colonies are given, thus initiating a botanical geography of the continent. A second edition appeared in 1889. From his first years in Australia, Mueller had entertained the ambition of writing a Flora of that continent, and when the several Colonial Governments acceded to the representations of Sir W. Hooker that such a work should be undertaken, and had voted the supplies for its execution, the name of Mueller was naturally the first to be suggested as author. And he no doubt would have been selected but for the fact that without constant access to the Australian collections in the British Museum and at Kew it could not be accomplished. Mueller at once grasped the situation, and, hearing that Bentham had been selected as author, he generously offered the use of the whole of his materials, including that of his immense herbarium, which he transmitted, by instalments, to Kew for the purpose. This great work, commenced in 1863, was concluded in 1878, Mueller loyally aiding by correspondence from beginning to end. Happily his collections were returned to him without the loss of a specimen. Of Mueller's works in economic botany the most important is the 'Select Extra-tropical Plants, suitable for Industrial Culture or Naturalisation in Australia.' This work is remarkable as a monument of botanical erudition, and, as an economic guide, it is unique of its kind. It passed through many editions in the colony, has been translated into four European languages, and been reprinted in the United States and in India. Besides being the means of introducing many new cultures into Australia, Mueller's activity in sending seeds of Australian plants, especially trees, all over the world, was phenomenal ; and to him South Europe, Algeria, India, South and West Africa, California, and South America, are greatly indebted for the groves of eucalypti, acacias and other trees that have done so much to adorn their hills and plains, and even to improve their climates. To the Royal Gardens, Museums, and Herbarium of Kew he was a perennial contributor of botanical treasures, continuously for upwards of forty years, often at considerable personal cost. Of this the magnificent specimen of the great fern, Todea barbara, in the Temperate House, is a conspicuous example. It is a native of gullies in the Victorian Alps, from whence Mueller had it transported by wagon to Melbourne, at his own expense, and shipped from thence, as a gift, to Kew. After botany the furtherance of geography was Mueller's constant endeavour. He was President of the Geographical Society of Victoria from its commencement, and author of valuable contributions to its Proceedings. According to a statement in the 'Melbourne Argus,' it was he who induced Sir W. Macgregor to undertake the exploration of New Guinea. He was an active member of Burke and Will's Exploration Committee, and he ceaselessly urged upon the attention of his fellow-colonists the importance of an Antarctic Expedition. No better evidence could be adduced as to the value attached to his own explorations and his efforts in the advancement of geographical knowledge, than that at the Geographical Congress in Vienna he was one of the first to whom a special vote of thanks was awarded for exceptional services in the cause of this science. Amongst other instances of his devotion to science must be recorded the fact that he was one of the three founders of the now flourishing Royal Society of Victoria, which was established within a year of his arrival in the colony. He was President of the Australian Association for the Advancement of Science at its second session, held in Melbourne in 1889, and was an active member of the Horticultural, Acclimatisation, and various other societies of the Colony. It may further be mentioned, that being a discriminating devotee of music, he was chosen acting President of the Melbourne Liedertafel. As with many other men of ardent disposition, Baron Mueller had striking personalities. He is described as being of middle height and frugal habits, dressing in black, wearing wooden shoes, and boasting of never having been possessed of a watch or a lookingglass. He was as voluble in conversation as indefatigable in correspondence, asserting that the latter amounted to 3000 letters annually, written with his own hand. His multitudinous titles, and the decorations with which he delighted to adorn himself, were a source of innocent gratification to him, especially his foreign hereditary dignity of Baron, conferred on him by the King of Wurtemburg; and the K.C.M.G. by Her Majesty on the announcement to the Secretary of State for the Colonies of the completion of the VOL. LXIII. f Flora Australiensis.' He was generous to a fault, devoting the whole of the savings from his official salary to science, charities, and good works. He was elected a fellow of the Linnean Society in 1859, of the Royal in 1861, and was awarded a Royal Medal in 1888. Of other British and foreign scientific societies he held 150 diplomas. He never married. His last and fatal illness was an affection of the brain, of a fortnight's duration, due to study, worry, insomnia, and a total abandonment of bodily exercise. He died in his official residence in Melbourne, October 9th, 1896. J. D. H. INDEX TO VOL. LXIII. Air, Gases in (Ramsay and Travers), 437; new Constituent of (R. and T.), 405.
