28 THE entomologist's record. 



But in the meantime no fewer than eighteen important papers were 

 brought out in the Journals of the Linnean, the Zoological and 

 Entomological Societies, and twelve articles to other scientific 

 periodicals, all dealing with some of the special results of his collecting 

 and observation. Among those papers contributed to the last named 

 Society were the following : — 



On the J'ieridae of the Indian and Australian Regions, 1857. 



A Catalogue of the (^etoniidac of the Malayan Archipelago with 

 descriptions of New Species, 1868. 



Notes on Eastern Butterflies, 3 Parts. 1869. 



Description of a New Species of Ornithoptera [O. hroakcana). 1855. 



Letters from the Aru Islands and from Batchian. 1858-9. 



To the pages of the Zonloi/ut he contributed : — 



Letters from Singapore ; Borneo. 1854-5. 



Entomology of Malacca. 1855. 



Observations on the Zoology of Borneo. 1856. 



In the year 1855 Wallace contributed an important paper to the 

 pages of the Annals and Magazine of Natural HiMoii/, " On the 

 Laws which regulate the Introduction of New Species." This was 

 followed by the brilliant and since famous essay published conjointly 

 with Darwin's essay on the subject of Variation and entitled " On the 

 Tendency of Varieties to depart indefinitely from the Original Type." 

 This was published in the Journal of the Linnean Society, in 1858. 



In 1864 he published a very long and important memoir in the 

 same periodical entitled " The Phenomena of Variation and Geo- 

 graphical Distribution as illustrated by the I'apilionidae of the Malayan 

 Region," which, perhaps is one of the finest pieces of special pleading 

 ever written in support of a theory. 



The year 1871 saw a collection of some ten essays published 

 previously in various reviews, re-issued under the title of Natural 

 Selection, including " Mimicry and other Protective Resemblances 

 among Animals," and the paper on the Papilionidae of the Malayan 

 Region under another title. The two volumes " The Geographical 

 •Distribution of Animals" appeared in 1876, " Tropical Nature " in 

 1878, " Island Life " in 1880. All contain niHch observation on 

 Insect Life. From that time onwards, Wallace continued to write 

 book after book dealing more and more as he advanced in life with 

 the social problems of the day and the incidence of natural laws on 

 the human race, for whom he had conceived an intense sympathy 

 during his early wanderings as a surveyor. 



The Entomological Society he joined as far back as 1863, and 

 became a Life Member, he was twice a member of the Council, in 1866 

 and 1872, he was a Vice-president in 1864 and again 1869, and in the two 

 following years he was President. He was a Fellow of the Zoological, 

 the Linnean, and the Royal Societies. Our great Universities honored 

 him, Oxford made him a D.C.L., and Dublin an L.L.D. He was the 

 possessor of a Royal Society Medal, awarded in 1868, and in 1876 he 

 was President of the Biological Section of the British Association at 

 their meeting at Glasgow. His signal worth was recognised by the 

 nation in a Pension from the Civil List. 



Full of honors and at a ripe old age, he passed away without the 

 suffering which is the lot of so many when they go "beyond the bar." —
