22 PEOCEEDINGS OF THE 



Botanical works, though few in number, are weighty, and were all' 

 issued in the publications of scientific societies, with the single 

 exception of his ' Indices Seminum,' which are merely small tracts. 

 In 1833 he was appointed extraordinary professor of botany at 

 Kasan, and three years afterwards he migrated to Dorpat, in 

 succession to Ledebour, a post which he held until his retirement 

 in 1867, when Willkomm succeeded him from that date till 

 1869. 



Whilst holding this seat he next produced the " Eeliquiae 

 Lehmannianse," the first part in the Eiga ' Arbeiten,' and the 

 whole in the St. Petersburg ' Memoires ' in 1868-69. 



His next important work was the ' Anabasearum Eevisio ' in 

 1862, a Monograph of Cousinia in 1865, and then his great work, 

 the elaboration of the Old- World species of the vast genus 

 Astragalus ; this forms two parts, the first in the St. Petersburg 

 ' Memoires ' for 1S68, with a clavis, and the full descriptions with 

 localities in the volume for 1869, thus unfortunately entailing a 

 double quotation. The total number of his botanical productions 

 is stated to amount to thirty-five, besides some of medical 

 interest. Bunge was connected with this country by married 

 relatives ; he was elected Poreign Member of this Society 7th 

 May, 1863. 



William Sweetland Dallas was born in London in 1824. As 

 a boy a love for nature began to mould his life and character, 

 and led him to devote himself to entomology. At an early age, 

 however, family circumstances, consequent on the death of his 

 father, obliged him to seek some definite means of gaining a 

 livelihood for himself, and with this end in view he was placed in 

 a business house in the city. Young Dallas soon found, however, 

 that such a Hfe was altogether uncongenial to him, and he again 

 applied himself to his favourite branch of science. As an 

 example of his industry and of the energy with which he worked 

 at this time, it may be stated that he made a transcript in the 

 reading-room of the British Museum of the whole of Pabricius's 

 ' Entomologia Systematica,' together with a coloured figure of 

 each genus — an undertaking sufficient to have daunted the 

 ardour of many an enthusiast. Encouraged by Dr. John Edward 

 Grray and other naturalists, he was led to contribute papers to 

 the Entomological Society, and for ten or twelve years he was 

 occupied in preparing lists of insects for the British Museum 

 and in writing various excellent compilations, amongst which his 

 ' Natural History of the Animal Kingdom ' is a well known and 

 justly appreciated work. 



In 1858 he removed from London to York on his acceptance 

 of the Curatorship of the Yorkshire Philosophical Society's 

 Museum. The duties of this post he ably discharged for ten 

 years, continuing at the same time his numerous literary engage- 

 ments, and contributing a large number of papers to the ' West-
