migrated to Verviers. Meanwhile he had shown his hking for the 

 OucurbitaceaB by printing two fasciculi of his " Diagnoses de 

 Cucurbitacees nouvelles " in 1876-77, in the Memoires Couronnees 

 of the Belgian Academy. The year 1881 was signaHsed by his 

 monograph of that order, which appeared as the third volume of 

 De Caudolle's ' Monographs ' ; he published a few papers on these 

 plants in following years, and on the Melastomacese, of which order 

 he drew up an account wliieh constituted the seventh volume 

 of De Caudolle's 'Monographs ' in 1891. Whilst at Yerviers he 

 acted as Yice-Consul for Brazil ; he also produced the account of 

 the Melastomacete in Martius's ' Flora Brasiliensis ' from 1883 to 

 1888, the Cucurbitacese in 1878, and the Orchidacese from 1893 

 to 1906. On the 24th May, 1900, he was elected Foreign Member 

 of the Linnean Society, and in 1903 received the diploma of Doctor 

 from the University of Heidelberg. 



In 1901 Cogniaux retired from his chair at Verviers on a 

 pension, which enabled him to devote the whole of his time 

 to botany on settling at Genappe. His ' Dictionnaire icono- 

 graphique des Orchidees,' from 1896 to 1907, chiefly from culti- 

 vated specimens, is a useful work, but its use is restricted by an 

 awkward shape and the method of issue. Soon after this was 

 started, he began his ' Chronique Orchideenne, Supplement 

 mensuelle,' from 1897 onwards. 



His latest completed work was on the Orchids of the West 

 Indies, which came out in the sixth volume of Urban's ' Symbolae 

 Antillaufe ' in 1909-10. 



After this he returnerl to his former love, the natural family of 

 Cucurbitacete, and, in spite of declining health, he had completed 

 the first volume of his revision, when death overtook him, as 

 previously stated. [B. D. J.] 



Wilfrid Omer Cooper, who was killed in action in France in 

 September 1916, was one of our youngest Fellows, his election 

 taking place on the 16th of the previous March, and formally 

 admitted 6th April following. From a boy he was devoted to 

 field zoology, and though his early education was under a tutor 

 and not in any school, he developed into a naturalist, relating his 

 field notes in the pages of the 'Zoologist' and using his micro- 

 scope in the modern manner. 



Although he came of an eminently peaceful family, at the 

 outbreak of the war he was convinced that he must join ; his 

 papers for a commission having been mislaid, he joined as a private, 

 and though later selected as a candidate for lieutenant's rank, his 

 death cut short that intention. He was described as just the man 

 to lead his men : a splendid disciplinarian, resourceful, quick to 

 note events, and tenacious. 



Born in 1895, he was only in his 22nd year when his life, so full 

 of promise as a naturalist, was ended.
