of the foundation of the Museum of Natural History, an 

 event which took place that year. In the following year 

 Dr. Oustalet prepared a Catalogue of the Birds collected 

 during the celebrated journey of Prince Henry of Orleans 

 through Turkestan, Tibet, and Western China. Another 

 important memoir followed, ' On the Birds of the French 

 Colonies of Canibodgia, Laos, Annam, and Tonquin/ of 

 which the French National Museum possesses an unrivalled 

 series. We have only lately recorded the completion of this 

 excellent piece of work (see c The Ibis/ 1905, p. 488). 



Besides the above-mentioned publications, Dr. Oustalet 

 was the author of many short papers and notices on ornitho-

 talet was a most kind and obliging friend, and always ready

 Dr. Oustalet died, rather suddenly, at St. Cast (C6tes-du-

 replace him in the post which he filled so well.

 Schulrat" Karl Leverkuhn, by his marriage with Louise 

 Grisebach, a relative of the celebrated Professor of Botany 

 of Gottingen. From 1886 to 1891 Leverkuhn studied at 

 Kiel, Strassburg, Freiburg-i.-B., and Miinchen. At the 

 last-named University he was made " Doctor Medicinse " 

 (May 1891), and after having served as an "Eiujahriger " 

 in the 15th Regiment of Field-Artillery in Strassburg, 

 attained the rank of " Stabsarzt der Reserve."
