cassytlia africana, Enceplialartos Lemarinellii, Eulopiiia Liibersii, Coffea 

 Laurentii and several others. — G. H. 



Congress held in Paris, 1901 {Jour. Soc. Nat. Hort. Fr. p. 726). 

 — Amongst the subjects discussed, the most interesting was in the class 

 of "Monographs on a single Genus of Plants," a most able paper on 

 Lilacs and Ligustrinas, by M. L. Henri, professor at the National 

 School of Horticulture, Versailles, and Chef des cultures at the Jardin 

 des Plantes, Paris. It gives a most careful synopsis of all the known 

 species in cultivation, or known only from herbarium specimens, and 

 a valuable record of M. Lemoine's and others' labours in the production 

 of the new double Lilacs and the improvement in colour of the singles. 

 His own work amongst them (BreitscJnicideri) is also modestly recorded. 

 A capital monograph. — G. P.

Cornu, Professor Maxime. By M. P. Harlot {Jour. Soc. Xat. 

 Hort. Fr. p. 421). — A brief appreciative memoir of M. Cornu, since 1884 

 in the chair of Culture at the National Garden of the Jardin des Plantes, 

 Paris. His fame as a botanist was acquired in his work amongst 

 cryptogams, but he did good service in reorganising the gardens, inside 

 and out, and in fostering the distribution to French colonies of economic 

 plants. He seems to have made successful efibrts to bring into closer 

 relations the National establishment and the Horticultural Society of 

 France, as well as lending aid to commercial horticulture in that country.

 methods frequently employed for uprooting them, and the surest and 

 most eftective means for disposing of each of them. — W. C. W.
