454 The International Horticultural Exhibition. [July, 
Mr. W. Bull, Chelsea, “On the Relation of Horticulture and 
Botany to Mankind in general ;” Mr. B. Clark, London, “On the 
Floral Envelopes of the Lauracez ;” Dr. Masters, London, “ Double 
Flowers ;” Dr. Hildebrand, Bonn, “On the Necessity of Insect 
Agency in the Fertilization of Corydalis cava ;” Mr. Tuffen West, 
London, “On the Structure of the Testa of the Seed of the 
Solanaceze.” 
It is impossible to enumerate all the public and private enter- 
tainments given. Mr. Veitch gave a magnificent déjewner at his 
exotic nurseries, Chelsea, to the foreign members and English 
botanists, before the formal business of the Congress commenced on 
Wednesday. The most distinguished of the foreign visitors were 
invited to their anniversary dinner, by the President and Council of 
the Linnean Society. A large number were hospitably entertained 
at Kew, by Dr. Hooker. The conversazione at the South Kensing- 
ton Museum was equally brilliant and successful with the exhibi- 
tion, being crowded with visitors, foreign and English, distinguished 
by their rank or scientific position. Upwards of 500 gentlemen 
dined at St. Martin’s Hall, under the presidency of Lord Henry 
Lennox. M. De Candolle and our foreign guests appear to have 
enjoyed themselves thoroughly, having been received with true 
English hospitality. When the most distinguished savans of 
different nations meet together to advance science, which has 
already conferred so many benefits on mankind, each expressing his 
thoughts in the Congress in his own language, may we not hope 
that national animosities and prejudices created for political pur- 
poses between nations will be counteracted, and that mankind will 
continue to advance in the knowledge and appreciation of those 
physical and moral truths so essential to their happiness, and 
which alone can form the basis of a permanent and enduring 
civilization ?
