Botanico- Geographical Exhibition at Copenhagen. 419 



geograpliico-botanical regions. He easily accomplished 

 this. The State and other public botanic gardens of 

 Copenhagen rendered ranch aid ; but his success was 

 mainly due to the aid of amateurs and nurserymen. The 

 floras of the Old and New World were clearly demarcated ; 

 and each subordinate botanical province was kept separate. 

 Particular attention was paid to labelling ; it was found 

 expedient to use different colours to indicate varied lati- 

 tudes. Again, the Latin and vernacular names of each 

 plant exhibited were given, as well as the name of the 

 first describer, together with information as to its capa- 

 cities of resisting extreme temperature and its economic 

 uses. The Eoyal Geographical Society of Denmark held 

 several conferences, and the exhibition presented special 

 features of botanico-geographical interest, particularly in 

 capital representations of the Cape flora, as well as that of 

 Japan, New Holland, and Central America. The Exhibi- 

 tion was very popular, drawing crowds from the provinces 

 as well as from the Danish capital. The familiar room- 

 plants were found at once to possess fresh interests, giving 

 in this new method of grouping unlooked-for educational 

 training. The Copenhagen school boys in especial were 

 amongst the most marked visitors to the Exhibition, and 

 at its close a handsome surplus of admission money had 

 accrued, which was handed over to the committee of the 

 Gardeners' Mutual Benefit Society. 



Professor Hansen claims no novelty for his idea. Indeed, 

 the researches necessary to work it out, only the more 

 thoroughly convinced him " that there is nothing new 

 under the sun." At Kew the floras of the old and new 

 worlds are distinctly and separately illustrated. At 

 Edinburgh, too, as well as in the botanical gardens of 

 Brussels, Innsbruck, and Munich, the alpine plants are 

 arranged according to their geographical provinces. In 

 the Botanic Gardens of Copenhagen the Danish flora is 

 demarcated from that of North America ; while in the 

 garden of the Eoyal Danish Academy of Agriculture 

 separate sections are given to the plants of Greenland as 

 well as those of Japan. Since 1885 the " Colinderies " of 

 London have demonstrated the idea on the gigantic 

 scale. But the Professor only argues for modest ex-
