The garden has diiriiii* ils existence heen the seat for experiments 

 planned out hy the l)()taiiists or by the garden-curators. Thus curator 

 Mørch tried to feed silkworms with substitiites for the leaves of 

 Moms alba and fonnd, that Ulmiis amcriaina gave the hest result. 

 Curalor W e i 1 b a c h planned out experiments with heavy glass for 

 greenhouses and with air circulation in greenhouses in the purpose 

 to give the i)lants more natural conditions. Dr. Samsø Lund and 

 Kiærskou have carried out investigations upon the cabbage species. 

 In the latter years professor W. Johannsen, C Raunkiær and 

 C. \\. Ostenfeld have planned ditferent expejiments. 



Although we here speak of the garden itself, a few notes about 

 the institutions connected witii it, will be of some valne. The museum 

 enibraces collections of piants in alcohol, samples of wood and seeds 

 and first of all the herbariums. These containing c. 475,000 sheets 

 consist of 3 main divisions namely the universalherbarium, the 

 danish and the arctic herbarium. The library to which admittance 

 can be had 3 times the week, contains c. 20.000 volumes.

About the expiration of the past century an arrangement took 

 place between the Sorø forests and the botanical garden of Copen- 

 hagen in accordance with which the garden should rear trees and 

 shrubs to be planted in the Soro forests on grounds that could be 

 spared. Since 1903 difTerent conifers and a large collection of Cratæ- 

 giis have been planted near „Filosofgangen" while a selection of Acer 

 has been put down in „Feldskov". 



THE BOTANICAL CARDEN OF KIEL') 



The university of Kiel erected in 1665 by the duke Christian 

 Albrecht, received in 1669 from this prince a botanical garden 

 and the planning out of this was intrusted to the medicinal professor 

 Johan Daniel Major. The work he had undertaken lasted about 

 4 years full of trouble and vexations for the poor Major. In 1773 

 another medicinal professor N i k o 1 a u s P e c h 1 i n had to overtake 

 the directorship. The garden soon declined and it seems that it did 

 not exist after the year 1684. 



A new hortus niediciis was shorlly after 1720 erected near the 

 university-building. The apothecary C h r i s t i a n i pledged himself 

 against the payment of 10 Rdl. the year to cultivate the ground and 

 grow different medicinal piants and furnish the professors with mate- 

 rial for their leclures on botany. 



In 1802 a new hospital with surroiding garden was erected in the
