The Paris botanic garden, like many others, has suffered from 

 the effects of the war. Nevertheless the collections were very 

 extensive and of great historical interest because of the many 

 famous botanists who have worked there. Before crossing to 

 England a stop was made in Caen, in Normandy. In the inter- 

 esting botanical institute here, special attention is given to the 

 plants of Madagascar. 



Two weeks were spent at the Royal Botanic Gardens in Kew. 

 The numerous large trees have abundant room for development 

 in the spacious grounds. The collections of tropical and sub- 

 tropical plants give an impression of very great variety. These 

 are supplemented by the various museums. In the herbarium 

 the genera are arranged approximately according to the Ben- 

 tham and Hooker system, the species under the genera by 

 eighteen geographical divisions; Europe, Siberia, Mediterranean 

 region, etc. 



After a stormy passage across the North Sea the Gothenburg 

 botanic garden was visited. This is new and situated among 

 rocky hills well outside the city, it has an unsurpassed natural 

 location.
