^'^ PROCEEDINGS OF THE ACADEMY OF [1888, 



In Glasgow he was the guest of Dr. W. J. Hooker. Among these 

 whom he met in England at this time were George Bentham, Roht. 

 Brown, Balfour, Lindley, Boott, Bauer, Lambert, Greville and a 

 vscore of others. Upon finishing his work in England he went to 

 the Continent pushing his undertaking with great vigor. In the 

 course of his extended tour he visited Paris, Lyons, Vienna, Munich, 

 Geneva, Halle, Berlin, Hamburg and other cities, and made the ac- 

 quaintance of such men as Jussieu, Brongniart, Decaisne, IVIirbel, 

 Adrien, Gaudichaud, Gay, Delile, Duval, Endlicher, von Martins, 

 Zuccarini, the De Candolles, Ehrenberg, Schlechtendal, Klotzsch, 

 Kunth, Link, Lehmann and many more. 



It will be seen that in this, his first visit to Europe, he made the 

 acquaintance of many botanists already eminent, and others who 

 like himself were later to become so. This was one of the most im- 

 portant years in his life. Acquaintances were made which were 

 life-long ; correspondences were opened and exchanges of plants 

 and works begun which were alike helpful to all parties. It must 

 be admitted that in America Dr. Gray had no equal, but in 

 Europe there were many who were working on kindred problems 

 and to whom he might turn for scientific companionship. L^pon 

 returning home he prosecuted the work on the " Flora" with his ac- 

 customed energy and by the spring of 1841 had issued the first 184 

 pages of Vol. II. 



Passing over ten years of hard work in collecting, writing and 

 teaching at Cambridge, we find him in June of 1850 in a sailing 

 vessel for a second time on his way to Europe. His object now was 

 a study of the plants of the Wilkes Exploring Expedition. 



After travelling in Switzerland, working for a time in DeCandolle's 

 hei'barium at Geneva and visiting von Martins at Munich, he went 

 with Mrs. Gray to the country place of Mr. George Bentham in 

 Hertfordshire and spent two months there, going over in company 

 with Mr. Bentham, the entire collection which had been sent out 

 from America. 



He next went to Sir "NVni. Hooker's house at Kew, London, to 

 study collections there. 



A visit of six weeks to Paris with work in P. Barker Webb's 

 herbarium and at the Jardin des Plantes was followed by nearly 

 four months stay in London with study at the British Museum. 

 Robert Brown was then living. For him Dr. Gray entertained the 

 most profound respect, rating him as he ever after did, as one of the 

 greatest of philosophical botanists.
