Anniversary Address of the Linnean Society. 801 



tlius opportunities of comparison greatly beyond what in ordinary cir- 

 cumstances fall to the lot of an individual. His library too was stored 

 with almost every important publication that could be required for his 

 undertaking. With such ample materials, aided by his untiring zeal 

 and the persevering energy of his character, he steadily pursued his 

 allotted task, and only ceased to labour at it when he ceased to live. 



"It was not merely as a botanist that M. DeCandoUe deserved well of 

 his country and of mankind. Both as an individual and in the Council 

 of his native city, he was ever active in the promotion of measures of 

 public utility, whether they related to the improvement of agricul- 

 ture, the cultivation of the arts, the advancement of public instruction, 

 or the amelioration of the legislative code. Even in his botanical lec- 

 ture he never lost an opportunity of inculcating the importance of 

 these and similar subjects. Those lectures were attended by a numer- 

 ous class, who caught from their teacher a portion of the enthusiasm 

 with which he was himself inspired. Some idea of the manner in 

 which he brought their subject before his auditors may be obtained 

 from his ' Organographie' and ' Physiologie Vegetale,' published in 

 1827 and 1832, which contain the substance of his lectures on those 

 two great departments of the science. 



" For some years his health had been declining, and it is to be feared 

 that the severe and incessant attention which he paid to the elabora- 

 tion of the great family of Composites had made a deep inroad upon it. 

 As a relaxation from his labours, he undertook, in the last year of his 

 life, a long journey, and attended the Scientific Meeting held at Turin ; 

 but he did not derive from this journey the anticipated improvement 

 in his health, which gradually failed until his death, on the 9th of 

 September last. He has left a son, Alphonse, well known as the 

 author of several valuable botanical publications, one of which, his 

 memoir on the family of Myrsinecs, appeared in our ' Transactions.' " 



Jens Wilken Horneman was born in 1770, and studied at the Univer- 

 sity of Copenhagen, where his ' Forsog til en Dansk oeconomisk Plan- 

 telsere' obtained a prize in 1795. In 1798 he commenced a botanical 

 tour through Germany, France and England, and in 1801 became 

 lecturer at the Copenhagen Botanic Garden. He succeeded his teacher 

 Vahl as Regius Professor and Director of the Garden in 1804, and 

 published in 1807 an ' Enumeratio Plantarum Horti Havniensis, 

 and in 1813 and 1815 a more complete synopsis of the plants there 

 cultivated under the title of 'Hortus Regius Botanicus Havniensis. 

 In 1819 he wrote a dissertation * De indole Plantarum Guineeneium."
