450 BIOGRAPHICAL SKETCHES. 



tive, Heer was for most of his life an invalid, suffering from 

 pulmonary disease. For the last twelve years his work was 

 carried on at his bedside or from his bed, assisted by a de- 

 voted and accomplished daughter ; he seldom left his house, 

 except to pass the last two winters in the milder climate of 

 Italy. Last summer, having finished his "Flora Fossilis 

 Arctica," in the hope of recruiting his exhausted strength he 

 was removed to the most sheltered spot on the shores of the 

 Lake of Geneva, but without benefit. He died at Lausanne, 

 at his brother's house, on the 27th of September, 1883. It 

 has been well said of him, in a tribute which a personal friend 

 and fellow-naturalist paid to his memory, that " a man more 

 lovable, more sympathetic, and a life more laborious and pure, 

 one could scarcely imagine." 



Heer was elected into the Academy in May, 1877. He is 

 botanically commemorated in a genus of beautiful Melastoma- 

 ceous plants indigenous to Mexico.
