In the science of Horticulture Dr. Lindley has also taken the 

 highest position ; nor is it too much to say, that it is mainly due to 

 his efforts that this branch of knowledge has risen from the con- 

 dition of an empirical art to that of a developed science. In no 

 department have his labours been more widely appreciated than in 

 this ; not only because, up to a very recent period, the ignorance of 

 sound principles and the prevalence of injudicious practice retarded 

 the progress of scientific horticulture, but because these evils could 

 only be remedied by one combining that knowledge of scientific 

 Botany and of gardening operations which he possesses. To these 

 requirements he has added the power of studying the results of 

 experimental research by means of those laws of climate in its rela- 

 tions to horticulture, which had previously been so ably expounded 

 by our late illustrious Fellow, Professor Daniell. In pursuing these 

 inquiries, Dr. Lindley has displayed the same ready facility in ap- 

 plying his varied knowledge to the investigation of difficult problems, 

 which characterizes his works on the affinities of plants. 



I may also briefly allude to Dr. Lindley 's numerous elementary 

 and other treatises on Botany, and on its applications to Medicine 

 and the Arts ; to the long series of illustrated works he has pub- 

 lished ; to his researches in the Fossil Flora of Great Britain ; and 

 to the cordial reception of so many of his writings on the Continent, 

 as is evidenced by the translation of several of them into other 

 European languages. In this award, the Council of the Royal 

 Society further wish to mark their recognition of the great and 

 beneficial influence of Dr. Lindley' s labours, both as an author and 

 Professor, in introducing and diffusing a knowledge of the natural 

 system of Botany, and of Vegetable Anatomy and Physiology, into 

 the Schools and Universities of this country. 



DR. LINDLEY, 



Accept this Medal in token of our appreciation of the labours of a 

 whole life devoted to the successful cultivation and the extension of 

 our knowledge of the sciences of Botany, Vegetable Physiology, and 

 Horticulture.
