factories, Mr Russel's residence at Mayfield was long 

 known to plant lovers, as showing how much material 

 bustle is not incompatible with strong enthusiasm in their 

 favourite pursuit. Mr Eussel joined the Society in 1867. 

 The Botanical Club, as well as tlie Edinburgh Naturalists'

Dr Kandle Wilbraham Falconer, twice Lord Mayor of 

 Batli, and a president of the British Medical Association, 

 died on May 6, 1881, aged 65. He joined our Society in 

 1837, the second year of its existence, and was then 

 president of the Royal Medical Society. A learned paper 

 " On the Ancient History of the Rose," afterwards printed 

 in the Gardeners Magazine, vol. xv. p. 379, formed one of 

 several papers which he laid before the Society. He was 

 appointed local secretary for Pembrokeshire in 1847, and 

 published anonymously A Catalogue of Tenby Plants, 1848. 



John S. Innes, M.D., a Non-Resident Fellow, died at 

 Forres on 15th April 1881. He joined our Society in 1838, 

 being proposed by the well-known local botanists, Rev. 

 Dr George Gordon of Birnie and Mr Stables of Nairn, 

 doubtless in compliment to his reputation as a passionate 

 cultivator of flowers, especially the rose. Dr Innes was 

 born in Ceylon, but commenced practice in Forres in 1833, 

 and continued there for nearly half a century.
