Notes on a Book of Photographs and Measurements 

 OF PtEMARKABLE AYRSHIRE TREES, presented by Mr. George 

 Paxton to the Library of the PiOYal Botanic Garden, 

 Edinburgh. By Dr. D. Christison. 



The volume that I have the pleasure of presenting to 

 the Library of the Pioyal Botanic Garden, in the name of 

 the author, Mr. George Paxton, furnishes one of the first, 

 if not the first, record of the remarkable trees in a whole 

 county, made by means of photographic views combined 

 with measurements. When Mr. Paxton began to take 

 photographs of the best examples of the different species 

 around Kilmarnock he had not the intention of producing 

 so complete a work ; but, encouraged by the Eev, Mr. 

 Landsborough, he was induced to extend his operations, 

 until he overtook the whole of Ayrshire so exhaustively 

 that probably very few of the larger trees in the county 

 have escaped his notice. 



By. i\Ir. Paxton's request, in presenting the volume, I 

 have drawn up the following brief re%dew of the general 

 results of his labours, and I have also prepared a table of 

 the trees, represented in the volume, showing their localities 

 and measurements, the species being arranged in the order 

 of the size to which they happen to have attained, although, 

 of course, it may be by mere accident that one species has 

 outstripped another in this respect.
