to combine the natural history of the animals with their anatomy, 
and to found upon the latter a new system of classification. The 
second volume of this work was not published till 1810-14, and is 
occupied with the anatomy and physiology of Birds. In 1813 ap- 
peared the ‘ Anatomy of Acephalous Monsters ;’ and in 1816 his 
great work on the ‘ Anatomy and Development of the Foetal Human 
Brain, together with comparative exposition of the structure of the 
Brain in Animals ’—a classical work, distinguished, like all from his 
pen, by the care, accuracy, and comprehensiveness of the observations 
contained init. Notwithstanding the additions which, since that time 
our knowledge of the earliest development of the brain has received 
from embryology, Tiedemann’s researches have lost none of their 
value, and all subsequent inquirers have recognized the accuracy and 
admired the abundance of ;his facts. In 1817 he published a Mono- 
graph on the ‘Anatomy and Natural History of the Crocodile,’ which 
was commenced as an introduction to a general anatomy and natu- 
ral history of the Reptilia, in conjunction with Oppel of Munich 
and Dr. Liboschitz; but this design, owing to the death of his coad- 
jutors, was afterwards abandoned. 
In the list of Assocrares we have to deplore the loss of 
James Forbes, who was elected on the 17th January, 1832, and 
died at the age of 68, on the 6th of July, 1861. He was born at 
Bridgend, in Perthshire,in May 1773, and commenced life as gardener 
at Dupplin Castle, in the same county. He was afterwards in the 
Marquis of Ailsea’s service, in the same capacity, at Culzean Castle, in 
Ayrshire, whence he went to Ireland, where he lived some years with 
Lord Hartland as steward and gardener. From thence he went to 
the Botanic Garden, Dublin, under Dr. Mackay; and from this 
situation he was appointed head gardener to the Duke of Bedford, 
who required a good botanist and one capable of forming the exten- 
sive gardens at Woburn Abbey, at which place he lived thirty- 
seven years. 
He was an excellent practical gardener, and no mean botanist ; and 
it is mainly, I believe, to him that we owe the ‘ Salicetum’ and ‘ Pine- 
tum Woburnense,’ works, however, in which he was assisted in some 
degree by Mr. Don, formerly Librarian to this Society. The estima- 
tion in which Mr. Forbes’s labours on this occasion were held by bo- 
tanists may be judged of by the following extracts from Hooker’s 
‘ British Flora,’ in which, after speaking of the aid he received on 
the subject of Willows from Mr. Borrer, the author proceeds to say, 
“ But the richest collection of living willows is unquestionably that
