the time when he first became initiated in the mysteries of geology 
he found this enjoyment infinitely enhanced, by adding to the plea- 
sures he derived from the contemplation of fine scenery, the further 
delight arising from the fascinating study of the subterranean struc- 
ture of the earth, and of the organic remains of a former world. 
From the year 1818, when he became a member of our Society, 
until the infirmities of age arrested his activity, few summers passed 
in which he did not make some excursion to the most instructive 
geological lecalities of England, to enrich his cabinets with stores 
of well-selected organic remains, and follow up the progress of the 
most recent discoveries. 
Dr. Cooke was a near relative of our valuable and frequent cor- 
respondent, Mr. Weaver, and a fellow-labourer with him in his 
researches on the neighbourhood of Tortworth, published in the 
first volume of the second series of our Transactions. He was a 
man of taste, talent and energy, in whom, after early cultivation in 
another school, the ardour of geological pursuits became the ruling 
passion, which, together with all his mental faculties, continued: 
unabated to the last. 
Dr. Du Garp, one of the Honorary Members of the Society, 
maintained during a long life of professional practice in the town 
of Shrewsbury, the reputation of a well-informed and benevolent 
man. Highly esteeming the active cultivators of science, he wel- 
comed them to his home, and threw open to them without reserve 
the stores of his local knowledge. He bestowed continual attention 
to all the geological discoveries in that neighbourhood, and made 
collections both of minerals and organic remains, which he pre- 
sented to the Natural History Society recently established in Shrews- 
bury, among which are some remarkable minerals from the ridges 
of Caer Caradoc, and from the mining tract on the western flank of 
the Stiper Stones. 
I am assured by Mr. Murchison that the geological and topo- 
graphical knowledge of ,Dr. Du Gard were of considerable use to 
him in his, investigation of the Silurian System near Shrewsbury, 
and that its value was much raised by the very friendly manner in 
which it, was invariably communicated., Gn this point, indeed, I can 
myself speak with grateful recollections, for .in the first geological 
tour which I ever made ( 1810), I was indebted to him for valuable 
information, and for minerals from Caer Caradoc, which he pre- 
sented through me to the Oxford. Museum. Dr. Du Gard made 
analyses of several springs of mineral water, near the junction of in- 
trusive rocks with the older sedimentary deposits. Of two of these, 
Prolimoor near Wentnor and Admaston near the Wrekin, he pub- 
lished printed notices. 
Rosert Fercusson, Esq., of Raith, F.R.S. L. & E. & H.S., M.P. 
for the Kirkaldy district of Burghs, and Lord Lieutenant for the 
county of Fife, was elected into our Society in February 1809, 
soon after its formation on the 13th of November, 1807. In 1810 
he was made one of the Trustees of the Society, and placed on. the 
list of our Vice-Presidents, in which office he remained during the
