wood, shaped like a small opera-glass case. It has a silver hoop, 
with the words—“Jac: et Clemen: Dei Gra: Mag: Brit: Fra: 
et Hib: Rex et Reg. Fidei Defensor. 1726.” On the lid is a 
heart-shaped shield charged with a sphere, the ring of which is 
dislocated, and over which is the legend “Spes Ultra.” This 
snuff-box was sent to the Kirkconnell family by the Chevalier 
and his wife Clemeritina through Sir David Nairn, their Secre- 
tary, whose name is imprinted on the bottom. 
Mr Watson, in moving the thanks of the Society be awarded 
to Mr Witham, remarked that the grandfather of the present 
Mrs Witham, James Maxwell, Esq. of Kirkconnell, was an officer 
under Prince Charles Edward, and fought with him in all the 
engagements, and afterwards accompanied him into exile. While 
at St. Germains he wrote the narrative of the Rebellion, which 
was so largely drawn upon by Sir Walter Scott. 
CoMMUNICATIONS. 
I. Atmospheric and other Influences on the Migration of Fishes. 
By Mr J. J. ArmisTEaD. 
The following notes will apply chiefly to the Sa/monide, as 
that family of fishes has come chiefly under my notice. I may, 
however, first remark with regret that the systematic arrange- 
ments adopted for noting the movements of birds by means of 
stations all over the world have not yet been extended to fishes, and 
that our information on many points connected with their habits, 
is therefore still very meagre. It is now almost impossible 
for a flock of birds to cross the North Sea without being seen 
leaving the land on the one side and approaching it on the other, 
and the facts reported to a central committee. But, notwith- 
standing this, some of our commonest birds have not been traced 
to their breeding stations. I might take as an example the knot, 
which is most abundant on the Solway during the winter 
months. We know that this bird goes away to the Arctic 
regions, but we know no more. It is much more difficult to 
follow the movement of fishes, and there is here a wide field 
open for the observer. The more we work out the facts about 
the migration of fishes, the more complex very often does the 
question appear to become. Primarily there were two causes 
which led to their migration—first, food supply ; second, repro- 
duction of species. It has been asserted that salmon do not feed.
