ON EARTHQUAKES IN SCOTLAND. 241 
Fifth Report on Earthquakes in Scotland, drawn up by Dr. Bryce, 
F.G.S. The Committee consists of Dr. Brycr, F.G.S., Sir W. 
Tomson, F.R.S., J. Brovcn, G. Forses, F.R.S.E., D. Mitne- 
Home, F.R.S.E., and J. Tuomson. 
Tux period of extraordinary earthquake disturbance in various parts of 
Scotland recorded in last year’s Report has been succeeded by one of entire 
quiescence. Neither in the Comrie district, where the disturbances have 
been in time past both most frequent and severe, nor in other tracts of country 
occasionally agitated, has any earthquake movement been known to occur 
during the year, such as either to excite the attention of any one or to 
affect the instruments. 
The seismometer belonging to the Association, placed in the tower of 
Comrie parish church, is maintained in a state of efficient action, and carefully 
observed from time to time; and a meteorological record is kept in the house 
of a local member of the Committee, whose residence is in the immediate 
neighbourhood. 
As an additional indicator and check upon the seismometer, a set of 
upright cylinders are now to be placed in a separate building arranged as 
suggested by Mr. Mallet, and of the size and form which he recommends. 
A site for this building has been most kindly granted by Peter Drummond, 
Esq., of Dunearn, near Comrie, on the private grounds which surround his 
residence. The distance from the parish church is about half a mile, and 
the site upon a rock through which any vibrations that occur will be freely 
communicated from the supposed centre of disturbance, situated among like 
rocks about two miles towards the N.W. This building is to be immediately 
proceeded with. 
In closing this brief Report the Committee have to refer with the deepest 
regret to the lamented death of Mr. Peter Macfarlane, which occurred in 
June last. Mr. Macfarlane for-many years had charge of the instruments at 
Comrie ; and the Committee have had frequent occasion to refer to his untiring 
zeal and watchfulness in conducting this inquiry, and to speak in terms of 
high commendation of the ingenious mechanical contrivances which he was 
enabled to bring to bear upon the methods of observing. 
Report of the Committee appointed to prepare and print Tables of 
Wave-numbers, the Committee consisting of Dr. Hucatns, F.R.S., 
J. N. Lockyer, F.R.S., Dr. Reynoups, /.R.S., G. J. Stoney, 
F.R.S., W. Srorriswoovz, F.R.S., Dr. De La Ruz, F.R.S., and 
Dr. W. M. Warts. 
Tur work of this Committee is in progress, and the Committee hope to be in 
a position to make a full report at the next Meeting of the Association. 
Under these circumstances they ask to be reappointed,
