myself with my left leg bending, my right leg extended to- 
wards the NW. The preserving the centre of gravity must 
have been divested of error. At the same time I felt exactly 
as in a vessel taking a heavy lurch, and suddenly recovering 
herself. In fact, the whole sensation was that of being in a 
steward’s berth, surrounded by crockery all in motion.” 
It is natural to suppose that an earthquake, which produced 
such effects as those described in the foregoing accounts, 
should have produced no small alarm in the district of Strath- 
earn. On this point, it may be sufficient to quote the testi- 
mony of John C. Colquhoun, Esq., of Killermont, who, within 
a few weeks after the shock, was resident at Lawers and Cla- 
thick. He says that the effects now alluded to “‘ were most 
striking ;—people running out of bed,—flying in Comrie to 
- the meeting-house (though at midnight), and remaining there 
for two hours engaged in devotion,—abandoning all work the 
following day,—a commercial traveller, who felt one of the 
lesser shocks, flying the same night from Comrie,—a dissent- 
ing minister, who had come to officiate, refusing to remain,— 
several women fainting, and an impression of horror seizing 
upon the minds of men of the boldest youth and strongest 
nerve, which completely unmanned them. On the night of 
the great earthquake, not an eye, I believe, was closed within 
this whole valley. The most careless, who were curious to feel 
an earthquake, never speak of them now but with terror.”

Researches on the Structure of Mucous Membranes. 
By M. Frovurens. 
M. Frovurens, at the meeting of the Académie des Sciences on the 29th 
November last, 1841, read an interesting memoir on the Structure of the 
Mucous Membrane of the Nose, Windpipe, and other parts, which we 
now submit to the notice of our readers. 
It will be recollected that this is not the first memoir on mucous mem- 
branes which has been presented by the able author. Upon former oc- 
casions, he availed himself of opportunities to explain the structure of 
the skin, both in the fair and dark coloured races of man; also of the 
mucous membrane of the tongue, mouth, cesophagus, and intestinal tube. 
On the present occasion, those of the nose, windpipe, bladder, and arte- 
ries, are particularly dwelt upon.* 
* All these memoirs, in extract, have been inserted in preyious numbers of this 
Journal,—Epiror.
