4320 THE ZooLtocist—FEBRvARY, 1875. 
as they are from heavy gales, in sheltered positions, always damp 
and gloomy, and washed by the purest of waters at a mild tem- 
perature,—their reproduction and subsequent development suffers 
but little from adverse circumstances; secondly, the inaccessibility 
of the island of Sark to the ordinary run of tourists, because the 
visitor, under the most favourable circumstances, unless he has 
unlimited time at his command, must put up with some social 
abnegations; but the most noteworthy and encouraging circum- 
stance is that but few of the specimens (the madrepores, I am told, 
have long since disappeared) have any commercial or marketable 
value, and thus few care to remove them. These, like the sponges, 
hydroids, tunicates and some anemones, which contribute to the 
rich and beautiful colouring of the walls, are of little use when 
taken away; besides the transit is irregular, and as preserved 
specimens they are a very poor satisfaction, for most of them are 
evanescent. If it were possible to remove several square yards of 
the walls of the caverns in situ, and maintain their contents in 
perfect health in a well-regulated aquarium, it would be an ex- 
hibition of unparalleled delight to aquariists, and would doubtless 
clear up many undetermined points in Embryology ; but I fear that, 
even with our present successful aquarium management, this is a 
dream too fond to be realized. 
I omit all reference to the flora of Sark or the natural beauties 
of the island,—which in some respects are superior to any of the 
group of the Channel Islands,—because the Editor, who has been 
very indulgent in allowing this paper to stand over beyond the 
period promised, will not consider it within the scope of the 
‘ Zoologist ;? but no one should visit that island without seeing the 
charming and picturesque grounds of the Seigneurie, and it is a 
graceful characteristic not only of the Rev. William Collings, the 
Seigneur of Sark, but also of other proprietors in the Channel 
Islands, to permit the public to have free access to their grounds. 
The gardens of General Huish, in Guernsey, are another noteworthy 
example, of great beauty and variety, and testify to the liberality 
and thoughtful kindness of the owner. 
Mr. E. Guille, the postmaster at Sark, was good enough to give 
me some interesting information respecting the local names of the 
Gouliot Caves, and he furnished me with an original plan drawn 
by himself, which has served to refresh my memory as to details. 
Mr. Peter Guille also rendered me assistance.
