. Examination of Two Sounptnes obtained in 62 and 68 
Faruoms respectively, LatirupDE 41° 52’, LoneiTupE 
9° 8’; and the Discovery of Buccan TEETH in the 
Genus Firora. By Joun Denis Macponatp, M.D., 
F.R.S., Staff-Surgeon H.M.S. “ Lord Warden.” Com- 
municated by the Director-General of the Medical De- 
partment of the Navy. 
THE soundings obtained as above were first closely in- 
spected with a pocket lens, after which they were washed in 
a saucer of sea water, the delicate objects being cautiously 
removed with a camel hair pencil, and noted as follows: 
1. A minute triangular crab (Maiade), invested with 
sponge, and still living, though the carapace has been so 
injured as to expose the internal organs. 
2.. A small Madiola, with yellowish-brown epidermis, orna- 
mented with filiform appendages, was detached with its 
byssus entangling numerous Foraminifera and one little 
spiral univalve. 
3. A minute Crania (Brachiopoda) upon the dead valve of 
a Balanus. In this specimen, which was smaller than the 
head of an ordinary pin, no cilia were observable on the 
tentacula (the cirri of the authors), though invested with a 
distinct epithelium. 
The puncta of the orange-coloured shell were frequently 
branched, and in some instances appeared to intercommu- 
nicate. It was probably the young of Crania anomala. 
4. The shell fragments of a recent Lima-shaped Terebra- 
tula. 
5. The jointed cirrus of an encrinite, evidently detached 
from the living animal by the contact of the lead. 
6. Numerous living Foraminifera. 
Considering that the whole area of the arming of the lead 
could scarcely have exceeded an inch and a half in diameter 
in the present case, if a swab had been attached to the line 
the result would have been proportionately more satisfactory. 
In the year 1852, when H.M.S. “ Herald,” Captain (now 
Rear Admiral Sir) H. M. Denham, F.R.S., was at anchor on 
the Victoria Bank, off Cape Frio, many objects of interest 
were obtained by sweeping the bottom, as it were, with 
ordinary swabs. This principle has been most successfully 
applied by Staff Captain Calver, of H.M.S. ‘ Porcupine,” 
by attaching ‘‘ hempen tangles” to the dredging apparatus. 
A subsequent sounding in Lat. 42° 13’, and Long. 9° 1 
(67 fathoms), proved to be a dark, slate-coloured ooze, loaded
