16 Mn. GEORGE HUMPHREYS Account of tbe 
* I am exceeding forry this fhell is broke, as I think I never 
* met with the fort before: it had the fifh in it, and I think it 
* js as wonderful a thing of the kind as ever I faw. After I had 
& taken it out I was endeavouring which way to preferve it, but 
*€ found. I.could. not fucceed, as it was of fuch a flefhy fubftance. 
: “On opening it I found the infide to refemble a fowl’s; it had a 
* diftinét heart, liver, and this that I have fent, which I take to 
* be the gizzard, as your Grace will fee by a little fhell going into 
‘ the infide.” 
The Bulla and gizzard here mentioned I purchafed at the fale of 
her Grace’s Mufeum for Ifaac Swainfon, Efq. of Frith-ftreet, Soho; 
and with his permiffion have the honour of fubmitting them to 
the infpection of the Society, together with another gizzard of the 
fame kind, having the parts feparated; accompanied by a coloured 
drawing of the whole, done by Mr. Lewin; which laft I beg may 
be added to the colleétion of the Society. 
The animal of all the fpecies of the Bulle that we are acquainted 
with is very large, confidering the fize of their teftaceous part, and 
but a {mall part of it can be contained in the fhell; Linnzus fays 
it is. of the limax or flug kind. 
That the part called the gizzard is for the purpofe of aa tticat- 
ing its food, may be inferred not only from the fhell found within 
that fent by Mrs. Le Coque, but alfo from an obfervation fince 
made by John Smith Budgen, Efq. a gentleman very converfant in 
fhells, who informed me, that from a gizzard of an animal of this 
kind he took a {mall fhell, Bulla cylindracea of Pennant, with the 
animal in it. 
The {hell found in the gizzard of Mrs. Le Coque’s Bulla is a 
-{mall bivalve of the Mya genus of Linnzus; and which alfo ac- 
companies the other fpecimens. It had the animal in it when taken 
out. On one of its valves there is the commencement of a circu-
