consisted of undulating oscillations, ixtrorsum et eatrorsum, and rendered 
more evident by the margin of the cup being furnished with fine waving 
fimbriez. The animal gradually thickens from the margin down to the cen- 
tre, and the movements are effected by gentle contractions and dilatations, 
which, when swimming, are alternately stronger on either side as the direc- 
tion of the animal requires, the contractions having rather a spiral inclina- 
tion. The whole is perfectly transparent, at least interrupted only by distant 
tendinous-looking lines rising vertically from its centre. On bringing it to 
the surface it commenced a retreat to the margin of the tank, swimming 
slowly, with its concavity inclining forwards, and then settling at the bottom ; 
on raising it again, and turning up its convex side, it righted itself and sank ; 
on touching it, when at the bottom, it shrank from the touch, and moved 
forward a few inches. Any information on this subject in your interesting 
Magazine will oblige, Yours, &c.—John Brown, FL.S. Boston L., Aug. 22. 
Whether a Fish called the Samlet ever becomes a Salmon or not, is a ques- 
tion not yet satisfactorily answered. I think I could give circumstantial, 
if not positive, proof that it does. William V. Ellis, Esq., of Minster- 
worth, near Gloucester, who has a very extensive fishery on the river 
Severn, is of opinion, from information received from fishermen under 
his direction, that the samlet does ultimately become a salmon, in confirma- 
tion of which, he says, one of the fishermen thrust a wire through the tail of 
a samlet, and in process of time (notwithstanding the corrosion and action 
of the fresh and sea-water on the wire) the same was again taken with the 
wire in its tail after that it had become a salmon.— Thomas Hawkins. The 
Haw near Gloucester, Oct. 21. 1829. 
Whether the Botcher, the Gillon, and the Salmon are merely varieties or 
the same fish, or (as the fishermen here think) distinct species, is a ques- 
tion I should wish solved. I do not know whether these distinctive 
names are local or general, but, by whatever name they are called, I think 
they will be understood as distinct. My own opinion 1s, that they are the 
same fish at a distant period or stage of growth, or varieties only, and that 
the renovating influence of the sea-water is the only difference; but if I am 
wrong, I should wish to be better informed. — Jd. 
A Nidus attached to a Reed. — Sir, 1 shall be obliged by your giving me 
the name of the wonderful architect whose work is represented by the follow- 
ing.sketch. (jig. 19.) It was found attached to a reed, in the inside of the 
roof of a barn at Crimplesham, in Norfolk. The sketch is of the natural size

and colour [grey]. Besides the two coats seen in it, there is a third in the 
centre, but not so deep as either of the others ; and within that six or seven 
hexagonal cells, like those of the honey bee (4’pis mellifica), but not, J 
think, quite so large. The material of which this curious nidus is formed, ap-
