134 NOTES—ORIGINAL AND SELECTED. off and the other begins, but in an examination of Mid-Glacial Gravel extending over some years, I have never come across striated stones, whilst these are very common in the Boulder-Clay, a circumstance also implying the absence of an abrading ice-sheet. In Mr. S. V. Wood's paper on "The Newer Pliocene Period in England," (Quart. Journ. Geol. Soc. vol. xxxvi. 1880), he gives several illustrations of the quiet deposition of Boulder-Clay on Mid-Glacial Gravel, and on pages 4S6 and 487 of the volume cited the following passage is to be found : "There can, I think, be no question that these instances show that by some means the moraine of which the clay is composed was introduced tranquilly over a sea-bottom in which sand and gravel had up to this time been accumulating." J. French. Felstead, June 13th, 1891. NOTES—ORIGINAL AND SELECTED. Badger at Asheldham.—While rabbit shooting the other day over the Asheldham Hall estate, Mr. J. T. Gale and party unearthed a fine badger. It is many years since a badger was caught in the Dengie Hundred.—" Essex County Chronicle," May 29th, 1891, Another Rorqual in the Crouch River.—On the morning of the 7th April, the men on board the "Jumbo" (s.) saw a whale, which they said was about fifty feet in length, almost at the same spot where the one was captured in February, near the mouth of the Roach. Some men at work in that river had heard it blowing during the night. It was subsequently seen distinctly by several persons on the sands at the mouth of the Crouch, and is said to have been stranded, but when the tide returned it made a successful departure from this almost inaccessible position.—E. A. FITCH, Maldon. A Swallow's "pendent bed and procreant cradle."—In the "Essex Herald" for June 9th, it is stated that a pair of swallows have built their nest on the knot of a rope carried from one rafter to another in a workshop in the village of Blackmore. The nest hangs in mid air. Homing Instinct of Hyla arborea, L.—Our member, Mr. E. N. Buxton, writes as follows to the "Zoologist" for June :—" wo and a-half years ago I put a small green frog (Hyla arborea) that my daughter brought from the South of France, into my conservatory here (' Knighton,' Buckhurst Hill). In the following spring he began to croak and, contriving to make his escape, found his way to the pond where his strident voice awoke the echoes every summer evening. He always remained about the same spot, which was about three hundred yards from the conservatory. Now comes the extraordinary part of his history. When the winter came on, he found his way back to the conservatory. This performance he repeated last year, and now again he has found his voice. That so small a creature should remember where he had been comfortable in winter, and find his way back to the conservatory across an open lawn, seems to me very extraordinary." Sea Lamprey in the Colne.—I saw lately a very fine specimen, weighing about four pounds, of the Sea Lamprey (Petromyzon marinus) which had been
