PALAEOLITHIC IMPLEMENTS—LARGE AND HEAVY EXAMPLES. 101 gether with one found by me at Hill Head, which also weighs 2 lbs. Implements weighing between 2 lbs. and 1 lb. are uncommon, but too much space would be occupied in giving an enumeration. Butt-ends often give a clue to implements which were large and heavy when perfect. Amongst many other large examples I have a butt-end from Chard which weighs 2 lbs. 83/4 ozs. Certain flakes also tell a similar tale of heaviness. Amongst a large collection of specimens, I have a ponderous outside flake from Madras, which is rudely trimmed to form a horse-shoe-shaped imple- ment, and which weighs 3 lbs. 13 ozs. The Madras implements mentioned above were all found by natives at a place near Tirupati, a town 83 miles from Madras, and a station on the N. W. line of railway from Madras to Bombay. The place is sometimes entered as Tripetty on the maps.

The "Essex Times" thus alludes to the presentation :—"At Cambridge on Saturday, in the presence of the Prince and Princess of Wales and the Royal Princesses, honorary degrees were conferred on Prince Albert Victor and a number of distinguished men. Among these latter was Lord Rayleigh, M.A., F.R.S., upon whom was conferred the degree, honoris causa, of Doctor in Science. In the Public Orator's Latin presentment, Lord Rayleigh was welcomed to Cambridge, where he was lately so well known as Professor of Experimental Physics, and where his recent province of work, the Cavendish laboratory, was ever associated with the munificence of his grace the Chancellor. The Orator alluded to Lord Rayleigh's researches into the motion and resistance of fluids (especially in regard to drops and jets), to his explanation of the blueness of the sky, to his brilliant discoveries in optics and acoustics, and to the happy way in which he had shown that the same principle could often be applied to the elucidation of apparently diverse phenomena. He had a profound knowledge of mathematical theory with consummate skill as an experimentalist, as well as with that common sense which is proverbially so far from common." Abnormal Deposit of Dew.—On Saturday, July 14th, I was surprised to find a heavy deposit of dew on the grass at noon and during the afternoon. I had previously noticed the entire absence of dew, but on walking through some thick grass about noon, I found large dew drops hanging from every blade near the ground. The weather had, as we all know, been unusually cold up to Friday, the 13th ; but on Saturday morning the wind sank, and we had an oppressively hot afternoon with thundery-looking clouds. The cause I presume was that the ground being colder than the air, the moisture condensed near the former, but I have never observed the phenomenon in the daytime before, and should be glad to hear if others have done so.—Reginald W. Christy, Boyton Hall, Rox- well, July 16th, 1888.
