In Borneo some of the natives are said to live in trees, and Mr. Chalmers, in his book on New Guinea, tells of a number of tree houses that he visited on that island. These huts, which are built near the tops of very high trees, are used for look-out purposes, or as a place of refuge for women and children in case of attack. They are perfect little huts with sloping roofs and platforms in front, to which extends the long ladder, by means of which the natives reach the huts. Mr. Gill describes one of these houses which was used as a residence. He says it was well built, but that it rocked uncomfortably in the wind. PROTYLE. The address of Professor William Crookes before the British Association, upon the "Genesis of the Elements," is one of the most important contributions to chemical philosophy that has been published for a long time. Reasoning from the recently discovered law of periodicity among the elements, he discusses the possibility of their being formed from the cooling of one primitive form of matter, which he calls _protyle_. While he admits that we have no direct evidence that the elements are different manifestations of the same form of matter, yet he thinks that the observed phenomena of chemistry and physics point very strongly to such a conclusion, and agrees with Faraday, that, "to decompose the metals, then to reform them, to change them from one to another, and to realize the once absurd notion of transmutation, are the problems now given to the chemist for solution." We consider Professor Crookes to be one of the most eminent scientists now living, and any views he may advance are entitled to serious consideration.--_Popular Science News._ THE KEELEY MOTOR, at Philadelphia, which has long been regarded as a visionary or deceptive enterprise, is coming out now with the endorsement of engineers who have witnessed its operation and say that it develops a new power which cannot be accounted for by any of the known laws of dynamics. It may, however, be a long time before the proper machinery can be invented and constructed for bringing this power into use. HUMAN ANOMALIES, MOUNG PHOSET, MAHPHOON, AND THE GIANT WINKELMEIER. [Illustration: MOUNG PHOSET.] [Illustration: MAHPHOON.] Every departure from the stereotyped plan of humanity is an interesting proof of the vast capacities of nature, and therefore a prophecy of possible variation and grander development for the coming generations; hence the hairy family--Moung Phoset, his mother, Mahphoon, and the giant Winkelmeier--are deeply interesting to the anthropologist. WINKELMEIER, according to the _London Standard_, is now in London at the Pavilion, standing _eight feet, nine inches high_, a foot higher than Chang, the Chinese giant, and evidently the tallest man living. He was born in 1865, in Upper Austria. Neither his four brothers, parents, nor grandparents, are unusually tall. He is healthy, strong, and intelligent, and is expected to continue growing.
