[Vol. XXII. No. 567 



stance, experiment 7, coming under the head of "Various 

 Ways of Inducing Chemical Change." The student is 

 told to mix together potassium chlorate, sugar, and con- 

 centrated sulphuric acid, these directions being followed 

 by an interrogation mark, which is presumably intended 

 to elicit from the student an explanation of what has 

 taken place. An exclamation point would, however, seem 

 more suitable after such an experiment ! 



NOTES AND NEWS. 



On Dec. 5 Professor William H. Holmes read a paper 

 before the Anthropological Society of Washington, in 

 which he connected some types of pottery from the ex- 

 treme southern states with that of the Caribs, by means 

 of the peculiar style of ornamentation, observed also on 

 the wood-carving described in Prof. O. T. Mason's 

 pamphlets on the Latimer collection and the Guesde col- 

 lection. In this same connection it is interesting to re- 

 call the observations of Prof. Jeffreys Wyman upon the 

 evidence of cannibalism in the shell-heaps of the St. 

 John's River, east Florida. Professor Wyman first came 

 upon these evidences in 1861 and the results are stated 

 in the seventh annual report of the Peabody Museum, 

 published in 1874. With this bit of evidence, connecting 

 the Caribs with southeastern United States, should also 

 be associated the practice of some southern tribes of 

 weaving a band of cotton or other textile above the calf 

 of the leg so as to increase the size of the limb. This 

 was practised by the Caribs also. Not much weight 

 should be given to the co-existence among the Caribs and 

 the southern tribes of the sarbacan and the blow-tube, 

 because the last-named apparatus might be found wher- 

 ever good straight reeds occur. The Cherokees, the 

 Choctaws, the Chetimachas, the Attacapas, and perhaps 

 some other tribes, make use of this weapon. It is inter- 

 esting to mark that the Chetimachas anticipated the in- 

 vention of the revolving fire-arm by employing the com- 

 poiind blow-tube made by fastening four or more canes 

 together, as the tubes in an organ or pan-pipe. Perhaps 

 no one of these fragments would absolutely identify the 



Caribs with the southeastern Indians, but it would seem 

 strange if a people who could navigate the Caribbean Sea 

 in large open boats were incapable of crossing from Cuba 

 to Florida. 



— Nature announces the death of Baron von Biilow, at 

 Kiel. Von Billow's Observatory, better known, per- 

 haps, as Bothkamp Observatory, was the first in Ger- 

 many devoted to astro-physical researches, and it stands 

 as a splendid monument to his interest in astronomy. 

 By his death astronomical physics has lost one of its 

 most enthusiastic supporters. 



• — Macmillan & Co. will publish very shortly a work on 

 "Mental Development in the Child and the Race," by 

 Prof. J. Mark Baldwin, of Princeton, editor of the Psycho- 

 logical Review and author of the "Hand-Book of Psychology," 

 etc. This book is to be a contribution to genetic and 

 comparative psychology. It will deal in detail with the 

 child's mental growth, and with questions concerning the 

 nature and capacities of the animal mind. Special treat- 

 ment is given to the problem of the origin of the mental 

 faculties, such as Attention, Memory, Speech, Hand- 

 writing, Imitation, Volition. Although the book is to be 

 mainly scientific in its method and results, the author 

 hopes to interest teachers of a psychological turn by such 

 chapters as Educational Bearings of Imitation, Social Sug- 

 gestion, Habit and Accommodation, etc. 



— Wiedemann's Annalen der Physik und Chemie for No- 

 vember, says Nature, contains an interesting paper by R 

 Hennig, on the magnetic susceptibility of oxygen. The 

 method employed, namely, the measurement of the dis- 

 placement in a magnetic field of a short column of 

 liquid in a slightly inclined capillary tube, due to the 

 difference in the stisceptibility of the two gases (oxygen 

 and air) at the two ends of the liquid column, would 

 hardly seem at first sight capable of giving very accu- 

 rate values. The author, however, has olatained very 

 fairly consistent results, and finds the value o •0963 x io~^ 

 for the difference between the susceptibility of oxygen 

 and air at a temperature of about 26° C, and at pres 

 sures varying from 75 cm. of mercury to 328 cm. In
