— The aecond of the papers by Drs. Tambiirini md Seppilll on their cxperiineiital inreatigatloni in hypnotism has appeared in German translntioti by Dr. Fraiikei of Bemburg. The first half of the pwnphlet iB occupied by an account of expcrltnents aod facts obcervsd, while the last half gives their deductions from the facts. The' division made by Charcot, of the phenomena, into those of the lethar- gic, cataleptic, and somnambulistic states, Is accepted, and directions given for producing each of these ststei; but the three candilions are not regarded as in thair nllinate nature different All three are ngarded as due to hyper-excitability of the whote eerebro-ipinal axis, diQerlng among themselves ouly w the irritability is greater or less. One of the argu- moM urged in f&Tur of this view Is from the fact lliat an irritation which will produce at first the le- dii^ic state, will, if iniensilied, produce the catalep- lie, and, upon being made still niore intense, the third tlue, or somnambulistic, characterized by a stifFen- ing of alJ the muscles. The experinienta seem to hare been carefully made, and the pamphlet Is of nil value.

— In the report of Professors Sedgwick and Nichols of the Massachusetts institute of technology, who were Instructed by the Massachusetts board of health to investigate the subject of 'water-gas,' we find that they are averse to the general introduction of this gas for illuminating-purposes. Ordinary coal-giu con- tains about seven per cent of carbonic oxide, where- as water-gas contains as much as thirty per cent. Tble large percentage of poison in the gu would render its introduction, even under the most careful precautions, extremely dangerous to life. In on at- mosphere containing one per cent of coal-gas, dogs, cats, rabbits, and pigeons were apparently able to re- sist the effect of the carbonic oxide almost Indefinite- ly; while, on the other hand, with the same amount of water-gas, death from poisoning generally resulted after from five to eight hours of exposure. Coming from such a source, this report must have much weight In settling this much-vexed question.

— The Influence the merchant may have on science by well-directed efforts Is well exemplified in the career of Godeffroy, who recently died In (iermany, and who was, until lately, head of the great German firm ot traders to the South-Sea Islands. He was, how- ever, says jfature, much more than a merchant. Besides captains and supercai^oes, be sent to Micro- nesia, Meianegia, Polynesia, and especially to Samoa, men of science, whose duty II was to make collections and send them lo Hamburg, to form there an exhaus- tive museum of natural history. The first whom he sent oat on a mission of this kind was Dr. Graefe of Zurich, now inspector of the zoological station ar Trieste, wiio went to Samoa iu 1661, and, from thin as a centre, visited the Fiji, Tonga, and other groups in the region. He returned to Europe after eleven years, bringing with him Important collections, and he undertook the editorship of a Jiyarnal qf the God- ^fffo]/ miueuni. Amongst others thus despatched lo the South Seas, was a lady who spent ten years studying the botauy of northern Queensland, and a Polish surgeon who lived for five years In the Marshall and Caroline Islands, then returned to Europe, returning again to the Carolines, where he is at present. A list of the men employed by God- effroy to travel In the South Seas to study the vari- ous islands, make collections tor bis museum, and report to him, would embrace all national i ties, all dc-
