 SCIENTIFIC MISCELLANY.

account, it is suggested, of breathing dry hot air
 In the Vienna General hospital man lately died from cancer who had been infected with trichino- sis twenty five years before, and whose body con- tained trichine estimated to number 4,OOO 100000.
 An official report upon one of tho most disas- trous boiler explosions on record attributed the accident to the ignition of coal gas that had col- lected in the hues. Recent observations show that explotive gas is sometimes developed in steam pipes.
 The American Association for the Advancement Of Science meets this year at Toronto from August p to September 8; the British Association at Newcastle-on- Tyne, September 11.17; the French Association at Paris, August s-15. Great meetings are expected.
 In his work on Baku and its oil, MT. Charles Marvin states that in 1886 single well spouted as much as ll,OOO tons of petroleum per day-an amount equal to the aggregate daily yield of the 5000 wells of America, the thousands of wells in Gallicia, Roumania and BuImah, and the shale oil distilleries of Scotland and New South Wales.
 TE GREAT GLoBE.-The immense globe for the Paris exhibition represents the earth on the scale of one millionth, and is nearly ore hundred feet in diameter. Details are given true proportions, Paris occupying about third of an inch. All the great lines of communication by land and sea are shown in detail. The earth's daily rotation may be precisely initiated by clcck-work, point on the globes equator moving an eightieth of an inch per second.
 AN INTERESTING PHENOMENON The study of the luminous night clouds which, since 1885, have been visible in Europe in the months Of June and July, Is urged by Herr O. Jesse of the Berlin Astrono- mical Observatory. Their periodic movement and great height suggest that they manifest the activity Of cofmical forces, and that they may throw light on the question of a resisting medium in space and on that Of the forces which operated in the early development of the planets.
 REvAccNArIox.-The practical stamping out of small-pox in Germany, according 10 Dr. Hervieux of the Paris Academy of Medicine, has only been accomplished thr rough revaccination. Vaccination lessens the freque ncy and severity of epidemics, and revaccination tends 10 make them disappear completely. Revaccination should be practiced every ten y ears, and should be performed at once when epidemic is threatened, even though but 6 short time has elapsed since the last operation. Hu man or heifer vaccine may be used
 EDIBLE FLOWERS The flowers of an Indian tree MT. P. L.. Simmonds, F. L.. S., as being most remarkable on account of their large proportion of sugar, which reaches 63a per cent They fall of and cover the ground, single tree yielding many hum dredweights of corollas These form-both fresh and dried-a staple of food in many places and, as a rule, eaten once or twice day by the poorer classes of the wild tribes of central India and in parts of Rajpootana, Bombay and Bengal
 BRITISH RABIEs.-Doubts as to the success of inoculation 8 means of combating hydrophobia, and the question whether in some fatal cases the disease has not been produced by the remedy, will long continue to give interest to statistics ing the operation of this method of treatment. A late parliamentary report states that in 1887 sixty four persons were sent from Great Britain to the Pasteur Institute for treatment for rabies Of these i've died, but the victims had all been bitten by dogs unquestionably rsbii, and in three cases the wounds were not cauterized. In 1888 Pasteur treated twenty British subjects, with deaths
 ANIMAL LocoMorIoN.-Since 1872 instantaneous photography has given more accurate ideas of ani- maj locomotion than were held previously. In a lecture on this subject at the Royal institution, London, Mr. E. Muybridge illustrated by moving pictures the interesting fact that all quadrupeds except the camel walk in the same manner They support themselves first on two feet, and then on three. The two may be either both on the same side or one on each side. When the former, the
