 Paris, in total population of 2,260,- 945, has 20 centenarians, 138 persons over ninety five, GAO over ninety, and 6,386 who have passed the eightieth year.
 Milk is altered both in taste and ap- pearance by the character of the food supplied to the cows. It is colored by madder and saffron, scented by plants of the onion tribe, and changed in taste by such articles as turnips. Certain food may give it medicinal | properties, and milk thus medicated is proposed as a method of treating disease.
 "An@sthetic revelation" is the name which, according to MT. Xenos Clark, has been applied to the sensation of recovery from the an8sthetic effects of sulphuric ether. For one brief in- stant, just before the complete return of consciousness, the subject invariably has an intense perception of what seems to him at the time the true ex- planation of the universe.
 The reported discovery of the "elixir of life" in baths of acetic acid, applied daily, has ,elicited some interesting scientific comments. These demon- strate the biological impossibility of living forever, and show that Scottish physicians have used acetic acid since 1850 for dissolving away dead tissue from diseased joints, etc., and have thus effected some remarkable cures.
 CELESTIAL FIsHING.-Curious and and ingenious are some of the Chinese contrivances for catching fish. In Swatow is used shallow boat, on one side of which is narrow plank painted white, which in the moon- light the fish mistake for water and jump over it into the boat. At Ningpo cormorants are systematically trained to fish; while at Ichang wild animal such as the otter is trained, not to fish, but to frighten the fish into nets.
 WATCHING THE HEART.-A novel case has been brought to the notice of the Paris Academy of Medicine. A mans breast bone was nearly all re- moved, with parts of several ribs, in order to stop the progress of bone disease. The experiment resulted not only in saving the patients life, but has given several physiologists an op- portunity for direct investigation of the living heart and great artery, parts of which have been made readily accessible.
 HEADS IN DIFFERENT RACEs.-Nor- nal human skulls, according to the measurements of Prof. Flower, range in size from POTS cubic centimeters down to 960 cubic centimeters, the largest average capacity being found in race of long, iat-headed people on the west coast of Africa. The Lap flanders and Esquimaux, although small in stature, have very large skulls, the average measurement of the latter being 1,546. The English skull, of lower grades, measures 1,542; the Japanese, 1,486; the Chinese, 1,424; the modern Italian, 1,475 the ancient Egyptian, 1,464; the Hindoo, 1906.
 ASTRONOMICAL PHoToGRA ApHY.-The first daguerreotype of the moon was taken by Prof. J. w. Draper, of New York, in 184O; the first of the sun by Foucault, of Paris, in 1845; the first of the stars by Prof. Bond, of Harvard college, ill 1850; the first of a solar eclipse by Dr. Busch, of Koenigsburg, in 1851, and by Prof Bartlett, of West Point, N. r., in 1854; the first photograph ot the spectrum of the ecllpsed sun by Prof. Schuster and MT. Lockyer, of England, in 1882; the first of nebula by Dr. Henry Draper, of New York, in 1881; the first of the spectrum of star by Dr. Huggins, of London, and by Dr. Draper, of New York. "Since the first successes" re- marks Prof. E. s. Holden, "there has been an enormous advance in every way. The greatly increased sensitive ness of the modern dry plate has been powerful aid"
 A DELIGHTFUL RECREATIoN.-"Whe youngster," says MT. Matthieu Will Hams, "I amused myself by making saturated solutions of alum in hot water, placing cinders, etc., in these, and setting them aside to cool. The cinders became coated with beautiful crystals, and appeared like choice mineral specimens. Baskets and other devices in covered wire were similarly coated. Sugar was crystallized, beau tiful crystals of sulphur, made by slowly evaporating a solution of sul- phur in bisulphide of carbon, and au- other form of sulphur crystals by fusing sulphur in c, ucible or galli- pot, breaking the crust which first forms on cooling, and then pitching out the liquid. A nest of beautiful crystals remains. refer to these crudities in order to suggest that crys- tai making should be re-instated as a popular scientific recreation.
