 Lady amateurs appear to be taking an active part in astronomical and microscopical work in Great Britain.
 The temperature of British waters is to be studied with reference to it's influence on the fisheries. The duke of Edinburgh is in- terested in the investigation, which he con siders .-@nst important one.
 To the many uses of glycerine another has been added by SurgeonMajor Cotter, in India. He has found that painting with gly- cerine removes the dryness of the tongue which causes enteric fever patients much wakefulness and suffering.
 More Work for Electricity.-On by one the instruments and processes of our fathers are being relegated to the domain of the antiquated. Now the churn must go. According to French patent, the sage of suitable electric current through milk causes the rapid separation of the butter, and renders churning unnecessary. The manu- facture of cheese and the removal of ran cidity from butter by electrical aid are also claimed
 Earthquake Signaling. Seismo- logical Society of Japan has suggested the use of the surrounding telegraph stations as a means of warning the inhabitants of Toko or Yokohama of the approach of an earth quake. shock at one of these stations could be made to complete an electric circuit and fire gun in either of the two cities, thus civ he o;t minutes before the arrival of the earthquake, and enabling them to ex;inguish their fires and remove many valuables.
 Panoramic Photographs.--A new French apparatus, called the cylindrograph, is designed to photograph at a single opera tion wide sweep of the adjacent country. The instrument consists of camera of semi circular form, with a small lens in the centre which moves on an axis. The dark slide is of some material which will bend, and when view is to be taken the lens is turned upon the centre from one side of the landscape to the other. The panoramic pictures thus se- cured are sufficiently good to serve survey ing, military and other purposes.
 Colors of the Sea.-The theory of Professor ryndall recognizes three principal hues in sea waves-blue, green and yellow. Solid particles held in the water act as min ute mirrors rehecting the light which pene- trates the liquid. The rays which are sent out after having traversed only thin stratum of water preser ve their yellow parts; but if the reflections are attenuated, the water ap- pears green; and if they do not exist at all, the sea being clear and free from the muddy matters, the color is deep blue. Tn an indigo sea the crests of waves will appear green on account of their lack of thickness. Sea-weed, anima lcules and other local or accidental causes may have much influence on the color of the water.
 Why Are We Right-handed 1.-The ab- sence in infants of any mar ked preference for either hand has led 10 the supposition that right handedness is merely a fashio ., in which all are trained; but if so it is a very ancient and very nearly universal fashion. The evil dence of all ages points to it as general among all races. From the time of Aristotle philosophical attempts-none entirely satis- factory-have been made 10 account for this peculiarity of mankind. Professor Buchanan, of Glasgow, has thought it, as well as the equally old and prevalent custom of carrying burdens on the left shoulder, to be due to the lack of symmetry of the body, larger lung and the liver causing the right sice to be heavier than the left, ard inducing greater muscular development of the right limbs. Another theory is founded on the fact that the brain is composed of two hemispheres, which work the muscles cross wise, so that disease or weakness of a hemisphere affects the whole opposite side of the body. Grati- olet and Broca have found that the lobes of the left side of the brain are larger than those of the right, indicating tha. more nervous en- ergy Is directed to the right side of the body than to the left This may be the cause of right t-handedness-or it may be an effect of it.
