[See definition.] The name of a chemist in the seventeenth century. IMG:content-2568.png:[blocks in formation] dipper left no longer any black residue. The oil thus obtained is colorle , highly refractive, smells some what like cinnamon, and has a burning taste. It was valued as an anti-spasmodic and nervous stimulant, but is no longer used in medicine. Taken in exce , it is poisonous. Animal oil is now rectified with sand, water, or lime. Nearly all the animal oil of commerce is now obtained by the destructive distillation of bones, as a by-product in the preparation of bone black. [BONE OIL.] dip'-per, *dip-pere, s.

Astron .: A name given to the seven stars in the constellation of the Great Bear, from their being arranged in the form of a dipper, or ladle. (For peculiarities of this constellation see illustration.) "One of the most notable examples of the constant and yet almost imperceptible changes taking place in our firmament is to be found in the motions of the seven bright stars forming the 'Big Dipper' in the cons tell a tion Ursa Major. Dr. Huggins, the eminent English astronomer, has found by means of the spectroscope that five of these stars are moving in the same direction, with nearly the same velocity, and receding from the earth at the rate of; about twenty miles per second, which seems to indicate that they are a ociated with each other in some mysterious way at present unknown to astronomers. The late Profe or Proctor referred to them as the 'drifting stars,' and this, community of motion, where groups of stars appear to be traveling as systems, he termed 'star-drift, of which there are many interesting examples to be found in various parts of the heavens. After careful and long-continued study of the motions of the seven stars in the 'Dipper' Profe or Flam marion, a dis tinguished French astronomer, has been able to represent the outlines formed by them at various times in the past and those which they will form in the distant future. One hundred you sand years ago, according his ious calculations, the stars now forming the familiar 'Big Dipper' were arranged in the outline of a large and irregular-shaped cro ; and one hundred you sand years hence they will a ume the outline of an elongated and inverted 'Dipper' -very different from the one we now see which will stretch over a large extent of the sky, two to and the the internos convenient dicasuna position of the 'pole star' as they do at present, for there are no 'fixed stars,' and each one of those distant suns, flaming in the immensity of space, is swept along in a movement so rapid that the human mind can hardly conceive it, and almost grows weary even in its contemplation." Profe or Arthur K. Bartlett, in Chicago Inter Ocean, Feb. 18, 1894. 3. Ornith.: Cinclus aquatic us , a genus of birds belonging to the family Merulide and order Pas seres. The bird derives its name from its habit of dipping or bowing the head while sitting, at the same time flirting up its tail. 4. Phot .: An instrument used for immersing plates in upright baths containing nitrate of silver, and withdrawing the same after sensitizing. They are slender, flat strips of hard rubber, wood, gla , por celain, and sometimes silver wire, having short projections upon which to rest the edge of the plate, which stands nearly upright in the bath while the chemical changes take place. dip'-ping, pr. par., a. & s.

Dyeing: A frame on which the fabric is stretched and immersed in dyeing with indigo.
