Special Written Information on matters of personal rather than general interest cannot be expected without remuneration. Seientllie American Supplments referred to may be had at the office. Price 10 cents each. Books referred to promptly supplied on receipt of price. Minerals sent for examination should be distinctly marked or labeled. (1771) G. M. asks : 1. Of what substance to make a capillary tube into which mercury will be attracted. Or of what su bstance to make a three-cornered box in which mercury will be attracted up at the narrow end, and not depressed, as in a glass box? A. There is no substance that will do this to any extent, A box of copper, gold, or other metal that, amalgamates with it, will do it to a very slight extent, but will rapidly contaminate the mercury. 2. In what direction does the earth move around the sun, I mean its yearly motiou, " say at sunrise, what direction is the earth moving in its yearly revolution"? A. In a general sense toward your antipodes; at midday toward the west. 3. Can the north and south polarities of a magnet be isolated from each other in any manner? A. No; they must co-exist. 4. Is there any railroad switch in use in which an open switch is an impossibility, that is one which leaves the main line so that a train could still pass over the open switch without becoming derailed?--a switch that would allow a train to take the side track, but still not open the main line to a train coming from the opposite direction on the main lin. A. Such switches are in nee. 5. Can zinc be soldered; if BO, how? Have tried the usual way, as for tin, but failed. A. Use concentrated muriatic acid as the flux. The spidering takes but slight hold of the metal. 6. Will an uncharged glass jar become charged if it is slipped inside of a highly charged Ley den jar? A. No. 7. How arc small bells made to ring for years by means of static electricity, and without any attention from any one? A. You doubtless allude to the dry pile described in all works on physics. 8. Supposing I touch the outside of a Leyden jar that is charged (but has no coating of foil, nothing but just the clear glass) with one finger of the right hand, and directly opposite of where my finger is, I place a finger of my left hand (inside of the jar), will the glass between my fingers be discharged, and if so, will that particular place become again charged after I remove both fingers? A. You will discharge it, and it will slowly become recharged, but the potential of the jar will be diminished to an extent de* pendent on its relative area. (1772) W. S. H. writes : Henry White Warren, D.D., in his " Recreations in Astronomy," in speaking of the nebular hypothesis, says' " It is a very gnons difficulty that at least one satellite does not re. volve in the right direction. How Neptune or Uranus could throw their moons backward from its equator is not easily accounted for. It is at least one Parthian arrow at the system.. .. A greater difficulty is presented by the recently discovered satelites of Mars. The inner one goes round the planet in one-third part of the time of the latter's revolution/1 Is the nebular hypothesis losing ground with scientists, or is it regarded as probably true? A. It would be a perfect hypothesis that had not a single exception in so vast a scheme as the solar system. The isolation of the outer planets, Uranus and Neptune, by the greatly increasing zones of distance from the central solar influence, may have involved their local systems in perturbation from the tramps of our stellar system, such as we observe in the comets and meteors that come within the limit of our observation. These may be the Parthian arrows that disturb perfect uniformity considering the immeasurable time since the hypothetical commencement of axial revolution in the outer planets, and the vast distance that the whole solar system has traveled through interstellar space since the fiat of creation began, it is wonderfully strange that the system is ae perfect as it is. The aspect of the asteroids points strongly to disruption of a primary planet by impact of a wandering body at a far distant time in planetary history; it, therefore, is reasonable to refer the abnormal position of the orbits of the hatellites of Uranus and Neptune to the same cause; causes for the wonderful velocity of the inner satellite of Mars may be safely ref ered to the relative values of gravity in Mars and its satellite as balanced by the centrifugal force due to the orbit of the satellite. The nebular hypothesis is not losing ground in its relation to gravitation, as the fundamental principle of aggregation and motion, but may become somewhat modified under the advancing discoveries favoring the corpuscular hypothesis. (1773) M. E. asks for a receipt for liquefying solid extracts of opium, also gum opium. A. Water is sufficient, and is the menstruum prescribed by the U. 8. Pharmacopoeia. To make the liquid extract, one ounce of the solid extract is macerated in 16 ounces distilled water and 4 ounces rectified spirit (both imperial measure); filter. It should make up one imperial pint. The alcohol is used as a preservative only. (1774) E. H. O. asks why gray hairs appear in a person's head before reaching the age of 22? And can you inform me of a remedy to bring the hair back to its color? A. No reason can be well assigned; habits of life may have brought it about. It may be hereditary. The color can only be restored by dyeing. (1775) E. L. T. asks if there is any fulminate that will explode at 150 F., or if such a fulminate can be made. A. Such a fulminate can easily be made, but would be exceedingly dangerous, and liable to detonate under very minor disturbances. It would be difficult to indicate one which would explode at exactly that temperature, but it could be made the subject of an investigation. (1776) B. C. H. writes : I have just come in possession of the plunge battery described on page 95 of Queen's Physical Catalogue, 6 cells, carbon plates 5*4X2X, ia pairs, with zinc between. Now will you be kind enough to give me : 1. The internal and external diameter, length, size of wire, etc., that will enable me to construct a coil that shall give the best effect in lifting, charging permanent bar magnets, etc. ? A. The diameter of your coil will be governed entirely by the use to which it is to be applied. The smaller the diameter, the greater the number of turns for a given resistance. For your battery with the elements connected in series use No. 16 wire. With the cells connected in parallel use No. 12. Make the resistance of your coil equal to the resistance of your battery. 2. How should I connect (parallel or series) for strong magnets? A. Connect according to the winding of your coil. If your coil is of coarse wire, connect in parallel. If of the finer wire, connect in series. 3. How for heating wire? A. In parallel. 4. HoW for decomposing water ? A. In series. 5. How for running motor? A. According to the resistance of the motor. 6. How for electro-plating ? A. Three in eries, the two series being arranged parallel. 7. How for incandescent light? A. This depends upon the resistance of the lamp. 8. How for arc light ? A. The battery is too small for an arc lamp. 9. How for charging accumulator? A. Allow two in series for each accumulator. 10. How for operating induction coil ? How for using spark coil? A. This depends upon the resistance of the primary coil. For coils as generally made connect as in No. 6. 11. What can I do to discourage the formation of crystals in the bottom of the battery iars ? A. Use chromic acid or a eolation in which bichromate of soda is used instead of bichromate of potash. 12. Are the crystals bichromate of potassium, and could I, therefore, use them in making new fluid ? A. The crystals are chrome alum, of no value in a battery. 13. What, is the difference in the principles applied in the ennatrnction or ammeters and voltmeters, so that when V nt successively in the same circuit, one will indicate tt* amiwrage, but the other its voltage ? A. Ammeters have practically no resistance. They are placed directly \n tbe main circuit. Voltmeters have very high rsist- ance, and are arranged in a circuit parallel with the armature or the battery. (1777) E. J. S. asks: 1. What " f oot pounds," an electrical term, signifies. A. The foot pound " is a unit of work or energy equal to the work required to raise one pound one foot high. 2 If I can get more light by using 70 volt lampe, or by using 40 volt lamps, with the eight light dynamo, and how many I can have in the circuit ? A. You can get more light with the 70 volt lamps. You can run ten or twelve of them with the eight light dynamo, but its speed will have to be increased. 3. In winding the field and armature, are the number of pounds specified, for single or double covered magnet wire ? A. Double covered! 4. What number and what kind of wire would you recommend me to use for wiring ? A. This depends upon the length of your circuits. Probably No. 10 will do for the main conductors. (1778) C. A. writes : 1. I use for a workshop a room which was foimerly used to store salt meat, and part of floor and wall is saturated with brine, which has a great tendency to cause my tool to rust. Can you give a good and inexpensive remedy for this evil effect ? A. Continual washing will tend to remove the salt from the wood. As a temporary relief keep a box of quicklime in your tool box. This will keep the air dry. 2. Can you give me a good receipt for a coating preparation for tools to prevent rust, one that is cheap and can be applied to tools without warming it or the tool, and adhere well and not feel sticky ? A. Apply good varnish or alcoholic solution of shellac. The application should be made to the hot metal. 3. What coal is best for blacksmithing and what instructions can you give for selecting a good article ? A. Coal with little sulphur or ash and not too rich in bituminous matter. Make a practical trial at the forge. (1779) Queries asks for one or two books from which he can obtain some information and instruct tion about bird staffing. A. We recommend Batty's "Taxidermy and Home Decoration,'1 $1.50; Brown's 14 Practical Taxidermy," $2.50 ; " The Taxidermist's Manual," 50 cents. i f so, how ? Have tried the usnal way. as for tin. hut failed. A. Use concentrated muriatic acid as the flux. The IQldering takes but slight hold of the metal. 6. Will an uncharged glass jar become charged If it is slipped inside of a highly charged Leyden jar! A. No. 7. How are small bells made to ring for years by means of static electricity. and wi thout any attention from any one? A. You doubtle.s allude to the dry pile described in al l works on physics. 8. Supposing I touch the outside of a Leyden jar that is charg..d (hut has no coating of foil, nothing but just the clear glass) with one finger of the riltht hand. and directly opposite of where my finger is, I place a finger of my left hand (iuside of the jar). will the glas8 between my fllJgero be discharged. and if so. will that particuhlf place become again charged after I remove both fingers? A. You will d I.charge it, and it. will .lowly become recharged. but the potential of the jar WIll be dimlnlsht.'Il to an extent de. pendent on it. relative area. ( 1 772) W. S.
