 regarded as if i' wero n fanciful hypothesis. Hypothesis in the 

 abstract, as distinjfuished from any particular hypothesis or hypo- 

 theses, was, of course, what I intended. — S. W. Flannel next to 

 skin as best for bodily health, — therefore better for the mind, — 

 mens snna, &c. For the other trouble there is nothing but resolute 

 will ; which of us has U'lt been troubled that way ? Still, busy work 

 which has also interest for the mind will in the long run chase from 

 us thoughts we hi-ve no wish to entertain.—.!. E. Okill. Pardon 

 me, it is you who have " missed the mark again : " preferring beer 

 to water is not the same as craving strong drink. As the old song 

 has it, when I am hot and tired 



I loves a glass of good beer, 



I'm partikler partial to beer. 

 Yet I assuredly have no craving for it, and for fen years have 

 scarce tasted it. You think few, but, fo far as I can judge, every 

 reader .of Knowledge reads these Answers. — John Rouse. Although 

 the discoveries of asteroids have been rather common of late years.

ingenious ideas of my friend, Professor Kirkwcod, of Bloomingt( 

 Indiana, will he considered. I look upon his discovery respecting 

 the arrangement ol asteroidal distjinces as full of interest. — J. V. E. 

 There are so many articles waiting th.at I fear it would be unwise 

 to invite you to send yours. It would, however, be returned. Nrtt 

 undertaking to return, &c.., is not the same as undertaking not 

 to return. — E. A. Fk.4xcis. I venture to mention my " Half 

 Hours with the Star."," published by D. Bogue, price 2s. 6d., as 

 likely to help yon. I have no pecuniary interest (never had 

 in fiict) in the sale of the book, or would scarcely mention 

 it. Still, I think it wonld be of use to you.— M. AI. W. We 

 shai-e your views ; but the subject is outside the line we marked 

 in our first number. It is better avoided. 



ELECTRICAL. 

 .I.iSTEs Xelsox Fr.ASER. You need not be afraid of asking ques- 

 tions, simple though they be, more particularly if they are such as 

 it is difficult to find a direct answer to in the ordinary elementary 

 text-book. Where specially made zinc is unobtainable, amalgama- 

 tion should always be resorted to. It is a simple process, which you 

 can carry out for a few pence. Get a little sulphnric acid (a penny- 

 worth of oil of vitriol friim the oil-shop will do) and mix with water, 

 in the proportion of one of acid to about twelve or more of water. 

 Place your zinc in this {to remove surface impurities), and leave it 

 until it nearly stops fizzing. Then with the aid of a piece of wool, &c., 

 the zinc being still wet, rub in a little mercury until yon get a 

 uniformly bright surface. If it isn't bright all "over dip it in the 

 water again, and then give it another rub. Don't be wasteful with 

 the mercury. A globule about the size of a pea is amply sufficient 

 for a good-sized plate.— S. Ckosse. The half of the ring nearest 

 the magnet assumes a polarity opposite to that of the inducing pole, 

 while the remote h.ilf assumes the like polarity. The neutral line 

 in this case is the diameter of the ring at right angles with the axis 

 of the magnet. No change is produced by coil copper wire round 

 the stationary iron ring.

THE following game illustrates well tho advantage of under- 

 standing partner's play, or of being assured that partner 

 plays according to some definite plan in particular cases. The hand 

 resembles one described by Drayton, and so closely, that it may be 

 regarded as tho same hand. (It was written from memory of that 

 hand.)

REMARKS, INFERENCES, &c. 



1. A having only three-card suits, 

 outside trumps, and not sufficient 

 strength to justify a trump lead, 

 leads the best card from a short 

 suit. li holding the Knave knows 

 that the lead is not from Q, Knave, 

 ten, or from strength. He infers, 

 therefore, that .-1, who is a steady 

 player, has four trumps, but is not 

 strong enough to lead trumps. He, 

 therefore, having four trumps, 

 leads one, through >;'s King. 



2. A cannot as yet tell whether 

 has led from strength in trumps, 



or, recognising evidence of length 

 in trumps in .-I's hand, has simply 

 through the hi'uour to heli> 

 him. He therefore does not re- 

 turn a trump. 



nd 4. B again plays through 

 the honour ; and now A, seeing his 

 partner must have four at least, 



5. Returns a trump, which draws 

 the King. 



The rest of the hand plays itself. 

 At 8 and 9, Y pl-<ys to clear his 

 partner's suit, but the third round 

 in spades is ruffed. 



We cannot say we altogether 

 approve -4's play. Having no 

 means of knowing whether dia- 

 monds were his partner's suit or 

 one of his opponent's, he should not, 

 we think, have thrown away the 

 Queen ; had the suit been headed 

 by the Knave, he could not have- 

 done better than to lead (he best.

EASY END GAME (Page 174). 

 If Z wins the trick with his small 

 trump, yz lose. Winning with his 

 Queon of trumps, Z leads the 

 three. Y having the tenace over .4 

 wins two rounds of trumps, and 

 leads his winning heart.

Plating with a Bad Partner. — 

 In tho face of the immense variety 

 of the .style of play one may meet 

 with, the only general advico one 

 can give is, as soon as it be- 

 comes apparent that your partner 

 does not understand your own sys- 

 tem, observe his play carefntly, and 

 endeavour to discover what his 

 peculiarities are j and if you find 

 ho has any fixed habits at all, yoa 

 ^^■~~* may in most cases adapt your play 



to them, and so turn them to your joint advantage. It ho cannot, 

 or will not, fall in with your system, you must adopt his, and so 

 endeavour still, in defiance of him, to make some soi t of a com- 

 bination, and avoid tho cross purposes which are so beneficial to 

 tho adversary. Pole.

 sugar from wator-melons, finds that they contain seven per cent, of

 2,415 pounds of sugar could be extracted, worth, at 10 cents.
