Crystallisation. 



Manufacturers on a large scale find that 

 light assists greatly in the formation of crystals ; 

 and one may observe in druggists' windows, that 

 bottles of camphor which are exposed there, are 

 generally covered with crystals on that side 

 which is turned towards the light. To show that 

 the atmosphere, possibly from its mere mecha- 

 nical pressure, has some connection with crystal- 

 lisation, boil two ounces of water upon as much 

 sulphate of soda as it will dissolve, which will be 

 about three ounces. When the water is saturated, 

 pour it, still hot, into a phial previously warmed, 

 to prevent its cracking, and cork it tight. The 

 phial should be nearly full. The liquid, as it 

 cools, will not crystallise; but if the cork be 

 opened, it will immediately solidify, and the 

 phial become warm. Sometimes, upon with- 

 drawing the cork, no change takes place until a 

 crystal of the sulphate or some other angular 

 substance is dropped into the solution. The 

 manner in which this acts in disturbing the 

 equilibrium of the fluid, and causing the forma- 

 tion of crystals, is obscure. After the conclusion 

 of the experiment, you may either repeat it with 

 the same liquid, or boil up the salt again with a 

 little more water, and pour it into a saucer. 

 When cold, throw away the supernatant liquor, 

 and observe the difference of shape between the 

 crystals of sulphate of soda and those of alum. 

 The cause of the phial becoming warm when the 

 salt crystallises, is so curious and of such general 

 application, as to demand a few words. It ap- 

 pears, from experiment, that all bodies, whether 

 solid, liquid, or gaseous, contain in their very 

 substance a quantity of heat which is termed 

 latent, because, under ordinary circumstances, it 

 is not perceptible. That iron contains it, is evi- 

 dent from its becoming hot when struck by 

 another piece as cold as itself. It further appears 

 that gaseous bodies, or vapors, contain more 

 latent heat than liquids, and liquids than solids. 

 Thus, in the preceding experiment, the liquid 

 solution, on becoming solid, parted with that 

 portion of its latent heat, which in the latter form 

 it was unable to retain. 



Contention. 



POVERTY. 



We hope none of our readers are fond of 

 Contention. It is a two-edged weapon, wound- 

 ing when used all who handle it. Hear what 

 the good Bishop Hall says about it, and let us 

 all follow his instructions. His life was a pattern 

 of excellence. " I cannot,nor would I, love those 

 salamanders that are never well but when they 

 are in the fire of contention. I will rather suffer 

 a thousand wrongs than offer one — I will suffer 

 a hundred than return one — I will suffer many 

 ere I will complain of one, and endeavor to 

 right it by contending. I have ever found that 

 to strive with my superior is furious — with my 

 equal, doubtful — with my inferior, sordid and 

 base — with any, full of unquietness." Have we 

 not all, more or less, experienced the same re- 

 sults? And can any one of us bring to our 

 recollection a single instance of any substantial 

 triumph? Well and wisely has it been said — 

 "Leave off Contention, ere it be meddled 

 with." 



Where are now the friends who came 

 Round my board with eager eye ? — 



Fortune shines no more the same, 

 Care is standing grimly by ! 



And I gaze on vacant places, 



Where there should be smiling faces : — 

 Surely Friendship cannot be 

 Scared at sight of Poverty ! '„ 



Where is now the dame I knew— 



Eyes of Heaven, skin of snow ? 

 Love can never be untrue, 



E'en if Friendship serve me so! 

 No! — she'll come that I may borrow 

 From her lips a balm for sorrow : 



Friends may falter, Love will be 



Alike in wealth or Poverty ! 



Friends and sweetheart, quickly come, 

 Cheer me in the hour of ill !— 



Creeping things that deck my home 

 Twine around the ruin still. 



Alas ! Despair the story telleth, — 



" Constancy but seldom dwelleth 

 With such friends as clung to thee 

 Ere thou knewest Poverty !" 



Lone and stricken here I stand, 



Desolation 'neath my roof: 

 They who owe a helping hand 



Calmly, coldly stand aloof. 

 Like the timid field-bird fleeing 

 When a tattered garment seeing, 



Craven-hearted friends will be 



At the sight of Poverty ! 



Friendship ! thou art like that flower 

 Sweet and fair to gaze upon, 



Opening at bright morning's hour- 

 Closing with the setting sun ; 



And thy heart (as /have felt it) 



Ice, that needs a sun to melt it. 

 Fair — but false — thou wert to me 

 Ere I tasted Poverty ! 



Love ! thou'rt like the hothouse plant 

 That in warmth can live alone; 

 From the hearth that knoweth scant 

 Love alas ! hath quickly flown. 

 Let it feel but wintry weather, 

 Soon is rent its faithless tether : — 

 Ah, fond heart ! I deemed for thee 

 Love a gem in Poverty ! 



False friend ! thou hast fickle proved, — 

 Still I mourn thee as a brother; 



Mistress ! whom I fondly loved, — 

 Like a lone distracted mother 



O'er her lifeless baby groaning, 



Thy dead love I'm weekly moaning. 

 God ! — that I should live to see 

 Such a curse in Poverty !
