THE ALUMNI JOURNAL, 



exceed one grain to the cubic foot and 

 the average output is 0.78 grain. Take 

 the question of hydrochloric acid, in early 

 times this was found to kill all the vege- 

 tation around the works. Then the 

 manufacturer ran water down the chim- 

 neys and into the streams, and he was 

 compelled to stop this. He said he would 

 have to close up his works, but he learn- 

 ed to convert the acid in chlorine and 

 make bleaching powder and he sends it 

 all over the world to bleach linen and 

 cotton, a positive source of revenue and 

 not waste. 



"Economy is wealth " is an old say- 

 ing. Wealth has its source in the appli- 

 cation of the mind to nature. Should 

 not then all men be rich ? Men are urged 

 by their ideas to acquire command over 

 nature ; cultivated labor drives out brute 

 labor. A good man of business knows 

 the adjustment of cause and effect ; for 

 every effort there is a perfect cause. 

 Good luck to him is tenacity of purpose. 

 Open the doors to talent and virtue, they 

 will do themselves justice and property 

 will not be in bad hands. 



Kvery man moving to this city with 

 purchasable skill in him gives every 

 other man's labor a new worth. The true 

 citizen merchant has but one rule, absorb 

 and invest, don't hoard. He must be a 

 capitalist. The scraps and filings must 

 be gathered together again and placed in 

 the crucible, the gas and smoke and dust 

 must be burned, and earnings must not 

 go to increase expense, but back to capi- 

 tal again. 



In this great city surrounded by the 

 triumphs of science and engineering, 

 you, whose rivers are ploughed by the 

 ocean greyhounds, you know well that 

 in the achievements of science there is 

 not only beauty but power. She has not 

 only revealed the wonders of the infinite 

 space with innumerable worlds, infinite 

 time peopled by unnumbered existences, 



infinite organisms hitherto invisible, but 

 she is an Archangel of Mercy devoting 

 herself to the service of man. Science 

 labors not to increase the power of des- 

 pots, but to extend human happiness, 

 economize human effort, extinguish 

 human pain. She has enlisted the sun- 

 beam to paint for us the faces of those 

 we love ; she has enabled us to talk and 

 hear the voices of those dear to us though 

 separated by miles of distance ; she has 

 given us the means to hush the sufferer 

 under the surgeon's knife, she points to 

 our railroads, steamships and telegraphs, 

 our electric lights, not as the results of 

 the degradation of mankind or the toil of 

 slaves, but as the rewards of pleasant 

 days and years studying her methods of 

 working and filling our hearts with the 

 pleasure of the acquisition of knowledge. 

 All is waste and worthless, till 

 Arrives the wise selecting will 

 And out of slime and chaos, wit 

 Draws the threads of fair and fit. 

 Then temples rose, and towns, and marts 

 The shop of toil, the hall of arts, 

 Then flew the sail across the seas 

 To feed the North from tropic trees ; 

 The storm wind wove, the torrent span 

 Where they were bid, the rivers ran ; 

 New slaves fulfilled the poet's dream, 

 Galvanic wire, strong shouldered steam. 



Relation between Depression of the Freezing 

 Point and Osmotic Pressure of Solutions. — C. 

 Dieterici. In answer to Arrhenius, the author 

 admits the greater accuracy of Juhlin's observa- 

 tions on the vapor pressure of ice and water at 

 temperatures below o° as compared with those 

 of Fischer, but still maintains that no strict pro- 

 portionality exists between the depression of 

 the freezing point and the osmotic pressure of 

 solutions. The theoretical relationship existing 

 between these two quantities is deduced, and it 

 is shown that the assumption hitherto made, 

 that the heat of dilution of dilute solutions is so 

 small that it may be neglected, is incorrect. — 

 Anier. Phys. Chetn., 1894, 263. 



Henialbumin is much recommended in cases 

 of chlorosis. It has an acid taste, is very solu- 

 ble in water, beer and wine, and contains all 

 the elements of blood, such ashaematin, baerno- 

 globliu. Iodosuccininiide is a substitue for 

 iodoform. Its name at once demonstrates its 

 composition.
