I love thee, Mary, and thou lovest me. Our mutual flame is like the a5nity That doth exist between two simple bodies. I am Potassium t o thine Oxygen. 'Tis little that the holy marriage vow Shall shortly make us one. That unity Is. after all, but metaphysical. 0 , would that I, my Mary, were an acid, A living acid; thou an alkali Endow'd with human sense, that, brought together, We both might coalesce into one salt, One homogeneous crystal. Oh! that thou Wert Carbon, and myself were Hydrogen; We would unite to form 0kIiant gas , to Or common coal. or =phtha-WouId Heaven That I were Phosphorus and thou were Lime! And we of Lime composed a Phosphnret. I'd be content t o be Sulfuric Acid, So that thou mightst be Soda. I n that case
We should be Glauber's salt. Wert thou Magnesia Instead, we'd form the salt that's named from Epsom. Could'st thou Potassa be, I Aqua-fortis, Our happy union should that compound form Nitrate of Potash-otherwise Saltpetre. And thus, our several natures sweetly blent, We'd live and love together, until death Should decompose the fleshly "Tertium quid," Leaving our souls to all eternity Amalgamated. Sweet, thy name is Briggs b n d mine is Johnson. Wherefore should not we Ag, to fam a ~~h~~~~~~~ f, ~ ~ We will. The day, the happy day, is nigh,
When Johnson shall with beauteous Briggs combine. London Punch,

Precious alloys should find wider applications. AUoys of precious metals should prove useful in other fields than dentistry, the American Society for Steel Treating Meeting recently in Boston was told by Prof. R. C. Brnmlield, of Cooper Union, New York City. Gold, silver, platinum, palladium, and other rare elements, when alloyed with the baser metals have service qualities that can be known only by actual experimentation. according t o Prof. Brnmfield. It is estimated that eight million combinations are passible, each with its unique characteristics. Only a few of them have ever been developed, and these have been used in dentistry. The resistance of these alloys t o discoloration and their possibilities for heat treatment recommend their use elsewhere, Prof. Brnmfield said. The ultimate strength of some of these metals is as much as 90 tons per square inch. The strength of steel ranges from 50 t o 100 tons per square inch.--Science S~M~CC
