derneath and the rod rests upon it from above. These two lamps are intermedi- 

 ate between the arc and incandescent kinds. In the Joel a carbon point from 

 below bears against a copper disc above. The Soleil is like the Joel, except that 

 the point of contact between the carbon point and the copper disc is surrounded 

 by chalk or lime which is rendered incandescent. In the Jamin, which is a 

 simphfied form of the well-known Jablochkoff candle, the strip of glass or plaster, 

 which, in the latter, separates the two carbons standing side by side, is discarded, 

 and the carbons stand with only air between them. The Swan Hght, which is of 

 the incandescent class, has been used for the meetings of the Congress in the 

 Salle des Seances and in the auditorium of the Opera-House, on a gala perform- 

 ance, given in honor of the Congress. — Iron Age. 



ARTS AND SCIENCE OF ANCIENT ROME. 



HORATIUS FLACCUS, 30 B. C. 



Msecenas, noble son of royal line 



Protector mine, effulgent patron, friend : 



(In aims and tastes diversely we incline 



As ever 'twas and will be to the end.) 



Some love the Olympic dust to raise. 



The goal with glowing chariot-wheels to graze. 



And so the victor's palm, illustrious, prize 



That haughty gods from terrene men they rise. 



This one exults when changeful Romans praise 



And three-fold honors 'round him strive to raise ; 



Another, when the grain from Libyan floors 



Is swept and locked within his granary doors : 



A third th' ancestral fields prefers to till — 



Attalic wealth could ne'er on him prevail 



To cleave the Myrtoan wave with Cyprian keel. 



The merchant, prospering, dreads ^gea's wind-tossed seas 



And, boastful, lauds his city's tranquil ease ; 



But soon, unwiUing yet stern want to face, 



His disused ships refits for ventures fresh. 



This one nor cups of ancient Massic wines, 



Nor wasteful hours from busy day, declines, 



Now stretched supine beneath th' arbutus' shade, 



Now, near the sacred murmuring*., fountain head. 



The camp, with fife and trumpets' mingled sound 



Delights; e'en war, so feared by mothers' fond. 



The hunter, heedless of his spouse's tender care, 



Delays, unmindful of the freezing air.
