THE NAVAL FORGES AND STEEL WORKS AT ST. CHAMOND. With the idyls and historic or picturesque subjects that the Universal Exposition gives us the occasion to publish, we thought we would make a happy contrast by selecting a subject of a different kind, by presenting to our readers Mr. Layraud's fine picture, which represents the gigantic power hammer used at the St. Chamond Forges and Steel Works in... more...

COCOS PYNAERTI. This is an acquisition to the dwarf growing palms, and a graceful table plant. It first appeared in the nurseries of M. Pynaert, Ghent, and is evidently a form of C. Weddelliana, having similar character, though, as shown by the accompanying illustration, it is quite distinct.

STEAM ENGINE VALVES. By THOMAS HAWLEY. In considering the slide valve in its simple form with or without lap, we find there are certain limitations to its use as a valve that would give the best results.

TURPENTINE AND ITS PRODUCTS. By Edward Davies, F.C.S., F.I.C. In treating this subject it is necessary to limit it within comparatively narrow bounds, for bodies of the turpentine class are exceedingly numerous and not well understood.
