. The issue of Guillemin's " Forces of Nature " in monthly parts being now complete, the publishers propose to follow it up by a 

 similar issue of the companion work on •' The Applications of Physical Forces. ' This important and valuable treatise, which gives in 

 popular lorm explanations of the various modes in which the "Forces" with which readers of the previous volume are now familiar may 

 be applied to human use, will now therefore be brought for the first time within the reach of a publie to whom in its original and costly 

 form it was inaccessible. The mere mention of a few of the subjects dealt with in the work is enough to show its eminent fitness to 

 supply the ever-increasing thirst for scientific information : e.g. The Pendulum, the Balance, Hydraulic Press, Artesian Wells, Pumps 

 /■I • tngmes. Air Pumps and Guns, Balloons, the Stethoscope, Bells, Drums. Stringed Instruments , Wind Instruments, the Organ, Mirrors, 

 Ligntnouses, the Microscope, the Telescope, the Stereoscope. Photography, Heliography, Heating Apparatus, the Steam Engine, Steam 

 /Navigation, the Locomotive, the Compass, Lightning Conductors, Electric Telegraphy, and other applications of Electricity

nc inhabitants of Europe are now exciting an inti linds of thoughtful men which, twenty years ago would 



nave seem ind which can no longer be ig ,1 Man in Great Britain is rapidly being 



unfolded, principally by the careful and scientific exploration of mains which arc eloquent of the condition of things that 



re the art of letters was known in the North ; a en instrumental in bringing tins about 



veil will ever deserve a foremost place. . . . In conclusion t remains merely to say that this valuable work fills a void in 



logical record of Great Britain, and that it contains a larger m book hitherto pub- 

 lished relating to the Bronze age in this country. ' — \V. BOYD DAWRINS.
