"The _Arcana of Art and Science_ is the fourth volume of a little work of the most useful and entertaining description. It is brimful of all the new facts that have shown themselves above ground in the course of the year. Every page is a volume, and many contain the results of whole years of ingenious labour and experiment. Every description of discovery, invention, experiment, receipt, observation, or memorandum of a remarkable occurrence in nature or art during the year, is here recorded, briefly, but clearly.--It, in fact, is the very essence or extract of the scientific pursuits of the whole world for one year. All this is to be had for five shillings. We recommend it to be laid in every place where a man may possibly lose five minutes for want of mental occupation."--Spectator, April 23. Printed for JOHN LIMBIRD, 143. Strand;--of whom may be had the Volumes for the three preceding years. * * * * * _Printed and Published by J. LIMBIRD, 143, Strand, (near Somerset House.)
