j4 Manual of Analytical Mineralogy, intended to facilitate 

 the practical yinalysis of Minerals. By Frederick 

 Accu&J, Honorary Member of the Royal Irish Academy, 

 Operative Chemist, Lecturer on Experimental Chemistry 

 and on Mineralogy and Pharmacy. Second Edition, two 

 Volumes, ISmo. 



When we announced last month, that Mr. Accum had 

 in the press A System of Mineralogy and Mineralogical 

 Chemistry, we had no expectation of being so soon gratified 

 with another production oF this able and zealous labourer in 

 the field of chemical science. It is not a long time since 

 we announced the first edition of this work, and expressed 

 our hopes that a second would soon be called for. Our 

 wishes have been more than gratified. The present work, 

 thouoh presented to the public as a republication, is in many 

 respects new, the additions that have been made being very 

 numerous and highly interesting. All the modern improve- 

 ments in analysis are detailed with brevity; but at the same 

 time with so much perspicuity, that the student in this 

 amusing science can be at no loss to apply them with effect. 

 This vfork, though modestly entitled A Manual, will be 

 found worthy of the notice of all who cultivate chemistry, 

 whatever their acquirements may have been.

July 1.— Mr. Davy, in the Bakerian Lecture on the de- 

 composition of the alkalies, read in November IS07 before 

 tlie Royal Society, de^ciibed some experiments on barytes 

 and strontites ; from which he inferred that these bodies 

 contained inflammable matter. In a communication made 

 this evening, he states that he has since made a number of 

 experiments with a Voltaic battery of 36.000 square inches, 

 on these and the other alkaline earths, and silex and alu- 

 mine. All these bodies, when slightly moistened, and 

 acted upon by iron wires, negatively electrified, undergo 

 change at the points of contact. And the metals of the 



earths
