Next follow in order the " Experimental Researches in Electri- 

 city," from the First to the Fourteenth Series, illustrated by the 

 original engravings, from the Philosophical Transactions. 



The volume concludes with a copious and minutely particular 

 index, occupying eighteen pages, and presenting, in fact, a complete 

 analysis of the objects and results of the author's "Researches" 

 contained in this Avork. This we are enabled to say from our own 

 acquaintance with those " Researches," and examination of the in- 

 dex ; which has also the recommendation of having been, as we 

 happen to know, constructed by the author himself, a recommenda- 

 tion Avhich every one having any practical experience in the bibUo- 

 graphy and history of science and scientific discovery will know how 

 to estimate. 



As the Fifteenth Series of Mr. Faraday's Researches has already 

 been read before the Royal Society, and will appear in the forth- 

 coming part of the Philosophical Transactions, it is evident that his 

 devotion to the subject is still unremitting, and we earnestly wish 

 him health and happiness yet further to develope the laws of elec- 

 ti-ical action, hoping to have the pleasure of announcing to our 

 readers, in due time, the publication of another and similar collection 

 of his " Experimental Researches in Electricity," in sequence to the 

 present volume.

SCIENTIFIC MEMOIRS, PAIIT V. 



PART V. of the Scientific Memoirs, being the first of the second 

 volume, is just ready for publication. It commences with a paper 

 by Jacobi on some Electro-Magnetic Experiments, forming a sequel to 

 the Memoir on the Application of Electro-Magnetism to the Move- 

 ment of Machines, of which a translation appeared in the first vo- 

 lume. The second article is one the importance of which M'ill be 

 readily appreciated at the present time ; it is a translation, revised by 

 Professor Lloyd and Major Sabine, of the " Results of the Observa- 

 tions made by the Magnetic Association in the year 1S3G," edited
