ture and properties of the subjects treated. The system of ar- 
rangement the author has adopted is founded .on electrical af- 
fections, and is consequently well calculated to facilitate the 
study of electro-chemical science. The work in this point of 
view is particularly deserving the attention of the chemical stu- 
dent, and is altogether a production which does much credit to 
the well-known ingenuity and research of its indefatigable au- 
thor. 
Memoirs of the Life and /Vritings of BENJAMIN FRANKiIN, 
LL.D. F.R.S. Gc. Written by himself to a late Period, 
and continued to the Time of his Death by his Grandson 
Wiiwiam TemMPLe Frankuin. Vol. III. 4to. pp. 570. 1818. 
The present volume, which is the last of a very valuable and 
important work, comprehends the select political, philosophical 
aud miscellaneous writings of Franklin. Some of the essays 
contained in the philosophical branch have already appeared ; 
but by far the greater portion of it, including several of the latest 
and most ingenious of the Doctor’s writings, are stated to be 
now for the first time printed from his own manuscripts. 
Mr. W. Westall, who accompanied Captain Flinders on his 
voyage round the world, has lately executed a work, consisting 
of a variety of Views of the Caves in the North-west Riding of 
Yorkshire, with some of the most interesting scenes in their 
neighbourhood, particularly Malham Cove and Gordale Scar. - 
They are not only highly picturesque, but appear to be geo- 
logieally correct representations of some of the most extraor- 
dinary scenes in .this country; and it is a strange circumstaace, 
that no work upon the same subject has before appeared, as the 
caves have for some years past attracted a great many visitors. 
An Essay, which Dr. Jos. de Matthe is readin the Archeo- 
logical Society at Rome, on the 29th of Feb. 1818, has now 
been published under the title of Sull’ origine de numeri Romani. 
The author attempts to prove that the Roman numerals, as well 
as the ancient Etruscan, originated in the nails which these na- 
tions, in the earlier periods of their history, caused to have an- 
nually fixed by their magistrates, for other than chronological 
purposes, in the Temple of Jupiter, and in that of Nurtia, their 
Goddess of Fortune, at Vulsinium (Bolsena).
