be judged of by the detailed example which the author gives of the 
method which he has followed, and which shows with what constancy 
he devoted himself to this disagreeable and troublesome labour. 
The author then passes to the examination of the charts which 
compose his atlas. Their whole number is 32; but, besides the 
grand divisions, they exhibit particular plans of different remarkable 
points: so that the number of articles of which an account is to be 
given amount to 143. In engraving these upon copper, the methods 
pointed out and practised by Fleurieu have been followed with im- 
provements upon them. 
The fourth book is entitled, General Results. It contains— 
tables, in which we find the diurnal longitude and latitude of the 
vessels ; the héight of the barometer and thermometer, and the 
degrees of the hygrometer, the direction and strength of the wind, 
the state of the sky, the declination of the magnetic needle, the 
lunar and solar points, and different observations; tables of the 
positions determined during the whole expedition; tables of the 
tides; and tables of the currents observed near the different coasts. 
With regard to the typography, it is sufficient to observe that the 
work comes from the press of the Imprimerie Royale. Nothing has 
been neglected to render the execution of the atlas worthy of the 
enterprise which it is destined to perpetuate. 
Travels of Ali Bey el Abbassi in Africa and Asia during the Years 
1803, 4, 5, 6, and 7, dedicated to the King. Three Volumes in 8v0- 
with an Atlas. 
«© Ali Bey el Abassi (whose work we announce, and of whom the 
portrait is at the beginning of the first volume) is known in Asia 
and Africa as the son of Othman Bey, prince of the Abbassides.* 
Eager to acquire knowledge, and possessed of the most happy dis- 
positions, he came when very young to study in Europe, where he 
acquired extensive information, which he afterwards applied to the 
practice of astronomy, geography, and natural history.” To these 
lines, which we copy from the preface, we will add from the 
verbal account of the contents of this work, which we heard given 
to the Class, that the editor, M. B., is known very advantageously by 
several memoirs relative to diiferent circumstances of the travels 
which he now publishes, and even by astronomical observations and 
geographical positions inserted in different volumes of the Connais- 
sances des Temps. As to the person of the traveller, we see in the 
preface that doubts have often been started respecting his origin. 
To these suspicions he opposes the marks of esteem which he re-~ 
ceived from the Emperor of Morocco, even after attempts had been 
made to blacken him in the estimation of that prince: the way in 
‘which he was received at Tripoli, at Cairo, by the scherif of Mecca, 
by the Pasha of Acre, and by other great personages: but without 
entering in the least into the discussion, with which we have no. 
concern, we shall merely point out briefly the principal new facts. 
* Our readers are of course aware that the name and character of Ali Bey 
were assumed by an Europeun,
