On the ScvenlhSection of Vessel's Astronomical Observations. 34 1 



analyses of works of science or the useful arts ; written, many 

 of them, as my inquiries have in several instances enabled me 

 to ascertain, by eminent Professors and known scientific cha- 

 racters: but of late years, since the overwhelming flood of novels 

 and works of fiction on the fields of literature, of travels 

 and voyages, and wordy disquisitions on political economy, 

 and a few other subjects devoid of fixed principles; these 

 have enabled the Reviews alluded to, to fill dieir periodical 

 Numbers without calling in the aid of any scientific or prac- 

 tical men, and science and the useful arts have accordingly 

 been almost entirely banished from their pages ; volume alter 

 volume of these Reviews having appeared, without the notice 

 of a single work of this kind ; except, perhaps, that its title 

 may have appeared in their monthly or quarterly list of new 

 publications. 



This state of things, so degrading and injurious to science and 

 art, I saw no hopes of being removed, until the announcement 

 of the Monthly Critical Gazette ; which, although its notices must 

 often be too short to answer fully the purposes desired, yet, 

 if candidly and fairly done, as I understand to be the wish 

 and determination of the Editor and Proprietors that they 

 shall be, these notices cannot fail of being useful ; and parti- 

 cularly, as I hope, in stimulating the other Reviews, having 

 more ample space, to return to and even improve upon the 

 good practices, from which they have departed, of giving full, 

 able and early accounts of important works of science and 

 research. I am, gentlemen, yours, &c.

 A getlier all the reductions which, agreeably to the investi- 

 gations here communicated, are to be applied to the Kbnigs- 

 burg observations with Rcichenbach's circle, and by which the 

 calculations are made in the journals since the beginning of 

 1822. To the readings of die circle for an observation made 

 in the meridian, or reduced to the meridian, is added for flexure
