At the last anniversary meeting of the Royal Bavarian Aca- 

 demy of Sciences at Munich, M. Bader read a Discourse on 

 the Possibility of determining the Principles of Eth'cs by Re- 

 ference to the Physical Sciences. M. de Scbrank read an 

 ingenious Dissertation on the Influence of mental and bodily 

 Temperament in furthering the Progress of the Sciences, and on 

 scientific Occupations. IVI. Schlichtgerol, Secretary General to 

 the Academy, recapitulated the proceedings of last year. The 

 library, he observed, had been greatly augmented ; the botanical 

 garden enlarged, and enriched with many new plants; and a do- 

 nation had been made of the literary collections of the late Pro- 

 fessor Schraiber of Erlangen. 



The Philological and Philosophical Class of the above Acade- 

 my proposes for the year IS 15 the following as the subject of a 

 prize question : ''As the writings and doctrine of Plato have 

 been hitherto the subject of numerous jihilological and philoso- 

 phical inquiries, and their success depends in an especial man- 

 ner on a correct knowledge of the authenticity and chronological 

 order of the writings of this philosopher, the Academy wislies 

 that the learned should turn tlieir attention to these subjects." 

 In consequence, all men of letters who are acquainted with the 

 works of Plato are invited to state what treatises in his name 

 are of doubtful authenticity, and in what order those are to be 

 taken which are avowedly authentic. Memoirs on this subject 

 must be transmitted on or before the 20th of March 1815. 

 The prize is 50 ducats, and the successful work is to become 

 the property of the Academy. 



M. Schoen, Professor of Mathematics in the University of 

 Wurtzburg, has recently published at Nuremberg a mathema- 

 tical work entitled " A Complete Tiieory of Astronomy, with 

 a Supplement concerning the Calendar; preceded by the 

 Theory of Conic Sections and some Curves of the higher Orders; 

 with four tables and eight engravings." In this work M. Schoen
