hand, in each were found some incoherent and contradlrtory 

 conclusions ; as also propositions advanced without sufficient 

 proof; beside some errours, and obscure passages. But as 

 these imperfections were overbalanced by researches of great 

 merit, the academy, without accedinjj to every assertion of 

 the authors, have nevertheless thoun:ht it their duty, to di- 

 vide the prize between them, thinking them worthy of en- 

 couragement and honourable reward. 



On opening the two sealed notes. Doctor Henry Frede- 

 rick Link, professor of natural philosophy at the university 

 of Rostock, was found to be the author of No. 5 ; and Mr. 

 Placidus Heinrich, professor of natural philosophy and ma- 

 thematics at the Abbey of St. Emereau, at Ratisbon, the 

 author of No. 6. The notes of the remaining tracts were 

 burned, without being opened. 



Question on When the academy had made public the notice, in which 



the resistance , , i i • i 



of fluids. ^he marine department proposed a prize on the question 



concerning the resistance of fluids, they had engaged to 

 publish also the judgment, which that department, in con- 

 junction with the academy, should make on the memoirs 

 presented. Coniformably to this engagement, the academy 

 announce the receipt of three menioirs :— viz. No. 1. with 

 the motto: " 5if modus hsso maris ct viarum miiitiaeqtte.** 

 No. 2. ** Praesta vatura voce doceri, quam mgenio svo sa~ 

 "^ pere. No. 3. " England and France agree,' ^ The last of 

 these arrived after the term. 



Neither of them was found to satisfy all the conditions of 

 the problem : but, as the tract No. 2 exhibits a new theory; 

 which, though not established upon grouiids sufiiciently so- 

 lid, or applied to naval architecture in the manner the no- 

 tice required, is preferable, in some measure, to the theories 

 of Rome and don George Juan, agreeg-better with experi- 

 ments than the common theory, and deserves therefore to 

 be noticed advantageously ; the marine department, to re- 

 compense the author for his trouble and laudable efforts, 

 have decreed to him the prize of 1 00 Dutch ducats [£46 5s,], 

 and the academy have given their sanction to the decision. 

 The opening of the sealed note discovered the author to be 

 Mr. Zacbary Nordmark, professor of niathematics in the 

 university of Upsal.
