cIentlemen, 



In the year 1823 the Royal Academy of Sciences proposed, 



as the subject of their prize essay, an inquiry into the nature of 



the digestive process in the different classes of animals. Of the 



Ticandiaates that offered themselves no one was deemed to have 



entirely satisfied the views of the Academy, though two of them 



j^ere considered worthy of honourable mention, " The authors 



^{says the report) have made a great number of experiments, and 



"nave obtained remarkable results. For this reason, arid in con- 



' sideration of the expensive nature of the researches in which 



they engaged, the Academy have adjudged to each the sum of 



1500 francs." The authors of one of the essays were MM. 



Leuret and Lassaigne, who, I presume, accepted the offer of the 



Academy; of the other. Professors Tiedeman and Gmelin, of 



Heidelburgh. The latter gentlemen seem to have been offended 



with the decision of the Academy, refused the above offer, and 



published their essay themselves.f That of Leuret and Lassaigne 



has been also published ; J and the object of the present com- 



jpunication is to make some remarks on certain passages in 



these works, in which I am myself more immediately concerned ; 



and first of MM. Leuret and Lassaigne. 



In page 114 of their work, these gentlemen refer to my paper 

 pubhshed in the Transactions of the Royal Society, on the free 



"* "Ef ad not die salts got damp in the course of the seven months ? — Ed.
