April 18. — M. Majendie, in the name of a Committee, read a 

 report on M. Dupont's collections of Animals and Anatomical 

 Preparations. The Committee observe, '' We have expressed to 

 M. Dupont our satisfaction at the manner in which he has pre- 

 pared and stuffed the Birds, and preserved the Papiliones; but it 

 is not to this kind of merit that we would call the attention of 

 the Academy. M. Dupont has for several years devoted himself, 

 and with indisputable success, to the art of modelling in wax. 

 The articles which have been submitted to us have all the per- 

 fection to which this art can be carried. In some respects in- 

 deed, such as those of the truth of the colours and transparency 

 of the organs, M. Duponthas surpassed his predecessors. Your 

 Committee are then of opinion that this young naturalist is en- 

 dowed with the talents necessary for practising with the greatest 

 success the art of modelling in wax, that he merits the commen- 

 dation of the Academy, and that it is desirable to encourage so 

 useful an art."
