 hibited, 29th May 1839. Printed in the Society's Transac-

The Society desired it to be understood, that all the Models 

 to be furnished for their Museum, for which the above sums have 

 been set apart, should be made to a Scale, and to the satisfaction 

 of the Curator of the Museum. 



The President having delivered the premiums to the suc- 

 cessful candidates, accompanied by a suitable address, concluded 

 with observing, *' That many fair testimonies had been afford- 

 ed of the progress of ingenuity, invention, and improvement 

 of the Useful Arts, by the claims on the Society's patronage 

 for the preceding season. Numerous valuable and interesting 

 communications had been also made, models and drawings ex- 

 hibited, though not in competition. It appeared, likewise, that 

 the natives of Scotland were by no means of inferior genius, 

 as might be well expected, to those of other countries ; their 

 education being excellent, their ardour and perseverance in- 

 surmountable, invested them with qualities which could not 

 but lead to distinction and success."" 



The Models, Drawings, &c., of Inventions, &c. (Session 1838-
