Several short communications have also been made, and 

 will be found recorded in the Proceedings. Some of these 

 are notices or descriptions of objects brought for exhibition. 

 Such communications are frequently of much interest ; and 

 the practice of giving short accounts of objects, to be fol- 

 lowed by the examination of the specimens, is a very bene- 

 ficial one.
