•course of a day, and those at South Kensington, where sometimes several 

 hundreds of Board School children passed through the galleries on a 

 Bank holiday, bringing their luncheons with them and smearing the 

 glass cases with sticky fingers. The desirability of some kind of pro- 

 tection for a Microscope under those circumstances would be obvious. 



The thanks of the Society were given to Messrs. Watson & Sons for 

 sending these instruments for exhibition.
