 sisting of a circular metal plate with a rim, containing several 

 layers of flannel, kept well moistened, covered with a glass shade, 

 under which is a zinc frame with trays for the brass or glass 

 animalculse troughs or slips. With this apparatus the objects to 

 be studied can be watched day by day for weeks, the daily 

 changes being easily noted. 



Mr. Stirrup exhibited zircons, garnets, and sapphires occur- 

 ring in the volcanic rocks of Le Puy, Haute Loire, France. 

 Those shown were found on Mont Mezen. They also occur 

 in volcanic rocks, near the Rhine, at Andernach. 



Mr. T. Rogers exhibited a number of fresh-water shells col-

 sinistral. They included three species of Melodomus from Zan-
