NOTICE. 



Many of our subscribers having urged the formation of a Microscopical section in 

 connection with the British Naturalist, we have decided to arrange this, and also 

 in connection therewith for a circulating slide cabinet. This section will be sub- 

 divided into decades or circuits of ten persons, and will, it is hoped, be the means of 

 giving a greater impetus to microscopical investigation in the various branches 

 of Natural History. A note book accompanies each cabinet. Those interested and 

 desirous of participating will be good enough to send their names to the Editors' 

 British N'aturalist.
