This section of the Society has made very considerable 
- advance during the past year, not only in the number of new 
members, but also in the character of its teaching. While the

coming summer. These should be invaluable, inasmuch as they 
will be associated and connected, inter alia, with meetings of the 
same nature of members of other societies, and will show the 
“ budding naturalist ’’ how to work and observe in the field. Due 
notice of these meetings will be given. The following meetings 
were held during the past session :—

purposes, the rock is really fissile sandstone. It contains many 
fossils, both of animal and plant remains, and the earliest butterfly 
is found there. It is, too, especially noted for the discovery in 
it of the first mammalian remains in 1764, though since then other
