It is difficult to contemplate a catalogue of this kind without being 
impressed with the important aid which Geology and Comparative 
Anatomy have afforded to each other. To those who in years past 
were struck with the discoveries of the great author of the ‘Ossemens 
Fossiles,’ and have traced the addition after addition since made to 
our knowledge of the forms of vertebrate animals which have existed 
prior to our day ; delighting alike in contemplating the linking toge- 
ther of these forms by fresh researches, and the history they afford 
us of the additions to, and changes in terrestrial animal life effected 
upon the earth’s surface in such comparatively recent geological times, 
these labours of our colleague cannot but afford the highest interest. 
Let us hope that the researches of geologists may present him with 
an abundance of materials for thought and description, and that the 
meetings of this Society may continue to be enriched by his commu- 
’ nications. 
We have next in the order of papers to refer to a communication 
from Mr. Richard Brown, in which he considers that he has discovered 
evidence, in the paleozoic coal-field of the island of Cape Breton, of 
the connection of Stigmaria-form roots with a stem of Lepidodendron. 
An interesting figure accompanies his description of a fossil plant, 
supposed to belong to the Lepidodendra, found above the Sydney
