This consisted of corrections of the first report, and a reswmé of the fresh 
sources of information which had accumulated since its date. The most 
important results of recent investigation were the geological evidence of 
a recent connection between the waters of the West Indies and the Pacific, 
and also of the comparatively recent elevation of many parts of the Rocky 
Mountains, and the probable connection of the North Pacific and North 
Atlantic during the Eocene and probably the Miocene periods, 
“On the Great Division of the Pacitic Ocean Fauna.’ By Mr W. 
Harper Prase.—The connection of the Hawaiian Islands with the 
northern part of Japan by a series of sunken islands, identical in fauna 
with the Hawaiian, and the non-existence of certain islands appearing on 
the charts between that group and the coast of America, were dwelt upon 
with reference to the peculiarities of the existing fauna.

*« Report on the Physiological Effects of the Bromide of Ammonium.”’ 
By Dr G, D. Giss.—The general conclusions may be stated as follow :— 
1. In small doses more or less long continued, bromide of ammonium acts 
as a tonic and absorbent, and exerts its peculiar properties upon the skin 
and mucous membrane. 2. It diminishes the weight of the body in poly- | 
sarcia, causing the absorption of fat, when combined with a regulated 
diet ; and this is effected with greater certainty than by any other known 
substance. 3. It improves the intellectual powers, increases the bodily 
capacity, and promotes healthy function. 4. Locally, it possesses a sooth- 
ing influence on the mucous membrane, and, according to the strength 
and mode of its application, so does it diminish sensibility. 5. In large 
frequently repeated doses, or given at intervals, it influences the entire 
mucous tract ; it affects all the special senses, and produces anesthesia 
or impaired sensibility of the various mucous outlets. 6. All the poison- 
ous effects are produced by very large doses, as from the bromide of 
potassium, but in smaller doses it is more certain and reliable, causes no
