Dr. Carpenter found large areas of very low temperature in the 
temperate and inter-tropical zones co-existent with high-surface 
heat. The fauna of these cold areas in low latitudes corresponded 
precisely with that found in Sir E. Parry’s soundings from Arctic Seas. 
When the bottom temperature was high the fauna changed its cha- 
racter, the Cretaceous formation going on in warm localities, while in 
close proximity the greensand is accumulating under privation of heat. 
With the increase of our knowledge of the forms of life satisfactory 
theories respecting its means of sustenance have been offered; the 
lowest forms—mere atoms of living jelly—absorbing nourishment from 
the universally-diffused remains of surface life, and in their turn 
feeding higher organisms. 
Carpenter found in the gases separated from deep water a constant 
increase in the quantity of carbonic acid where life abounded, and a 
corresponding decrease where it was scanty. 
In the ocean, as on the land, food and oxygen—excretion and 
carbonic acid, are the conditions and consequences of life. 
Mr. Hennah concluded by saying that it is impossible to overrate 
the importance of the discoveries recently made by Carpenter and 
others, and that he hoped the discussion would turn on them. 
In the course of his report he mentioned the common Difflugia of 
our heath springs and streams as a convenient example of Arenaceous 
Foraminifera for examination in a living state.

several interesting reports of other Societies, though in type, are com-
