84 REPORT—1843. 
from any accordance subsisting between the Cape and Bathurst, a tendency 
to contrary movement is apparent, as will become evident by the comparison 
of the changes in twenty-four corresponding hours at Feldhausen and Bathurst 
as follows :—

These are all the terms in which there are corresponding observations, and 
among them, three-fourths in number and all the most considerable in respect 
of range, are cases of contrary movement. The fact is certainly remarkable, 
and though it does not appear easy to refer it to any obvious cause, it seems 
well worthy of further inquiry. 
At Bathurst the diurnal oscillations are not well made out, which is no fault 
of the observations or the observer, Mr. Morgan, whose care and assiduity in 
the making and registering of meteorological observations are quite remark- 
able and deserving every encomium. The contrary is the case at the Cape, 
as the following comparison will show :-—

American Group. 
The United States and Canada have furnished us with thirteen term-series 
up to the end of 1838, observed more or less connectedly at eighteen stations, 
* In this case the observatory has been compared, and there are, strictly speaking, only 
twenty-two hours in each series which correspond,
