which we had been looking out for full three weeks before 
we saw it on the 26th of March. 
The following parallel columns of dates are intended to 
show the difference in the time of arrival between Egypt and 
England, but they are not the same individual birds which 
pass from the one country to the other, at least we may 
fairly surmise that they are not. The dates for Egypt are 
from my notebook, those for England being the mean of 
twelve years’ observations of earliest arrivals made by my 
father, or abstracted by him from the various periodicals.

I will now draw a further comparison between Egypt 
and Algeria, and it may be as well to remember that 
Algeria is upwards of 600 miles, or more than ten degrees 
further north than the tropic of Cancer, which bounds Egypt 
to the south ; yet there is very little difference in the time 
of the arrival of its migrants. 
EGYPT. ALGERIA.
