Discoveries made in Egypt. 253 
This is called Chifchaf, or Lesser Pettichaps; it is the Least 
Willow Wren of White and Bewick. 
Its length is four inches and a half, and it weighs two drachms. 
It is to be distinguished from the last species by its smaller size, 
by the under parts being lesstinged with yellowand the upper parts 
rather browner, by its legs being dusky instead of brown, and by 
its song. The eggs are white speckled with purplish red. 
The Chifchaf is frequent in gardens and orchards, particularly 
where larch and fir trees abound: it arrives in March and departs 
in November. This bird as well as the last may be easiest found 
in still rainy days, when they may be seen running nimbly about 
“the boughs and hedges. It is generally to be found flitting about 
the branches of the pine trees in pursuit of its prey, and where 
trees of this genus abound, we are rarely disappointed in finding 
it during summer. 
The head of this kind is somewhat more depressed than the 
last. 
I have given the above descriptions to prevent mistakes when 
the species are occasionally noticed in the journals of the weather, 
&c. as the times of the appearance of migratory birds are inter- 
esting appendages to calendars of the seasons.

XL. Discoveries made in Egypt by Mr. Cavicita; with Re- 
marks on the probable Reason for the principal Entrances into 
the Py yramids having been constructed descending in an Angle 
- of 26° or 27° to the Horizon. 
In our Number for February 1817 (see our fifty-first vol.) we 
announced that some important discoveries respecting the sphynx 
‘and the principal pyramid had been made by a Captain C. and 
Mr. Salt ; that by excavating round the sphynx they had ascer- 
tained that it is cut out of the solid rock ; that they had entered 
the chamber immediately over that containing the sarcophagus, 
and which had heen discovered by Mr. Davison in 1765, as de- 
scribed in his Journal published in Walpole’s Memoirs, the ex- 
istence of which had since been doubted; and that they found that 
the descending passage at the entrance of the pyramid, instead 
‘of terminating where there is an ascent to the two chambers, 
“continues in a straight line, till it joins the bottom of what has 
been hitherto called the well, but does not there terminate, but 
“proceeds onward to a well, or rather, as we now find, another 
‘chamber exactly under the apex of the pyramid, The Capt. C.
