OBSERVATIONS ON ALEXANDRIA. 
inclosed in beds of a mortar, harder than the bricks, which lead to a 
supposition that the royal baths were here constructed ; nor would 
it be easy to account in any other way for the smallness of many of 
the rooms, the dimensions of which can still be ascertained. No. 7 
marks the foundation of a round tower, and No. J 6 and 18 of two 
small square buildings, whose use it is impossible to conjecture. 
Beyond the Pharos, are very extensive ruins of buildings, to which, 
probably, Strabo alludes as being beyond the harbour, although 
they were connected with the palace. 
From the account above quoted, it is evident that the palace, with 
its numerous additions, and public buildings, must have covered 
a very large space of ground ; and I am inclined to believe, that it 
was only bounded on the south by the great street, and on the east 
by another, which I conceive to have extended from D to E on 
the west. I should hardly suppose it descended the high land con- 
nected with the promontory of Lochias. Strabo, who goes on gra- 
dually along the shore of the harbour, says, after having spoken of 
the palace of Antirrhodus, " Beyond this is a theatre, then the 
Posidium running out in a kind of elbow, from what is called the 
Emporium. Here is a temple of Neptune. Here also are seen the 
Csesarium, the Emporium, and the Apostases." The theatre may 
be considered as within the royal quarter, as may also the Posidium, 
which took its name from the Temple of Neptune, and which seems 
to be pointed out by the bend in the shore at No. i , as having been 
in that spot ; but if the Emporium were a public mart, as its name 
designates, it must be believed to have been beyond the bounds of 
the palace. 
That I am correct in the position I have given to the Posidium,
