in the Britannia Romana , where they make Part of 
the Word INSTIT\£R/NT for INSTITVE* 
x RVNT (a). How frequent and various fuch Com- 
binations were, efpecially under the lower Empire, 
appears by the Table of them publifhed in that 
Work (]?). Some of which feem to have been the 
Effect of Fancy in the Workmen, and others occa- 
ftoned thro Want of Room, as in the prefent Cafe, 
As to the Meaning of the Word ALATORVM, I 
fuppofe it to be an Adjective, the Subftantive CAS- 
TRORViM being underftood ; and that the fame 
Place is intended, which Ptolemy calls nregarov 
‘Tgci]o7reS'ov (e), and modern Geographers generally take 
for Edinburgh. For as Ptolemy was himfelf a 
Stranger to that Country, his Greek Name was pro- 
bably an Interpretation of the Latin , Cajlra Alata j 
which Mr. Horfley thinks might be fo called from 
the Situation of the Place fomewhat refembling a 
Wing (d). But as there is good Reafon to think, 
that this Infcription was writen long after the Time 
of Ptolemy (as will be fhewn afterwards) the Word 
CASTRA might then have been dropr, and the 
common Appellation of the Place be only ALATA. 
There are other Examples of the like kind, which 
may render this very probable. For we meet with 
a Roman Station in the County of Ejjex , which 
both in Antonines Itinerary of Britain (e) and Peu- 
linger s Tables is called AD ANSAM, from the 
angular Turn of the Road there, as it is laid down 
in
