contained 10 cohorts. The Ala Herculea seems to have been  
the Ala of a Legion, and consequently composed of several  
cohorts, and perhaps was the same as the Ala Gordiana, and  
may have changed its name under Maximian, of whom Victor  
says that he gave his new name to the troops. The Ala  
Gordiana also lay at Old Carlisle, as appears from  
inscriptions found there.
 "Legio VI. Victrix was in Britain when the Notitia was  
written, as were all these Alae. It is not improbable that  
the Ala I. Herculea, and the Ala Sabiniana, the one called  
from Maximianus Herculeus, the other from Adrian's wife  
Sabina, or Gordian's wife Sabinia, were the wings properly  
belonging to it.
 "When the Notitia was written, the Legio II. Aug. was  
withdrawn from Caerleon to Richborough, and its auxliaries  
probably garrisoned the east coast. The principal stress of  
defence about and before the time when the Romans quitted  
the island was ad lineam valli and the littus  
Saxonicum. I account for the want of inscriptions in  
these east and south stations, when they abound so much in  
the north, from the long residence and quiet of the Romans  
in the north. The Notitia gives the state of the Roman  
government and forces in Britain, not as they really were at 
the end of Theodosius II's reign A.D. 445, but 401 or 2,  
when the aforesaid legions were still in Britain, for it is  
evident they had been recalled before that time. When the  
Legio II. Aug. left us is not so plain, but I think we may  
fix the departure of the other to Stilico's drawing off all  
the forces of the empire to his aid, as described by  
Claudian:
 
 Venit ab extremis, &c.
 So that the Notitia seems to copy from an account taken at a 
time when the Romans had a flourishing civil power and a  
good army residing here, and not at the end of the reign of  
Theodosius II, when every thing was in confusion.
 "Both the commanders of legions and alae were styled  
Praefecti, and the latter was more profitable as well 
as more honourable, and sooner attained by successive  
rising. But the commander of the cohort is always styled  
Tribunus in the Notita, though sometimes in  
inscriptions Praefectus, a term of greater dignity,  
and a compliment to the officer. Cohors was properly  
a company of foot, Turma a troop of horse, and the  
commander of the latter a Decurio, and frequently  
Praefectus like the commander of a cohort. Vegetius,  
a late writer, who lived but a little before the Notitia,  
says the first cohort of a legion was styled  
Milliaria, and consisted of 1103 foot soldiers, and  
132 horse, and others had only 555 foot, and 66 horse. The  
commander of the first cohort was styled Tribunus,  
the others tribuni or praepositi, as the  
emperor pleased. I never met with a praepositus  
cohortis in any other book or inscription; perhaps it  
might be a modern distinction. However, in imitation of the  
first legionary cohort, the first auxiliary one might  
consist of above 1000 men, and the rest of more than 500  
(the 4th and 7th it is said were above 600), whence they are 
called Quingenaria, as the first was  
Milliaria, the rest by the note ∞ on this  
inscription, whose last words are to be read milliariae  
equitatae, not equestris or equitum, as in 
Pliny and other polite writers. Equitata is the camp  
term and used by Hyginus, who wrote expressly on that  
subject, and in the military style.
 "That this cohors I. Hisp. equitatae was sent by Adrian into 
Britain, appears from an inscription in Reinesius, Cl. 6  
cxxiix, and in Gudius."
 Sir J. Clerk's description of the Netherby bath in a letter  
to Mr. Gale, Sept. 23, 1734:
 "This edifice consists of two rooms, which, I believe, have  
always been under ground; for, at this time, there are marks 
of steps to go down to them. The door is finished by three  
large stones, one at top and two on the sides, each about  
six feet long, with marks of bolts and hinges. Each room is  
about nine or ten feet square, divided from each other by a  
thin partition of stone, and both under the same arched  
roof, which the workmen broke down. The outermost served for 
a little temple of Fortune, and in it the altar was found  
with heaps of heads of different animals, particularly oxen  
and sheep. The inner room was a bath, and, in my opinion,  
rather for bathing vessels to stand in than to be filled  
with water: for though there is a certain cement, composed  
of lime and beaten bricks, which covers both the floors and  
walls, and is indeed very hard; I have no notion it could  
ever hold water. The floors of both rooms are covered with  
large flat stones, and under them is an aqueduct or large  
empty space or canal, reaching from one end of the building  
to the other. These floors are covered with the cement about 
an inch and an half thick, which, I suppose, was because the 
stones were too cold to stand on. I believe it might be  
worth our while to imitate this cement in floors  
underground; for it seems the beaten brick, which is not  
very small, served to dry up the moisture of the lime and  
made it bind immediately.
 "The Spanish horse of the inscription could not be the  
northern exploratores, consequently this place could not be  
the Castra Exploratorum, as Mr. Horsley took it to be. I  
make no doubt but the true Castra Exploratorum was at  
Midleby and Burnswark hill in Scotland, 10 mils from  
Netherby; for there are three Roman camps to defend these  
grounds, and from the top of the hill a prospect of at least 
40 miles round, as I noticed to you once before, and as was  
likewise observed by Mr. Gordon. I believe if poor Mr.  
Horsley had lived to see this altar, he would have changed  
his opinion about the place. I don't know why it might not  
have been Luguvallium rather than Carlisle. If the etymology 
could be admitted to be Longa Vallis, it would exactly fit  
the country about Netherby, which is part of what we call  
Eskdale or Escae Vallis. I own the next station of the  
Itinerary would create some difficulty, but that would be  
only in the distances, about which we can have but little  
certainty.
 "From the heads of animals found in the Fanum Fortunae, we  
may guess the priest had picked them before they came there, 
otherwise the place had been a meer slaughter-house. The  
altar, no doubt, served for libations, or, according to the  
priest-craft of those times, for a small part of the  
viscera, while those holy men feasted on the rest  
themselves.
 "I observed on the pavement scattered about several  
fragments of fine earthen pots adorned with figures. These,  
no doubt, have served for oils, or paterae and prefericula.
 "About 30 ells in a strait line from this fabric is a  
spring, which, no doubt, you noticed. This has supplied the  
bath, and issued by the aqueduct. I shall only add, that  
Netherby is much the same kind of station as Midleby: for  
there are considerable vestiges of stone buildings in both.  
I believe
