Eamiorum Sagittariorum * (ooH- i- hamiorvm sagittar-) and 

 coTiors prima Batavorum (oOH. i. batavorvm). From the inscrip- 

 tions in which the first cohort of Hamians is named we derive the 

 dates A.D. 136-137, and about A.D. 163. On an altar (n. 295) we 

 find the date A.D. 258, and an inscription to Constantine as Csesar 

 gives the period 306-308. The cohors prima Hamiorum Sagittari- 

 orum was in the island in A.D. 124, as we learn from Hadrian's 

 diploma of this date. In the same record the first cohort of Dalma- 

 tians (of which there are memorials at Maryport) is named, and iu 

 both diplomas of Trajan — A.D. 104 and 106 — the fourth cohort of 

 Dalmatians is mentioned as being in those years in Britain. On the 

 first cohort of Batavians see § 7.

Tribunus Cokortis Primce JElice Dacorum Amhoglanna. NoTiTiA. 



This station is in Cumberland ; the preceding eleven are in North- 

 umberland. The eoJiors prima u^lia Dacorum is named in ^twenty- 

 two inscriptions found at Birdoswald. We have memorials here 



also of LEG- II- AVG-, LEG* VI" VIC* PIA' FIDELIS, VEXILLATIO LEG" 



VI- VIC-, and leg- xx- vv, and (in the neighbourhood) of the Ala 

 Petriana (al pet). From the inscriptions in which the first ^lian 

 Cohort of Dacians is named we derive the dates about JA.D. 212 



* In the Canadian Journal for April, 1869, I remarked : " As I have adverted 

 to the cohors Hamiorum, known only from British inscriptions, I may mention 

 that I have but little doubt that it was named in Hadrian's diploma of 124. 

 The letters are I- M- SALIN". I would supply HA as the missing letters. On 

 the meaning of SALIN I can offer no feasible conjecture, but it has occurred to 

 me that it may possibly be a misreading of SAGIT i. e. Sagittariorum." This 

 suggestion— 1- HAM- SAGIT- (which I regarded as uncertain, from doubt that 

 that any one could have read SAGIT as SALIN) — is now known to be nearly 

 correct, for Mr. Franks, on examination of the original plate in^ the British 

 Museum, independently ascertained that the true reading was — I' HAMIOR" 

 SAG ITT t. e. 7. Eamiorum Sagittariorum. (See L. S. p. 7.) 



f There also seems to be a trace of them in L. S. n. 382, where we find the 

 letters DECIBA that may be the beginning of the Dacian name — Decebahts. 



X In this inscription Modius Julius is named as Legatus Augusti Pro FrcBtore. 

 He is also mentioned in a " very roughly" cut inscription found at Netherby, 

 the date of which may be ascertained from the first two lines. Dr. Bruce (Rom. 

 Wall, Srd ed. p. 400) reads— 



IMP [ERATORI] [CAES. M. AVR.] (?) ANTONI [NO] 

 P. F. AVG. (?) BIS COS. VEXIL.
