IN CANADIAN ROCKS. 105 



The substance, consequently, is an undoubted allanite : consisting 

 essentially of— SiO^, A?0^ Fe^'O^ CeO, CaO, MnO, (a trace,) and 

 a small amount of water. An exact analysis would probably reveaL 

 in addition, the presence of LaO and YO, with perhaps a half-per- 

 cent, of MgO, NaO, and KO. Part of the iron may also be in the 

 state of FeO.

* la 1857, Major Rains, at the instance of the late A. H. Armour, Esq., pre- 

 sented to the Canadian Institute a collection of silver and copper coins, consisting 

 principally of denarii, quinarii and assaria of the Roman Emperors, but com- 



t Coins of Chalcis, the capital of the district of Chalcidice in Syria are found, 

 but they are generally of the times subsequent to the Roman conquest, and bear 

 the names (in Greek characters) of Roman Emperors. Chalcis in Euboea took 

 its name from the x^A/ceo fieraWa (copper mines) in its neighborhood. 



t The weights of the coins are given and their denominations as thenco 

 derived, but the latter only conjecturally, the remark of Eckhel in his Chapter 

 de pondere ac valore monetae veteris, being borne in mind. " Fatendum est 

 multa esse adhuc in hac causa dubia atque incerta, multa Cimmeriis adhue 

 noctibus involuta, quod satis ex eruditorum litibus atque dissidiis apparet.'
