Ye lhaveseenaletterfrons Mrlexico,received by the l.7lorowi.e,written by art iudividual who evidently has access to the views of tdie existing Gover tnment, a' Well as thiose of nmost of the leading mcn of the Country, ared lwIirib is cusious as affording some insigbt into the real State of paaste there, as well as of the actual support Iturbide may earpect to receive on his landing in Al\exico. It is, in fact, addressed to Iturbide himself, under the Imnprtssion that he still remained in England, waiting for tho favourable moment to peoceed on his expe- dition. To jutige from the tone of the communication, the writer appears less a partisan of the ex-EmperoT, than one actuated by the desireof rescuirgl is country from a state w hicil he considers im- Possible to be a permanent one. Ile admits, however, that 'Mr. L7arvey, whon be considers in a state of actual in- faetuation with regard to those who are at tile head of at: airs, has constantly urged to Alr. Canning, in. his recent communications, the necessity of -supporting those who have thereins of Government in their hiands. In this point, too, he is sirpportetl by the other Commissioner. The officers ot tile Vaeoros?, who vi. sited the capital, have formed, he says it ontrTary wopinion, and are PreOared to reqort the persons in po7eer as wholl) incapable of acquir- irng tel confidence of the difterti lr provinces,so as to uni te them under one formn of governmenl. lIt is obvious. however, that the Caon is- atoners mus: ha'v' had mutch better opportunities for fonninga jun;g- neat, than cA;d possibl5' have occurred to naval officers during so short a -^cay, and vhcsc niinds also mnight be in a Mtate Df irritation frort the insrecure state of the country, and the dangers to which they WrcMexpOsed on theirjourney froma the capital. Thewsriterof the letter Ott which wve are remarking appears,on the other hand,to have the *tstM decrded -onviction that neither the esisting Government nior ally other can hlavcinflnence enough tounite the iIexican provir.ees into a fetiera- eon, with any chanes of nermanence, as hICe s thal a form of' i;overnment for dd hich the pt'ejudices andtnbits of the people render them wholly u:.i:- Hie therefore comes to the coeiicusion thlat Itur- bide is the only man whoiii all. keersons, not actually coniected with the Government, would be 'willig to see placed at the head of the state, and that there reinains, theretoie, no seTious obstacle to his Success. In Stpport of this opinion, to q uote his own word3, lhe atdds, " So firmly am I pTersuaded of this, that were you to land to.rMorrow in Mexico, etteii(led by only one servasit, you would certainly in less than a week be at ile heLar of 10,080 men-; We collect nothintr from tthis letter which may assist in d terminiinng whether lturbitde is actuated by privateamrbitioll, or whethar lie is the instrunient of tthe Holy Alliance, in enideavouring to rgain the thTrone of Alexiro.
