In my despatch No. 12 I mentioned that M. Rivadavia had promised me some materials for the formation of a general report upon the state of this Government. I have lately received through him several notices thereupon, which have enabled me to draw up the paper which I have the honor to enclose, and which will be found to contain a general summary of the rise and progress of this State since the first declaration of its independence in 1810.
By the next packet I hope to be able to send you the report upon commercial matters to which I have alluded in the same despatch.
