In all this there is no hint or attempt at any distinction, as to the claims to be presented, between those which are perfect and those which are imperfect in their character. On the contrary, the language of the eighth section is as precise and comprehensive as it could well be made, in that it includes every person claiming lands in California “ by virtue of any right or title derived from the Spanish or Mexican government.”
