Аннотация:The first objective of this dissertation is to prepare both the fac-similar and the semi diplomatic editions of minutes of the municipal council of Botucatu, São Paulo State, which date back to 1858 and 1859.As the philological labor is a multidisciplinary activity, we also propose to raise some codicological and paleographic aspects of the book in which these minutes lie.W hile reading these documents, we noticed that the different writings of the graphemes and , especially in intervocalic position, might, at times, cause difficulties in reading to researchers preoccupied with historic linguistics issues, because the variation, both in writing and use of these letters, is wide.Besides this, there is also variation in the use of the graphemes and in representing different phonemes.Based on the finding that and present variation both in shape and the phoneme they represent, our second objective is to examine, in our corpus, occurrences of and allographs that raise greater paleography difficulties and verify the variation in the use of the graphemes and only in intervocalic position.
