Hi Ingrid,
Unfortunately, I cannot access an image of Augustin's baptism record as I do not have a subscription to Ancestry's Drouin collection, as it was after 1909, where most of the microfilm images stop. Perhaps someone at the Acadian-French-Canadian Mailing list can help if you subscribe to it. Link is as follows.

Augustin was baptized in Bassin on the date you indicated.
Best regards, Dennis
These images you could have accessed via the Mormons website: www. familysearch.org
