Hi Judy His certificate is on page 123, but have you also looked at pages 120, 121, 122 and 124? The first three pages document his earlier career (he went to sea at about 13 ie 1845 ish), the last is the other side of his certificate. Can't help with his later career but the lack of any further certificates suggest that he did not progress further (? lost at sea), or if he did, that he took his later examinations in one of the colonies and the paperwork stayed there.
