I've zoomed in and though it’s a bit blurr4ed, I can see that for example for Charles Chapman ( my husband's ancestor) the cutting says Chapman, Charles Lincolnshire (his place of birth) 1821 (his year of birth)
Next line – C (for captain), 8485 (his masters certificate number), Liverpool (where he got his certificate) and the year he got it in, 1853.
Subsequent lines are all the ships & voyages Charles Chapman undertook prior to 1869, which is the first year in this masters register. So the entries go ships name (Great Britain), her tonnage (20-odd thousand tons), the date he was on her in command, and then where she went (e.g. US, Australia, West Indies etc).
