The above image is from an 1835 Scottish school exercise book belonging to John Miller. This was his final year in school, which he completed at age 17.
John Miller was educated in the best school system in the world at that time. About 1700, Scotland organized the first national education system since ancient times, which resulted in the highest literacy rate in the English-speaking world, and was a factor in the extraordinary contributions made by Scottish intellectuals to the world in the 18th century (the Scottish Enlightenment).
The exercise book shows that he studied subjects including history, literature, mathematics, religion, and classics (Latin). It is said that mathematics was his best subject, and when he emigrated to Canada, he planned to be a surveyor.
The quality of penmanship is the same throughout the entire exercise book. In that era, unless you owned a printing press, all documents were handwritten. Clearly poor handwriting, particularly for commercial documents, was intolerable.
