"The Welchmans Hobby" is equally loaded with caricature, but the goat and cheese wheels soften the caricature. Noel Riley in her book "Gifts For Good Children" shows 6 patterns in this series, including "The Jews Hobby." The other patterns poke gentle fun at the sailor, the dandy, John Bull, the alderman, and the doctor. Perhaps "The Jews Hobby" was considered funny in the 19th century.
Another series of patterns, which were made to teach arithmetic to children in a humorous way, uses caricatures of Africans to portray the subject. "Subtraction," for example, shows a child stealing a wallet from a man. Both characters have exaggerated African features, and the act of stealing is a poor example of "subtraction." At least to me. Noel Riley shows six patterns in this series, including decimal, division, multiplication, improper fractions and division.
The last is a pattern with the words "Drink to me only with thine eyes & I will pledge with mine," which is an old English song. The lyrics are from Ben Jonson's "Song To Celia" (1615). The poem and song are lovely, but the exaggerated features of the African people on the plate are not. Is this appropriate humor? Or, an appropriate pattern for a child?
