Mr. Allen, who owned the chief of the property about Fullerton, the village in Wiltshire where the Morlands lived, was ordered to Bath for the benefit of a gouty constitution — and his lady, a good–humoured woman, fond of Miss Morland, and probably aware that if adventures will not befall a young lady in her own village, she must seek them abroad, invited her to go with them.

A guinea was a gold coin with a value of 21 shillings. (The name came from the Guinea region in Africa, where much of the gold used to make the coins originated). Before 1971, a pound was equal to 20 shillings, so 21 shillings would be 1 pound and 1 shilling; 10 guineas would be then 10 pounds and 10 shillings (or 10 pounds and half)
