This is George Whitefield’s book, Journal of a Voyage From Gibraltar to Georgia, which details his travels from Europe to America, and was published by Benjamin Franklin.   Franklin found Whitefield both interesting and sincere as a preacher.

Also notice the name that is written on the left page – “Catherine Loxley her Book”.  Back in the day, the possessive case was expressed that way instead of “Catherine Loxley’s Book”.  You also see that expression used on a lot of powder horns of this era, such as John Doe his horn. The apostrophe s we use today for the possessive is a contraction of “his”. So, now you know.
