However, when I try comparing the two, this is clearly not Mrs Eaves. It's probably a Garamond, looking at the 'e' and 's', but my books don't show all the ligatures.

Looks kind of Caslon-ish to me, but I'm coming up empty handed.

Although it's not a match for the example above, Letraset's Eplica also sports 'il and 'it' ligatures in this style.
