I have created a PBB resource of James Denney’s Studies in Theology. You can download it by clicking the attachment link below.
According to Denney’s bio on Wikipedia, these lectures delivered at Chicago Theological Seminary in 1893 first brought attention to his views on the atonement. Later he would publish his best-known book, The Death of Christ, on the same subject. You can also get this work in PBB format here.
