The Path of the Law(Culver, pp. 249-254)
Culver's introduction to this section of the anthology applies to the American Realist's generally, but he has enough to say about Holmes, our focus this time, to make the whole of it worthwhile at this point.
Holmes's lecture will be the heart of our discussion. The chapter from Frank is an extended example which illustrates some of the points Holmes makes. Culver's introduction will be a good guide to what you should look for, but pay special attention to the idea of statements of law as predictions, to what Holmes says about the point of view of the "bad man," and to what he says about the role of policy considerations.
If you'd like to read the whole of the Holmes lecture, you can find it in the "source browser" on the course Blackboard site. You can also find a link to it in pdf format at

on the EBSCO site. Culver's selection cites its source as an edition of Holmes's book The Common Law (which was originally published before the lecture was written); you can find plain text versions of both that book and the lecture by way of the page
