On the Size of Pins for Connecting Flat Links in the Chains of Suspension Bridges

This is not a penny dreadful—it is an 1865 scholarly article from what appears to be a scientific journal. The content consists of two papers: the first, by an unnamed author, discusses anatomical observations on the corpus callosum of placental mammals, defending original research against claims of derivation from Professor Owen's work. The second paper, "On the Size of Pins for connecting Flat Links in the Chains of Suspension Bridges" by Sir Charles Fox, presents engineering research on proportioning chain components for suspension bridges. Fox documents experiments on links manufactured for a Russian military bridge over the Dnieper at Kieff, establishing that pin diameter must provide adequate bearing surface rather than merely resist shearing force—a principle previously misunderstood in bridge construction, causing wasteful oversizing of link bodies or undersizing of pins.
