On the origin of inflammation of the veins and of the causes, consequences, and treatment of purulent deposits

"On the Origin of Inflammation of the Veins" by Henry Lee is a medical study from the 1800s that looks at how veins get inflamed. It explores the ways that infected materials in the blood can cause problems, leading to an understanding of the illnesses involving veins. The book starts by looking at what people used to think about illnesses related to blood and challenges the idea that not enough attention was given to fluids in the body. Through describing experiments, Lee shows how pus changes the blood and focuses on what leads to trouble in the body.
