Reading up on Medicine's History

Blood and Guts has been very interesting so far. The first chapter is a brief history of disease in humanity, the second chapter a history of healers (doctors). I thought the history of doctors was especially interesting, because the devotion to expertise and professionalism in the Hippocratic oath is so familiar to our idea of doctors now. Even the inaccuracies of classic physiology (the four humors, etc.) reflect the need to have an expert put complex concepts into terms that a layperson can understand, which is part of what the very word doctor means. To me, this makes the field of medicine feel at once both old and new in a very special and exciting way.
The third chapter covers advances in anatomy. What was most interesting about this chapter was that discovering a body part seemed much easier than figuring out what it did. That is, even organs whose form one might think would strongly suggest function were not seen for what they were.
The fourth chapter, on the laboratory, felt more like the medical history I was expecting to read. It went through the development of the laboratory and the physicians gradual entry into the lab. Of special interest to me was Koch's Postulate on how to determine if an organism was responsible for a disease.
