"Medical Inquiries and Observations, Vol. 3" by Benjamin Rush is a book from the 1800's where you will learn about the science of fevers. Starting with the idea that fevers come from weakness in the body, Rush uses his experience as a doctor to explain the different reasons behind them. He examines conditions and unusual triggers that can cause someone to get a fever. He then talks about how the body's weakness, excitability, and different triggers all work together to create the many forms and signs of fevers. He tries to create a single idea that explains what fevers are all about by looking closely at how they show up, how to treat them, and by looking at past cases and situations.
