I found a old magazine with medical pictures, and I was wondering what most of them were used for !!
I cannot think of the reason's to use the two examples I have posted here.
These must be around the late 1800's or early 1900's and I would think not all the people who dabbled in medicine would have known much about it. Everything was trail and error, like in most things in thier history.
If you have any idea what these things were for , please contact me.
