Vintage Russian medical school slides – Embryology. These are long lived birdsThis is an interesting and unusual item. It was part of a collection that must have originated in a Russian medical school. This is a box of 25 prepared slides of sections of human glands including sagittal section of rat embryo, human amnion, trout embryo etc. The slides are in pretty good condition as is the original box.
