#BIO60: Anonymous Person’s Callus from their Palm

A person that wanted to be kept anonymous was playing with a callus on their palm while in my dorm room. The callus was eventually torn off, and they volunteered to put it on a slide for me. The callus was not recently washed and therefore still had visible dirt marks. In addition,  some of the skin had yellowed due to the death of the skin cells. There were multiple layers of the skin, so it was difficult to focus the foldscope.
