Stone implements

In an 18 September 1873 letter to an unknown recipient, John Evans discussed the notches in stone implements which he believed to be ornamental. He included an impression of one of his samples, a blade pressed into a big red blob of sealing wax. When I first saw it, I thought it was perhaps the abdomen of a grasshopper and that Evans might have been an entomologist, rather than an archaeologist and geologist.
