ACCIDENTAL VARIATION.

To the Editor of the Popular Science Monthly.

The following figures and description show a somewhat interesting case of accidental variation:

The antlers are those of a common deer (Cervus Virginianus). The buck from which they were taken was about five years old, and was shot by a gentleman of long and varied experience as a hunter; he thinks them quite exceptional in shape.

Fig. 1.

In their dimensions and their great width, as compared with thickness, they show a strong resemblance to the palmated antlers of the caribou, or an approach to the antlers of the elk.

Fig. 1 shows the position and curvature of the antlers. As indicated, they differ somewhat in outline, and the left one is shorter and broader than the right.

Fig. 2 is a reduced sketch obtained by tracing the outlines of the left antler on a large sheet of paper, and then corrected by careful measurements with calipers.

The measurements are:

WHO ERECTED STONEHENGE?

To the Editor of the Popular Science Monthly.

When a boy, the writer walked many miles to visit Stonehenge. He was utterly alone with these hoary ruins on that treeless plain, and retains, after a third of a century, a vivid reminiscence of the scene and its suggestions.

The attribution of these remains to the
