. The honey-makers. Bees. Eyes, Antennae, and Brain 41 when it comes to a near-at-hand object, the bee, as far as they are concerned, is very hkely as bhnd as if it had no eyes. So these twelve or thirteen thousand facets have to be re-enforced by more eyes ; and near the top of the head, between the compound eyes, are three other visual organs arranged in a triangle, ^r^^^yil^'Wx. each one large as compared with a facet, j^^'Vr'V ;7';5f though small as compared with the com- pound eyes themselves. These three simple eyes are overhung by tufts of hairs like very shaggy eye- brows, and when one of them is dis- covered with a magnifying glass, it shines out like a bright bird's eye, the light often focusing upon it in a way to make it simulate the eye of higher animals. These three eyes are not on the same plane, and it is difficult to see all of them at the same time, because of the hair that covers the top of the bee's head. This hair can easily be shaved off, however, as has been done in the illustration. The central eye is lower than the two others, and is somewhat to the front of the face ; it is directed up and out, so that while the two compound eyes are busy searching space for flowers on either side, this forward-looking eye perhaps prevents the eager worker from bumping its reckless head against obstacles close in front. The two other eyes are over the edge, as it were, resting in slanting depressions on top of the head, and being directed upward and to the right and left respectively. The structure of the simple eyes, or ocelli, is somewhat similar to that of the facets, but is simpler, and the lenses are shaped for near vision. Though in some cases they do not seem to perform their part with remarkable success, they doubtless have their Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original w
