In many birds, and especially in birds of prey, there is a ring of bones surrounding the pupil of the eye. It is there- fore best—unless you are an expert—not to remove the eye- ball, but to simply i^uucture it to allow the escape of its fluid contents. Eemove the brain carefully. In making the skeleton into a bundle for pack- ing, bend the neck backward, detaching the skull if necessary, and fold the legs and wings closely alongside of the body. SPECIAL POINTS. Cormorants have a small bone attached to the back of the skull, and in Auks and many similar birds there is a small bone at the el- bow. Sometimes there is a little bone at the hinder angle of the lower jaw, so that it is a good rule not to trim up a bird's skull too closely. The easiest, and in many ways best, way to collect small birds is to place them entire in alcohol first making an incision in the lower, j)art of the abdomen to allow the alcohol to reach the viscera. Alcohol should not be used of full strength (95°), the proper proportion being one-quarter water and three-quarters alcohol. TURTLES. In order to rough out a turtle it is usually necessary to remove the under shell or plastron, although some species, such as certain of the large land tortoises, can be roughed out with- out doing this. In sea turtles and a few others the plastron can be cut loose by taking a little time to the operation, but in the more solidly built tortoises and.
