the southern hemisphere, the description of new forms, and an interesting discussion of the relations of the existing forms to their fossil precursors and their distribution in connection with theories of previous land connections between the different continents in earlier geological time. His conclusion is that the present distribution lends probability to the hypotheses of von Ihering and others which assume such linking up of the various bodies of land in the later Mesozoic epoch. The paper has an excellent bibliography, but it is to be regretted that the phototyped figures in many cases are insufficiently clear to show the details mentioned in the text.

The continued publication of these purely scientific papers before the cessation of active military operations and in despite of financial stresses, reflects credit upon the government of Australia. The citizens of that commonwealth have naturally taken great pride in the success of their expedition and its valuable results for science, and these handsomely published memoirs are an expression in part of that pride.

The number of calcareous sponges from the Antarctic is small, but to them are added a number collected off Tasmania and at Macquarie Island. The collection includes two new species of Leucetta and one of Leucandra.

Dr. Ridewood's memoir contains no species but forms a useful review of the austral species of Cephalodiscus with a bibliography of the rather scanty literature.

Dr. Tattersall treats of four species of Euphausians and two of Myacids, one of the latter from the Auckland Islands being new is described as Tenagomysis tenuipes. Dr. Calman describes a new species of Diastylis and reviews forms of Nebalia and Cyclaspis, which fill a wide gap in our knowledge of their geographical distribution. Dr. Thomson's memoir on the Brachiopoda is of particular importance, comprising a review of the group in

SPECIAL ARTICLES ROTARY VERTIGO IN THE TAIL-SPIN In the tail-spin, an evolution that is standard among military and exhibition aviators and into which any flier is apt to fall accidentally, a marked rotary and post-rotary vertigo may be induced. As the maintenance of the correct flying attitude of the airplane is largely dependent upon the pilot, this disturbance in his idea of attitude may lead to serious consequences and its significance and characteristics merit definition. A true appreciation of the phenomenon should increase the confidence of the young pilot just becoming acquainted with the evolution and decrease the risk attached to this feature of aviation training.

Purkinje in 1820 (quoted from McKendrick) directed attention to the well-known vertigo of rotation. In brief, when the movement of the body is arrested after undergoing rotation

(1) an after-sensation of rotation in the same direction is experienced. In coming out of the spin and levelling off, the pilot experiences a sensation of rotation after that has actually ceased. He therefore, tends to overcontrol, with the consequent danger of falling into another spin in the opposite direction.
