 F.R.S. Second edition. Pp.137. London and New York, 1911 

 (Longmans, Green & Co.). — In view of the large amount of work 

 on enzymes published since the appearance of the first edition of

 able. L. B. M.

 from the Observatoire de Meteorologie dynamique de Trappes, 

 working in collaboration with the Blue Hill Observatory in this 

 country. It gives the results of a study of the ocean atmosphere 

 by means of balloons and kites. The observations were made

 voyages extending from the Azores to Ascension Island in the 

 South Atlantic. Twenty-four ascensions were made with captive 

 balloons, and forty-six with self-registering kites. In addition, 

 ascensions were made for a brief period from the Romanic 

 between Boston and Gibraltar, and from the peaks of Fogo and 

 Teneriffe. An interesting account of the Otaria and the observa-
