 essential in character. 



11. The Birds of the Chicago Area; by Frank M. Wood- 

 ruff. The Chicago Academy of Sciences. Bulletin No. VI of 

 the Natural History Survey. Pp. 221, with 10 plates. Issued 

 April 15, 1907. — The area embraced in this catalogue is about 

 fifty miles square and includes all of Cook and Du Page counties 

 with the nine north townships of Will County and a portion of 

 Lake County, Indiana. It is of varied character and is particu- 

 larly notable for its birds, since it lies on the border between the 

 eastern ranges of many species as well as being in the path of the 

 Mississippi Valley migration. It is not surprising, therefore, that 

 the list of birds here included is unusually large for a single dis- 

 trict. 



12. The Seventh International Zoological Congress. — The 

 International Zoological Congress will meet at Boston on Aug. 

 19-23. The meetings of sections will be held at the Harvard Medi- 

 cal School on the successive days named. Saturday, August 24, 

 will be devoted to an excursion to Harvard University, and on 

 the succeeding days arrangements have been made for visits to 

 Woods Hole, Columbia University, and the American Museum, 

 to Yale and Princeton Universities, with excursions also to Phil- 

 adelphia, Washington and Mt. Vernon, and other points ; these 

 will occupy the time from Aug. 25 to Sept. 6. In addition there 

 will be a trip to Niagara Falls, across Lake Ontario to Toronto, 

 Sept. 7-9. Finally, an excursion to Bermuda is planned, in case 

 fifty members enroll themselves for it. This last extends the 

 meeting of tbjs Congress until September 22d. Information may 

 be obtained from Charles H. Townsend, Director of the New 

 York Aquarium, Battery Park, N. Y. 



13. Centenary of the Geological Society of London. — The 

 Geological Society of London, the oldest geological society in 

 existence, was founded in 1807. It is now to celebrate its Centen- 

 ary, on the 26-28th of September next, and the occasion promises 

 to be one of very great interest. The Society had its beginning 

 when geology was in its infancy, and during the past one 

 hundred years it has been always in close connection with the 

 development of the science and by its active work has con- 

 tributed very largely to its advancement. 



14. JVeues Jahrbuch fur Mineralogie, Geologie, und Palaon- 

 tologie. — The honored Jahrbuch, which for a century has been 

 one of the chief supports of working mineralogists and geol- 

 ogists, is now in its one hundredth year. This notable event is 

 to be celebrated by the publication of a Festband, which will 

 soon be presented to all its subscribers.
