60 Scientific Intelligence, 



plates, containing 247 portraits and facsimiles. London, 1921 

 (Henry Sotheran & Co.) . Volume I, pp. 428, volume II, pp. 429- 

 964. — The very comprehensive character of this work will be 

 appreciated from the fact that the total number of titles included 

 runs up to about 17,400. The subject index, in addition, covers 

 nearly one hundred pages ; this embraces some titles not included 

 in the body of the volumes. The work was begun in 1906, and 

 the catalogue has grown very largely since that time. It fairly 

 claims to be the first Historical Catalogue of Science published 

 in any country, giving bibliographical particulars, and many 

 biographical and historical references; the current prices are 

 also added. The credit for initiating the work is given to 

 Dr. Heinrich Zeitlinger, of Linz on the Danube. . It is, in fact, 

 a remarkable catalogue embracing, as it does, the subjects of 

 mathematics, astronomy, physics, chemistry and allied fields and 

 nearly all the standard works and most of the earlier works of 

 historical importance. The interest of the volumes is much 

 increased by the large number of plates, 127 in all, which are 

 reproduced from the works themselves by a photographic process, 

 and hence have a peculiar quaint historic interest; many are 

 given here for the first time.

 Zoologie welche in den periodischen Werken enthalten und vom 

 Jahre 1861-1880 selhstdndig erschienen sind; bearbeitet von Dr. 

 0. Taschenberg. Lieferung 20. Leipzig (Wilhelm Engelmann). 

 — Since the notice (vol. 1, p. 519) of parts 21 to 23 of this import- 

 ant work. No. 20 has been received. It bears the date of 1913 

 and includes signatures 745 to 754. pp. 5993 to 6072. It is 

 announced that only some 450 pages, including the Index, remain 

 to complete the whole. In view of the very high present cost of 

 publication it is to be hoped that all the subscribers to this unique 

 and exhaustive work v/ill do their part in full. 



5. Annual Report of the Field Mnseum of Natural History 

 for the year 1920 ; D. C. Davies, Acting Director. Pp. 371-440, 

 with numerous plates. Chicago, 1921. — This report has a pecu- 

 liar and indeed melancholy interest from the fact that Dr. Skiff, 

 the able and energetic director since 1894, died on February 24, 

 1921 (this Journal, 1, 380.) The work here recorded, however, 

 came under his supervision and is most important since it marks 

 the completion of the new building and the transfer to it of all 

 the collections. The magnitude of this work will be appreciated 

 from the fact that 354 loads were transported by motor trucks in 

 addition to the transfer by rail, which last was accomplished in 34 

 working days.
