acters, the latter being defined as characters normally dominant which have gradually 

 disappeared. 



The biology of cestodes, L. Jammes and H. Mandoul (Compt. Rend. Acad. Sci. 

 [Paris'], 140 {1905), No. 4, pp. 271-273). — A brief account is presented of observations 

 regarding the bactericidal power of the serum of cestodes. This group of worms 

 possesses considerable power of this sort and stands in marked contrast with nema- 

 todes in which the serum is not bactericidal. 



Birds in relation to agriculture, Gunning (Transvaal Agr. Jour., 3 (1905), No. 

 10, pp. 222-224, pis- 4)- — Attention is called to the value of birds in the destruction 

 of insect pests especially at times when some pest such as grasshoppers becomes 

 unusually numerous. The thrushes, warblers, and fly catchers are believed to be 

 worthy of protection. 



Our native birds, H. A. Surface (Pennsylvania Dept. Agr., Zool. Quart. Bui., 2 

 (1904), No. 3, pp. 51-64, pis. 2, Jig. 1). — An account is given of the feeding habits and 

 economic relations of the cuckoos, kingfisher, and woodpeckers in Pennsylvania. 



The protection of insectivorous birds, F. Peneveyre (Citron. Agr. Canton Vauol, 

 18 (1905), No. 5, pp. 134-137). — The benefits to be derived from the presence of 

 insectivorous birds are briefly noted, and suggestions are made regarding methods of 

 protecting them. 



Insectivorous birds, A. J. North (Agr. Gaz. New South Wales, 16 (1905), No. 3, 

 pp. 247-250, figs. 3). — A new genus of the order Passeres is described under the name 

 Oreoscopus. These birds are said to be of considerable value on account of their 

 insectivorous habits. 



Injury to trees by the green woodpecker (Jour. Bd. Agr. [London], 11 (1905), 

 No. 11, pp. 693, 694). — Oak, pine, and old fruit trees are considerably injured by the 

 green woodpecker. The bird bores large holes into the trunks of these trees and an 

 examination of a number of these holes fails to show that they are in the vicinity of 

 insect borers. Apparently the bird feeds upon the sap, cambium, and young bast 

 layers. In some instances the woodpeckers eat the callus forming along the edge of 

 wounds. 



Recommendations of State game commissioners and wardens for 1905, 

 T. S. Palmer ( U. S. Dept. Agr., Division of Biological Survey Circ. 47, pp. 12). — In 

 this circular the author presents a digest of recommendations of State game commis- 

 sioners and wardens in different States and Territories in this country. These recom- 

 mendations concern the subjects of big game, shore birds, waterfowl, bag limits, sale, 

 licenses, commissions, propagation, game preserves, and related subjects. 



The monthly bulletin of the division of zoology, H. A. Surface (Pennsylvania 

 Dept. Agr. Mo. Bui. Div. Zool, 2 (1904), No. 8, pp. 227-256; 2 (1905), No. 9, pp. 257- 

 288, figs. 3). — Brief notes are given on methods of studying zoology, winter protection 

 of quail and other birds, combating injurious insects, methods of collecting insects, 

 nurseries in Pennsylvania, the protection of trees from the attacks of mice, rabbits, etc. 



METEOROLOGY— CLIMATOLOGY. 



Proceedings of the third convention of Weather Bureau officials held at 

 Peoria, 111., September 20, 21, 22, 1904 (Washington: Government Printing 

 Office, 1904, pp. 267, j>ls. 13, figs. 40). — An account of the proceedings containing an 

 address by the president, W. L. Moore, and the following papers: Laboratory Work 

 in Meteorology, by A. G. McAdie; The Mount Weather Research Observatory, by 

 F. H. Bigelow; Errors of Meteorological Instruments and the Lines Along Which 

 Improvements Should be Sought, by C. F. Marvin; Long-Range Weather Forecasts, 

 by E. B. Garriott; Seasonal Forecasts, by A. G. McAdie; Amplification of Forecasts 

 for the Benefit of Shippers of Perishable Products, by W. M. Wilson; An Aid in 

 Forecasting, by F. H. Brandenburg; Report of Board Appointed to Consider the
