Report of the chemical control station, Trondhjem, Norway, 1902, E. 

 SoLBEKd (.{arsher. Offeiit. ForcuiMalt. L<tnilhr. Fri'imni', l:)i)..', jiji. J4'<~300). — Several 

 lines of work are reported upon l)riell\ . 



^Maximum and minimum data for 151 samples of l)utter from (5 Norwegian cream- 

 eries are as follows: Specific; gravity 0.8632 (June) and ().S672 (January); index of 

 refraction 39.1 (December) and 43.1 (June); Reichert-Moissl nuud)er 21.6 (June) 

 and 33.9 (December). The water content of 63 samples was as follow's: Minimum 

 10.33, maximum 17.2."i, and average 12.71 per cent. The additi(jn of potassium 

 bichromate to milk samples did not affect the determination of fat by the Adams or 

 Lindstrom methods for a period of at least 2 months. 



Comparative tests of different methods of determining fat in feeding stuffs are 

 reported and analyses oi l)arley, rye, potatoes, and other crops are given. 



A number of fertilizer experiments with pastures, cereals, and ])Otatoes are 

 reported. In the experiments with potatoes the effects of fertilization with sea weeds 

 were studied, mixtures of Fucus nodosus and F. vesiculosns, Laininaria diijitata, etc., 

 and eelgrass {Zostera imtrliia) were applied either alone, at the rate of 7,200 kilos i)er 

 10 are (4- acre), or in connection with nitrate of soda and superphosphate. The 

 results did not agree with those obtained in similar trials during the preceding season, 

 and therefore do not permit of generalization. 



The report of the control work of the station contains summary statements and 

 discussions of analyses of the usual agricultural products. — f. w. woll. 



Report of the chemical control station and the seed control station, Chris- 

 tiania, Norway, 1902, S. Hals {AmsJn'r. Offeid. Fomuxtidt. Lundhr. Frcmiiw, ino,?, 

 pp. 1'j8-24S). — The report contains the usual summary of results oljtained in the 

 examination of feeding stuffs, fertilizers, soils and soil amendments, food materials, 

 etc. Brief accounts of analyses made in special investigations of barley, root crops, 

 potatoes, and peat fuel are also given in the report. 



The report of the seed control station during the year contains statements of 

 analyses of 1,287 seed samples and also an account of the system of agreement with 

 seedsmen, arranged for by the station, by which free-seed examinations may be had 

 by all buyers of good?, the price of which exceeds 25 kroner ($6.70), with a cojjy of 

 the contract made Ijetween the station and the dealers, and the rules governing the 

 examinations of seeds. — f. w. woll. 



Concerning the nomenclature of enzyms, E. O. vo.\ Lippmaxn {Ber. Deut. 

 Chern. Gesell., 36 {1903), No. 2, pp. 331, 332). — In view of the confusion which exists 

 in the names of enzyms, the author proposes a system of compound names in which 

 the first part shows the substance acted upon and the second part the principal 

 product produced; for instance, the name of the enzym producing maltose frorfi 

 starch would be amylo-maltase.

ZOOLOGY. 



Report of the New York Zoological Society for 1903 {Eighth Ann. Rpt. 

 Neir York Zool. ,Soc., 1903, pp. 216, pis. 27, figs. 20). — As in previous reports of this 

 society, lists are given of the officers, managers, members, etc., of the society, 

 together with a detailed report l\v the director, W. T. Ilornaday, and special articles 

 on the care and diseases of various animals in confinement. 



Experiments were carried on for the ])urpose of determining whether oysters could 

 be readily infected with typhoid bacilli. C. W. Field, who did this work, found that 

 while typhoid bacilli were destroyed to a considerable extent by the action of fresh
