Erratum

In the report "Aflatoxin production by a variant of Apergillus oryzae (NRRL strain 1988) on cowpeas (Vigna sinensis)" by N. El-Hag and R. E. Morse [192, 1345 (1976)], the third sentence in the legend to Table 1 should read "This strain produced aflatoxin on rice (expressed as micrograms per kilogram ...)." Also, the heading for columns 2 and 3 of Table 1 should read "Aflatoxin (microg/kg) from A. oryzae."     

Erratum

In the report "Fatty acids ... smooth muscle cells" by J. J. Huttner et al. (15 July, p. 289), Table 1 was reset after the authors had approved their galleys. Through faulty proofreading at Science, an omitted line was not detected and the table as printed is meaningless. The body of Table 1 should read.     

Errare humanum est

In the erratum published in the issue of 13 February (p. 656), Tables 1 and 2 from the report "Mutagenicity of fly ash particles in Paramecium" by J. Smith-Sonneborn et al. (9 Jan., p. 180) were printed incorrectly. Significance lines missing in the original tables were also missing in the erratum. With determination, we again reprint the tables as they should have appeared (Table 1 above, Table 2 at right).     

Aboriginal Indian residence patterns preserved in censuses and allotments

Early reservation annuity censuses and allotment ledgers, analyzed in concert, allow identification of sociologically significant subdivisions of Native American tribes. Using this method, Southern Cheyenne manhao or "bands" can be located on the allotment map of 1892 as discrete clusters of individuals known by name, age, and sex. Measurement of linear distances among individual allotments of family members enables us to quantify jural rules of postmarital residence and confirms in a test case that the descendents of the bands at the Sand Creek Massacre in fact resided matrilocally.     

Erratum

In Table 1 of the report "Monoclonal antibody to Thy-1 enhances regeneration of processes by rat retinal ganglion cells in culture" by D. Leifer et al. (20 Apr., p. 303), the unit of measurement, micrometers, was omitted in the third column, "Mean length of processes per cell."     

Erratum

In the news article, "More seismic research asked to improve atomic test detection" [Science 130, 26 (3 July 1959)], the second figure in column 2 of Table 1 should have been 1500, not 20-100.     

Mechanism of Antibody Synthesis: Size Differences between Mouse Kappa Chains

In the report "Mechanism of antibody synthesis: size differences between mouse kappa chains" by W. R. Gray et al. (27 Jan., p. 465), the headings of the final two columns of Table 1 should be reversed to read "Transversions" and "Transitions."     

Erratum

In the report by H. Vasken Aposhian on "Protection by d-penicillamine against the lethal effects of mercuric chloride" [Science 128, 93 (11 July 1958)], the heading of the last column of Table 1 should have been "Percent," and not "Survival (%)." Mortality, and not survival, is given in this column.     

Erratum

Table 3 of the report "Seroprevalence and epidemiological correlates of HTLV-I infection in U.S. blood donors" by Alan E. Williams et al. (29 Apr. 1988, p. 643) contained errors. The correct table is printed below. [See Table 3 in Source Pdf.].     

Erratum

In the report "Transcontinental baselines and the rotation of the earth measured by radio interferometry" by I. I. Shapiro et al. [186, 920 (1974)], the heading for columns 5 and 6 of Table 1 should read "Atomic time-universal time (A.1-UT.1)" and the second entry of column 1 should be followed by a double dagger (double dagger).     

Lactate dehydrogenase isozymes: further kinetic studies at high enzyme concentration

In the report "Lactate dehydrogenase isozymes: Further kinetic studies at high enzyme concentration" by Thomas Wuntsch, Raymond F. Chen, and Elliot S. Vesell [169, 480 (1970)], 14.0 mM NAD in line 2 of the heading of Table 1 should read 14.0 , microM NAD.     

Inhibition of the Effect of Some Carcinogens by Their Partially Hydrogenated Derivatives

The names of the compounds in the last three lines of Table 1 in "Inhibition of the effect of some carcinogens by their partially hydrogenated derivatives" by Kotin, Falk, Lijinsky, and Zechmeister [Science 123, 102 (20 Jan. 1956)] should read dihydrodibenzanthracene, decahydrodibenzanthracene, and perhydrodibenzanthracene.     

在《中图法》A大类后应恢复领袖著作的“写作年代表”

指出了《中图法》第4版A大类后删除“马克思、恩格斯、列宁、斯大林、毛泽东部分著作写作年代表”的不足，及由此带来的不便。主张应恢复原表，并相应增加“邓小平部分著作写作年代表”，以利于同类书按写作年代顺序排。     

Erratum

In the report by N. Yamamoto et al., "Transformation of human leukocytes by cocultivation with an adult T cell leukemia virus producer cell line" (20 Aug., p. 737), the column headings in Table 1, on page 738, under "Cells with markers (%)," should have read: Leu 1, Leu 2a, Leu 3a, Leu 4, and Ia (not immunoglobulin A).     

Erratum

In Table 1 (p. 351) of the report "Structure-activity studies of interleukin-2" by F. E. Cohen et al. (17 Oct., p. 349), reference 15 was incorrectly cited for the entries for the 1-29, 30-49, and 100-133 deletion mutants. For all three entries, the reference should have been (16).     

Erratum

In the report "DNA amplification for direction detection of HIV-1 in DNA of peripheral blood mononuclear cells " Chin-Yih Ou et al. (15 Jan., p. 295), the fourth sentence of reference 21 (p. 297) should have read, "The PCR reaction mixture contained 1 microg of PBMC DNA, 100 pmol each of primers (Table 2), 200 microM each of four deoxyribonucleoside triphosphates, 10 microM tris-HC1, pH 8.3, 50 mM KC1, 2.5 mM MgCl(2), 0.01% gelatin and 0.6 unit of thermoresistant DNA polymerase of Thermus aquaticus."     

Erratum

In the report "Cloud droplet deposition in subalpine balsam fir forests: Hydrological and chemical inputs" by G. M. Lovett et al. (24 Dec., p. 1303), two errors appeared in Table 2 on page 1304. The cloud deposition of SO(4)(2-), incorrectly reported as 275.8 kg ha(-1) year(-1), should have been 137.9 kg ha(-1) year(-1). The percentage of the sum contributed by clouds, reported as 81 for SO(4)(2-), should have been 68.     

Erratum

Table 1 of the report "Reversible cleavage and ligation of hepatitis delta virus RNA" by H.-N. Wu and M. M. C. Lai (3 Feb., p. 652) contained an error. The religation percentage when the concentration of Mg(2+) in the cleavage reaction was 2.4 mM and the concentration of EDTA was 3.0 mM should have been 10. The correct table is printed below.     

新疆兵团盐渍化农田现状与防治对策

为了研究新疆兵团土壤盐渍化现状问题,2015?2017年基于盐碱地划分标准设计了盐碱地分类面积表、盐碱地化学类型表、不同程度盐碱地生产状况表和盐碱地改良状况表等4份调查表,对139个团场进行盐渍化调查。调查结果表明,兵团盐渍化农田面积约为53.1万hm²,占总播种面积（120.2万hm²）的44%,盐渍化耕地中约23.2%为原生盐渍土,76.8%为次生盐渍土;硫酸盐型、氯化物型、苏打型和碱土型盐渍化耕地的面积分别为16.19万、5.85万、20.65万、10.41万hm²,分别占兵团盐渍化土壤面积的30.5%、11.0%、38.9%、19.6%。次生盐渍化普遍造成作物减产,化肥和有机肥投入量随着盐渍化加剧而增加。目前,盐碱地治理的方法有水利改良、农业改良、生物治理和化学改良,但是不同改良方法的改良效果差别较大,水利措施和农业措施改良效果较好。为防治土壤盐渍化,需建立兵团耕地质量数据库和兵团盐渍化农田综合治理领导小组,联合疆内外高校共同开展技术攻关与技术集成。
