In Deborah M. Barnes' article "AIDS commission bills proliferate" (News & Comment, 6 Mar., p. 1136), the AIDS commission proposals introduced by Senator Ted Stevens (R-AK) and Representative Jerry Lewis (R-CA) were incorrectly identified as being "along the lines of [those] recommended by the Institute of Medicine in its report ("Confronting AIDS") last fall." Instead, the IOM recommended the "establishment of a presidential or joint presidential and congressional commission that is independent and able to provide an ongoing critical assessment of needs-involving basic and clinical research, health care, public health, and other societal issues-as the AIDS epidemic develops," according to Roy Widdus, director of the IOM Division of International Health. The congressional advisory panel on AIDS, described in a bill introduced by Senator Pete Wilson (R-CA), incorrectly identified its potential membership. It would be open to IOM members, not exclude them, as the article indicates.

In "Nomenclature of Streptomycin Preparations" (Science, March 5) lines 15-16, second column, page 234, should have read "...Streptomyces griseus" instead of ". . . Streptomycin griseus."

In the Books Received column in the issue of 9 December 1994 (p. 1743) the title of the book Polyominoes (2nd ed.; Princeton University Press) was given incorrectly and the name of its author, Solomon Golumb, was omitted. Warren Lushbaugh drew the diagrams in the book.

Solomon Buchsbaum has graciously informed Science that he is still a senior vice President at Bell Laboratories-not a "former executive," as we incorrectly described him several issues ago (25 January, p. 377).     

Correction

Because a line was inadvertently omitted, the article "Reagan reforms create upheaval at NIOSH" (News and Comment, 9 Oct., p. 166) stated on p. 168 that Donald Millar, new director of the National Institute for Occupational Safety and Health (NIOSH), believes that NIOSH should be separated from the Centers for Disease Control in Atlanta. The sentence should have read, "Millar says one of the things he learned as acting director [of NIOSH] is that NIOSH should be moved to Atlanta or that its ties to CDC should be severed." Millar, who wants strengthened ties between NIOSH and CDC, favors the former alternative.

In the report "Motor neuron degeneration in mice that express a human Cu, Zn super-oxide dismutase mutation" by M. E. Gurney et al. (17 June 1994, p. 1772)(1), a systematic, 10-fold error was made in calculating the dilutions of brain extract used for determinations of total brain superoxide dismutase (SOD) activity shown in column 6 of table 1 (p. 1774). Each value reported should have been reduced by that factor, for example, the total SOD activity reported for the G1 line should have been 4.26 +/- 0.2 SOD (U)/total protein (microg), not 42.6 +/- 2.1 U/microg, and so forth.

In my report on the Echo Lakes Symposium on Cosmic Rays (Science, September 2, 1949) the pi- and micro-symbols were interchanged, in the line before last of the second column, p. 242, and in the first line of the third column in the same page. The portion of the text containing these two lines should read: ". . . the latest values for the masses of the micro- and the pi-meson (215 and 285 electron masses respectively) and for the mean life of the pi-meson (0.63x10(-8) see)." In a recent letter to the writer, Dr. Barkas states that this value for the mean life of the pi-meson has been superseded by more accurate measurements. These measurements, made on positive pi-mesons, give a mean life of 1.97x10(-8) sec. Dr. Barkas also indicates that new mass measurements give 276 electron masses for positive or negative pi-mesons and 210 electron masses for positive micro-mesons.

A typographical error in Table 1 of my paper "The Validity of the Use of Tracers to Follow Chemical Reactions" (Science, 1949, 110, 14), under the entries for chlorine makes the estimated maximum ratios for the tracers Cl(36) and Cl(38) somewhat ambiguous. The stable isotopes should be written as Cl (natural abundance). The ratios were calculated for reactions with the tracers Cl(36) and Cl(38) in systems containing chlorine of natural isotopic abundance. Due attention has been given to the fact that the Cl(35) and Cl(37) will react at different rates.

Contrary to what we reported, the horned dinosaur Chasmosaurus (Science, 12 April, p. 207) did not have the largest skull of any land animal. Paleontologist Paul Sereno of the University of Chicago says that honor belongs to Triceratops, another member of the family Ceratopsidae.

In an article titled "How safe is Bendectin?" (31 Oct. 1980, p. 518), it was incorrectly reported that William McBride of Sydney, Australia, was paid $5000 a day to testify as an expert witness in a court case involving allegations that Bendectin caused birth defects in a Florida child named David Mekdeci. McBride was not paid for certain testimony. Rather, he was compensated for time away from his Australian practice at a rate of approximately $1116 a day so that he could appear as an expert witness on behalf of the Mekdeci family. He was also reimbursed for his travel expenses to and from Australia. Science regrets the error.

In the Research News article "A ;mitey' theory for gene jumping" (6 Sept., p. 1093), Jean Marx erred when she wrote that the groups of Marilyn A. Houck and Margaret G. Kidwell (Reports, 6 Sept., p. 1125) focused on Proctolaelaps regalis as a possible carrier of P elements among Drosophila species by a "process of elimination." Viruses were not screened for P elements during the study, as implied, nor were any other organisms. Rather, the work was initiated by acarologist Houck (then on the faculty of the University of Arizona), who was aware of P element history from conversations with the Kidwell lab. Houck and Ken Peterson, a postdoc in the Kidwell lab, then initiated the Southern blot analysis that pointed to the presence of P element DNA in P. regalis, and Jonathan Clark, a postdoc at Arizona's Center for Insect Science, significantly extended the work through the application of polymerase chain reaction. Their data do not exclude the possibility of viral participation in the system, however.

The name of Lewis P. Lipsitt, winner of a 1993 AAAS Mentor Award for Lifetime Achievement, was misspelled in last month's "Inside AAAS." We regret the error.-Ed.

The International Commission on Zoological Nomenclature desires to draw attention to an error in the material it recently issued with respect to proposals submitted to the Commission for the suspension of the Règles Internationales (Science, November 21, 1947, pp. 487-488). On page 488 (item 11), it was erroneously stated that one of the proposals was for the validation of the name Raphistoma Rafinesque, 1815 (Pisces). The application in question was, in fact, that the Commission should suppress the above name and validate the name Raphistoma Hall, 1847 (Gastropoda). The Commission greatly regrets any inconvenience which may have been caused by the erroneous entry referred to above. (FRANCIS HEMMING, secretary to the Commission.).

In the article by Dr. Millikan entitled "The Progress of Physics From 1848 to 1948" (Science, September 3, p. 230) the last part of the fifth paragraph should have read: ". . . Ampere, the Frenchman, in the 1820's had developed that field with great skill and insight; while England's unsurpassed experimentalist, Faraday, had in 1831 discovered electromagnetic induction and in 1834 had laid the secure foundation for the whole field of electrolysis."

In the briefing "Now even mummies go digital" (Science, 7 December 1990, p. 1334), the reconstruction of the mummy's head should have been attributed to Raymond Evenhouse of the University of Illinois at Chicago.

Due to a printer's error, a recent meeting of the Planetary Society in Washington, D.C., was incorrectly identified as a "Planetary Soviet" meeting in the News and Comment article by R. Jeffrey Smith, "A fresh start for arms control" (25 Jan., p. 389).

An article reporting a congressional hearing on the National Cancer Institute (NCI) (News and Comment, 20 Nov., p. 887) incorrectly states that the institute allowed an unnamed individual to produce a preparation called "Jim's Juice" under what is known as a "compassionate investigational new drug" permit. The NCI, which does not have authority to issue such IND's, was not involved in the matter. The article also refers to an internal memo written by an NCI researcher about the alleged misuse of an experimental drug called Mitoxantrone. The drug in question was one known as M-AMSA, a new agent against acute leukemia.
