Deaths Mrs. Harvey F. Mack, retired chairman of the board of Mack Printing Co., Easton, Pa., died on Jan. 25 of a heart attack in her home. She was 88. Widow of Harvey F. Mack, the company's founder, Mrs. Mack worked with her husband to build the family company from a small printing shop of 22 employees in 1902 to a leading publishing house of scientific journals. (Chemical & Engineering News, in addition to many other ACS publications, is printed by Mack Printing Co.) Mrs. Mack became chairman of the board of the company upon her husband's death in 1956, a post she held until her retirement in 1972. Ruth Reynard, an editor with ACS for 18 years, died of cancer on Jan. 27. Ruth joined the publishing staff of the society in 1957 and for several years was manager of manuscript editing for the publications. From 1969-71 she was special assistant to the publications manager. The past four years she was assistant to the director of the society's Books and Journals Division. She was 51. DeWitt O. Myatt, 59, editor and chief executive for Science Communications, McLean, Va., died on Jan. 23 of a heart attack. Myatt was managing editor of Industrial and Engineering Chemistry from 1946-53. He was born in Frankfort, Ky. A professional engineer, he received his M.S. in chemical engineering from the University of Louisville in 1938. He is survived by his wife, Emily, and five children.

Further data casting a doubtful light on the importance of the nitric oxide ozonolysis are the equilibrium between this reaction and the photodecomposition of nitrogen dioxide:
N.Y. section symposium The ACS New York Section is planning a symposium on "Insights into Inorganic Chemistry: Synthesis, Structure, Reactions" on March 21 at the Hilton Inn, Tarry town, N.Y. This symposium will be held in conjunction with the 1975 Nichols Award to be presented to Dr. F. Albert Cotton of Texas A&M University. Regular admission to the symposium is $10 (or $8.50 when purchased with a banquet ticket; banquet ticket is $16.50), student admission is $5.00. Tickets may be obtained from Bro. William Batt, Manhattan College, Riverdale, N.Y. 10471, or purchased at the door.
Meeting-in-miniature Abstracts of papers for the New York Chemistry Students' Association's 23rd Annual Meeting-in-Miniature are being solicited from undergraduates in the New York metropolitan area. The meeting will be held at Queens College, Flushing, N.Y., on April 12. The luncheon guest speaker at the meeting will be Dr. Hubert N. Alyea of Princeton University. Abstracts should be sent to Christine Peterson, Department of Chemistry, H. H. Lehman College, Bronx, N.Y. 10468.
Roussel Prize Nominations are being solicited for the 1976 Roussel Prize. This international prize of $10,000 is awarded every two years to a chemist or a biochemist whose work has been chosen as the best by an international committee of outstanding scientists in the field. The
Letters Continued from page 3 the increasing concentration of nitrogen dioxide as a function of distance from the stack, could in fact be generated solely on the basis of the hydroxyl radical/sulfur oxide reaction chain steps:
HS0 3 + HS0 5 + NO HS0 4 + HS0 6 + NO
0 2 —•• HS0 5 — • HSO4 + N0 2 0 2 — • HS0 6 — • HS0 5 + N0 2
N0 2 + 0 2 — * NO + 0 3 I submit that an alternative explanation of the observed ozone depletion is compatible with the experimental data cited in the article. Namely, that there is virtually no ozone present in the plume as it exists in the stack. Simplistically, the plume may be viewed as a cone of hot gases and particulates having its apex at the stack orifice and opening as a function of meteorologic and terrain conditions. The gases comprising the plume are the end products of, in this case, the combustion of fossil fuels; and as such only minimal amounts of ozone should be present. As the plume travels downwind from the plant it both cools and diffuses into the surrounding air, thus creating a physically larger but less concentrated plume. During the diffusion process the plume will naturally increase in ozone content through mixing with the ambient air; this process will continue until the ozone content within the plume reaches that of the ambient. Additionally, the diffusion will make an increasing amount of oxygen available for the photolytic decomposition of nitrogen dioxide formed within the plume. This increased oxygen concentration should shift the equilibrium of the photolytic decomposition of nitrogen dioxide in favor of ozone formation as long as nitrogen dioxide is available for reaction. When the nitrogen dioxide is depleted, the ozone concentration should gradually decrease back to ambient level as a function of distance from the stack and weather conditions.
