laneous assignments (including slides for presentation on television, 

 layouts for exhibits, paintings for exhibition, posters, maps, charts, 

 and retouched negatives). E. John Pfiffner, Staff Artist, completed 

 a painting of Gunnera magnifica, a most unusual tropical plant, for 

 the series of murals (see page 56) in Martin A. and Carrie Ryerson 

 Hall (Hall 29, Plant Life). Miss Marion Pahl, Staff Illustrator, 

 spent a great amount of time in preparing drawings of histerid 

 beetles to illustrate a Museum publication, painstaking work that 

 entails constant use of the microscope and calls for extreme care and 

 infinite patience as well as the ability to turn out precise and accurate 

 material as an aid to scientific study. 



PUBLICATIONS AND PRINTING 



For the third successive year a new record in gross income from the 

 sale of Museum publications was achieved. In addition, the distribu- 

 tion of publications without charge through exchange agreements 

 with other scientific institutions reached a new peak. A total of 

 75,715 copies was distributed, of which 22,340 were sent out as 

 exchanges and 53,375 were sold. The increased burden from the 

 continually increasing quantities of publications distributed was 

 handled smoothly and efficiently through the splendid teamwork of 

 Raymond A. N. Gomes and Miss Hilda Nordland of the Division 

 of Publications. 



The increased production itself called for co-operation of our 

 many authors with Associate Editors Lillian A. Ross and Helen A. 

 MacMinn and Assistant Editor Martha H. Mullen. All employees 

 in the Division of Printing may well be proud of their part in the 

 expanding publications program. 



The Museum issued during the year twenty-nine publications 

 in its scientific series, one in its popular series (reprint), two hand- 

 books (one a reprint), one guidebook, and one annual report. Of 

 these, the number of copies printed by the Museum Press totaled 

 43,268 from 2,104 pages of type composition. Twelve numbers of 

 Chicago Natural History Museum Bulletin were printed, averaging 

 7,250 copies an issue. Other work included posters, price lists, 

 lecture schedules, programs, labels for exhibits, picture postcards, 

 stationery, specimen tags, and Museum Stories (see page 32), 

 totaling 1,069,799 impressions. 



Publications issued by the Museum in 1958 are listed on the 

 following pages. Titles of articles by staff members printed in
