Friends of the late Karl P. Schmidt, Curator Emeritus of Zoology, 

 established a Fund in his name, the income from which is to be 

 used in assisting scholars to study at the Museum (see March 

 and July issues, 1958, of Chicago Natural History Museum Bulletin). 

 Awards will be made by the Trustees of the Fund, who have turned 

 over to the Museum for investment purposes the sum of $6,125 

 (see also Annual Report 1957, pages 30 and 33). 



LECTURE PROGRAMS FOR ADULTS 



The 109th and 110th illustrated lecture series in the Museum pro- 

 gram were presented during the year in James Simpson Theatre 

 of the Museum. These series drew a total attendance of 17,042 

 persons, slightly more than the attendance of the previous year. 

 As usual, many letters of thanks for these lectures, which are pre- 

 sented free of charge through the provision of the Edward E. Ayer 

 Lecture Foundation, were received. So also were many letters of 

 comment and commendation. A typical letter states, in part: 

 "For ten years I have been attending the Saturday afternoon lecture 

 series and have been delighted with the top-caliber speakers. I can 

 appreciate how much effort goes into setting up a well-balanced and 

 visually effective program, I think the enthusiasm and loyalty of 

 the audience reflect the success of these programs and that you 

 can be well satisfied that all the time and effort and planning that 

 go into the series are worthwhile." The Museum will continue in 

 its efforts to secure the best speakers available and to present to its 

 audiences subject-matter of unusual interest. These popular series 

 of free lecture-programs are held on Saturday afternoons in March 

 and April and in October and November.
