The University publishes bulletins six times a month, so 

 numbered that the first two digits of the number show the 

 year of issue ; the last two the position in the yearly series. 

 (For example, No. 1701 is the first bulletin of the year 1917.) 

 These comprise the official publications of the University, 

 publications on humanistic and scientific subjects, bulletins 

 prepared by the Department of Extension and by the Bureau 

 of Municipal Research and Reference, and other bulletins 

 of general educational interest. With the exception of 

 special numbers, any bulletin will be sent to a citizen of 

 Texas free on request. All communications about Univer- 

 sity publications should be addressed to the Chairman of 

 the Publications Committee, University of Texas, Austin.
