PERIODICAL LITERATURE IN IOWA ON THE SUBJECT OP 
CHEMISTRY. 
BY W. S. IIENDEIXSON. 
Two years ago the author published in the proceedings of the Iowa 
Academy of Science a list of the chemical periodicals, then present in 
the libraries in the State. The purpose was, of course, to make known 
the presence of these periodicals to chemists in the state who have oc- 
casion from time to time to use them for reference purposes. Since that 
date many changes have occurred. Some periodicals have been dropped; 
more have been added, and many partial files have been made more 
nearly or quite complete. It seemed best, therefore, to offer a revised 
list for publication in the Proceedings of the present year. 
It is no easy matter to determine just what publications should have 
mention in such a list and which should be excluded. It would require 
too much space to include all periodicals and proceedings of scientific 
societies which contain a few chemical papers. It has been thought best 
to include only periodicals devoted mainly to chemistry as a science. 
For the most part the proceedings of general scientific societies, and 
periodicals devoted chiefly to technology have been omitted. The list does 
not include fragments of periodicals, consisting of only a few volumes, 
unless those periodicals are now being received. 
So far as known the books of any set mentioned may be used for 
reference in the libraries which contain them, and for the most part they 
may be borrowed by non-residents under suitable restrictions. In a few 
cases sets belong to the private libraries of chemists connected with the 
institutions designated, but this does not preclude their use by other 
chemists. 
The chemists of the state are to be congratulated that* it is no longer 
necessary to send to eastern libraries for books from sets of the great and 
much used periodicals. With half a dozen exceptions such periodicals 
may now be had within the borders of the State. I shall name some 
prominent exceptions in the hope that the wants may be supplied in the 
near future by such libraries as may be able to command the resources. 
The following are suggested: 
Gazetta Chimica Italiana. 
Journal fur Praktische Chemie. 
Monatshefte fur Chemie. 
Annales de Chemie et de Physique. 
( 176 )
