THE AMERICAN INSTITUTE OF CBEMICAL 

 ENGINEERS 

 A MEETING of the institute is to be held in 

 Pittsburg, December 28 and 29, in the build- 

 ings of the Carnegie Technical Schools. 

 Papers of general chemical engineering in- 

 terest are to be presented ; notable among these 

 ■will be the first technical statement by the 

 inventor, Mr. James Gayley, regarding the 

 process for dehydrating air used in blast 

 furnaces and other metallurgical apparatus. 

 Other papers on the use of fuels and power 

 production are to be presented. The measure- 

 ment of high temperatures and dryer calcula- 

 tions and dryer designs are the subjects of 

 two other important papers. 



One feature of the Pittsburg meeting ■will 

 be the exhibition by manufacturers of novel 

 plants and machinery, partly by drawing and 

 partly by the actual installation for 'tests in 

 the presence of the institute. These exhibi- 

 tions and tests are in no way official in that 

 the institute does not undertake to pass official 

 judgment upon any of the exhibits, and are 

 no more sanctioned or indorsed by the insti- 

 tute than technical papers presented to it 

 would be, but are offered by the manufacturers 

 as a method of acquainting those in charge 

 of manufacturing operations with the latest 

 and best machinery in the various lines. 



Such an exhibit, however, should be an 

 increasing source of breadth and education to 

 the members, and the tests and discussions 

 which will inevitably result from the special 

 installation of machinery for this purpose 

 should do much to unify the judgment of 

 chemical engineers on the question of certain
