 The Use of the Blue-print in the Teaching of 



Industrial Chemistry : Feancis C. Feakt. 



Instead of the time-honored methods of showing 

 charts or drawing diagrams of machinery on the 

 black-board, the author recommends the use of 

 the lantern-slide and the blue-print: the lantern- 

 slide to be shown to the class, and a blue-print of 

 the apparatus, made from the same negative as 

 the slide, to be given to the student to paste in 

 his note-book. Thus time is saved in the class- 

 room, and the student has a better idea of the 

 apparatus. The system was developed by Dean 



W. R. Appleby, of the Minnesota School of Mines, 

 for use in the teaching of metallurgy, and the 

 author has found it likewise helpful in the teach- 

 ing of industrial chemistry and electrochemistry. 



Proficiency in Qualitative Analysis: H. C. Coopeb. 

 The results of an inquiry among prominent 

 American chemists conducted to ascertain how 

 students can best be prepared to make reliable 

 analyses of miscellaneous materials were reported. 

 It was the majority opinion that the students 

 should be given rather extensive drill in the 

 thorough qualitative analysis of minerals and 

 technical products. Since qualitative analysis is 

 generally taught to freshmen or sophomores, 

 praiseworthy mention was given to the plan of 

 conducting a supplementary course in the subject 

 for the advanced students. Considerable discus- 

 sion was aroused by the question of teaching 

 students to make abbreviated analyses. 



I'oints of View in the Teaching of Industrial 



Chemistry: James R. Witeeow. 



Defining industrial chemistry as the study of 

 the manufacture of chemical substances and the 

 production of commercial products with the help 

 of chemical operations the point of view of the 

 lecture worlt was taken up. Each industry is 

 considered as a problem for the solution of the 

 difBculties of which much work has been done and 

 much remains to be done. The student is also 

 made to analyze each of the industries with refer- 

 ence to operations involved, such as distillation, 

 condensation, filtration, etc. These points of view 

 give the student the desirable attitude of mind 

 which makes him analytically critical of the 

 industries and also makes him scrutinize the 

 methods used to overcome difficulties in a way 

 that makes for increased personal efficiency. With 

 regard to the laboratory work, the usefulness of 

 familiarizing the student with the " tools of the 

 trade " is emphasized, but the mere requirement 

 of such familiarity is by no means the highest 

 object to be obtained. Emphasis is laid rather 

 on the solution of problems in the study of cost 

 and acquiring of data for use in works experi- 

 ments on the manufacture of commercial prod- 

 ucts or utilization of by-products. The difficul- 

 ties arising give the student a keen appreciation 

 of the value to him of the library and all work, 

 whether theoretical or practical, which is within 

 his reach. In a word, the work is industrial 

 research. It shows the student how to attack 

 problems; familiarizes him with the spirit of 

 manufacturing chemistry; gives him the proper 

 attitude of mind toward his science; makes him
