illustrate the very complete provision for higher educa- 

 tion provided by the London polytechnic institutions. 

 In both the day and evening classes at Chelsea, 

 students can prepare for degrees at the University of 

 London under favourable conditions. In the day col- 

 lege those students who enter for technical instruction 

 should have received previously, the prospectus points 

 out, a sound English education and should have 

 acquired an elementary knowledge of mathematics, 

 and, if possible, of physics and chemistry. The 

 courses are arranged to occupy three years. On enter- 

 ing the student states whether he wishes to be trained 

 as a mechanical or electrical engineer, or as a consult- 

 ing or industrial chemist. In any of these cases he 

 will find mapped out for him a complete course of 

 studv, involving laboratory instruction and instruction 

 in tlie workshops. Students, having completed a three 

 vears' course, should be in a position to obtain situa- 

 tions, in many cases without payment of premium, 

 in important industrial firms. Similarly in the even- 

 ing classes, instruction is provided in a wide range 

 of scientific, technological, and other subjects.
