Abstract
IN view of the strenuous efforts now being made by education authorities in this country to economise on educational expenditure, considerable interest attaches to Prof. Egerton Grey's letter on the application of micro-chemical methods in the teaching of chemistry (NATURE, September 2, p. 309). During the War we conducted a course of practical instruction in chemistry in the Internment Camp for Civilian Prisoners of War in Ruhleben, and the difficulty of procuring large quantities of reagents led to the adoption of “Micro” methods wherever possible. Although we had at times forty students preparing for university examinations, the consumption of chemical reagents was extremely small in comparison with what would be required in the ordinary way. To give just one example, half a litre of nitric acid—a precious liquid in the camp—was found sufficient to supply the needs of these students for several months. One enterprising student fitted for himself a, fully equipped “micro” laboratory in a tiny corner of his loft and undertook interesting research work.
