An abridged version of The Principles of Humane Experimental Technique
The Three Rs and the Humanity Criterion is a revised and updated version of The Principles of Humane Experimental Technique, written in 1959. To mark the 50th anniversary of the original book, the FRAME Chairman has published an abridged version with permission from Cleo Paskal, Literary Executor and now owner of the copyright. The title for the new book is taken from the text of the original version. The new book is shorter and has more modern language so it is easier to read.
