I have added to the number of articles on herpetology extracted from Water Life and The Aquarist and Pondkeeper. You can find them on the Download Page.
Of particular interest is an article by Audrey Noël-Hume on African hinged tortoises (Water Life volume 11 No 6, Decmber 1956-January 1957).
Kenneth Blackwell wrote on Marine Toads in volume 12. I think this must be the Kenneth Blackwell who published articles from Wellingborough Zoo in the early 1960s. There are also articles by Robert Bustard and Alfred Leutscher. Two authors describe some pretty crude methods of building and heating vivaria.
