In an article on “Limestone and the Origin of Feldspathoidal Rocks”, which appeared in the Geological Magazine ten years ago, I referred to the malignite of Poohbah Lake, Western Ontario, and was so bold as to predict that “further work at Poohbah Lake … will eventually furnish evidence of the presence of limestone in contact with the alkaline eruptives”,1 In August, 1939, I found myself at last in a position to visit the locality and see how far my prediction could be verified.
