Pity poor Dr Bernard Heuvelmans! He wrote In the Wake of the Sea-Serpents before the advent of the internet, which means he had to carefully cull bits and pieces of information from the far corners of the world, squirreled away in obscure newspapers and magazines, often having to rely on brief summaries in secondary sources. These days, at least in Australia, you will find the vast majority of newspapers, even minor local ones, digitalised on Trove to at least 1955. This means that a some casual references made by Heuvelmans can be investigated in more details. Let's try a few.
