The captain and the sea serpent

Transcript

The captain took a harpoon. Ahead of his boat, something long and sinuous seemed to move through the sea. It even appeared to have a head and a mane. This is a story Philip Henry Gosse reproduced in The Romance of Natural History. The encounter was reported in February, eighteen forty-nine, after Captain Herriman sailed from the Cape of Good Hope. From his ship, the object looked twenty-five or thirty feet long. Herriman called over his chief officer and several passengers. They agreed: it looked like a sea serpent. Herriman had already read about a famous sighting in the same region. Now, he thought, he might be looking at the same kind of creature. But the ship was becalmed. He had a boat lowered, took a small party with him, and went to look. Up close, the monster became an immense piece of seaweed. The root mass had looked like a head. The current and the lingering swell had supplied its lifelike motion. According to the account, Herriman admitted that without that closer inspection, he would have remained convinced. The story ends with a captain changing his mind. The sea had offered a shape. An earlier story had supplied the monster. A closer look gave him something better: an answer.

  1. A sea serpent. Or so it seemed.

    In 1849, Captain Herriman spotted a long, strange shape off the Cape of Good Hope.

  2. They all saw a monster.

    The chief officer and passengers agreed. Herriman had read of another sighting in these waters.

  3. He went closer.

    With the ship becalmed, Herriman took a boat and a harpoon to investigate.

  4. The monster was seaweed.

    A tangled root mass looked like a head. The current and swell made the long strands seem alive.

  5. A closer look changed his mind.

    Without the boat trip, Herriman said he would have remained convinced. The sighting survived—as a lesson in checking.

The mammal whose eggs were doubted

Platypuses lay eggs. An 1883 book still doubted it, despite Indigenous reports. This illustrated story follows the gap between knowledge and scientific acceptance.

  1. A mammal. With eggs.

    Platypuses lay eggs. But an 1883 natural-history book still suggested their young were born alive.

  2. The reports were already there.

    The book recorded Indigenous reports of eggs, then doubted them.

  3. 1884: egg-laying confirmed.

    William Caldwell’s collecting work depended on Wakkawakka people’s knowledge and help.

  4. Knowledge came before acceptance.

    The platypus story is also about whose observations were believed.
