Story about a submersible captured on sea floor by underwater race

Question

Ten years ago or more I got a book of short stories out of a library. If I remember correctly is looked old (thick paper, grainy printing) then, so probably an old book.

In the book there was a story about a man (scientist?) who has a submersible. As far as I remember it was connected to his ship via a chain, with a separate telephone (more like an intercom) line. It was lowered using a crane.

I think the telephone cable snapped on the first dive, but he was pulled up again safely. On another dive he describes the fish curiously looking through his window at him. When he nears (or has arrived on) the bottom of the sea he sees a creature coming towards him. I think the creature had fins (I can't remember where, maybe on its back or limbs, or in place of limbs), but was semi-humanoid (it had a head as far as I can recall). The creature somehow cuts his submersible loose, and drags it away. The man inside sees a city on the ocean floor, with lots of similar creatures. There may have been a temple mentioned, if so, I think they took him up to the temple.

There were parts of other larger works in the book, so this also might be part of a larger work. I have read so many similar books, so I can't tell you which stories where in it, but I think there was one about adventurers flying in a dirigible.

"In the Abyss", an 1896 short story by H. G. Wells, available at Project Gutenberg. It has been reprinted in many collections and anthologies; does any of these covers look familiar?

Wikipedia summary:

Elstead has invented an apparatus by which a person can travel to great depths and observe the life on the sea bed. It is a steel sphere, about nine feet in diameter, intended to withstand immense pressure. Weights attached to the sphere by a cable take it to the sea bed. The explorer makes observations through the window in the sphere, oxygen inside being replaced by a fictitious "Myers apparatus". A clockwork mechanism cuts the cable after a certain time, and the buoyancy of the sphere takes it back to the surface.

The sphere is to be lowered into the water from the Ptarmigan, which has sailed to a region where the water is five miles deep. The organization behind the project (perhaps funded by a scientific body, or by Elstead) is not specified.

The details of the sphere, and of Elstead's plan to use it to view the ocean floor, are made clear in the conversations of Elstead and the officers of the Ptarmigan; because of the immense pressure at the depth to be explored, the officers have their doubts about the apparatus working to plan, and about Elstead's likelihood of survival.

The sphere does not return on schedule. While the ship's officers wait, "the December sun was now high in the sky, and the heat very considerable." By midnight, they are fearing the worst; then they spot the re-emergence of the sphere. It is eventually retrieved at dawn.

After a week, Elstead has recovered enough to tell his experiences. He relates the eventful descent, lasting several minutes, during which the sphere became unexpectedly hot. On the sea bed, after observing the unusual species of fish and invertebrates, he sees "a strange vertebrated animal.... The vertical pitch of its face gave it a most extraordinary resemblance to a human being.... It was a biped; its almost globular body was poised on a tripod of two frog-like legs and a long thick tail." This creature, together with others, tow the sphere to a kind of altar in their city; the inhabitants prostrate themselves before Elstead, and chant. He observes this for several hours: eventually the cable breaks and the sphere returns to the surface.

The narrator has talked to eminent scientists, who think such a civilization is quite possible; he further speculates: "We should be known to them, however, as strange, meteoric creatures, wont to fall catastrophically dead out of the mysterious blackness of their watery sky. And not only we ourselves, but our ships, our metals, our appliances, would come raining down out of the night.... One can understand, perhaps, something of their behaviour at the descent of a living man...."

Elstead never writes an account of his experience; after making improvements to the sphere, he makes another descent, but (like The Time Traveller in Wells's The Time Machine) he does not return from his second adventure.
