When, having reached the dining-room of the _Flying Fish_, Mildmay changed out of his diving-suit into his ordinary clothes, it was found that he was so severely bruised and strained that the professor, in his capacity of emergency medical adviser to the party, insisted upon his immediate retirement to his cabin and his bed. There the worthy man subjected him to so vigorous a massage, and so generous an anointing with a certain embrocation of his own concocting, that two days later the genial sailor was again able to be up and about. And, meanwhile, Sir Reginald and Colonel Sziszkinski continued the examination of the wreck, but unfortunately without any satisfactory result; for although they succeeded in finding the captain's cabin, and bringing therefrom, and from some of the other cabins, a considerable number of documents, it was found that, owing to their long submersion, they had become so completely sodden that any attempt to handle them, while still wet, reduced them to pulp; and when the alternative of carefully drying them was tried, they became so exceedingly brittle that they simply crumbled to pieces, while, even on the fragments that they contrived to preserve, the writing was so nearly obliterated as to be quite undecipherable. Nevertheless, they preserved as much as they could, in the hope that the experts in such matters, at home, might be more successful than themselves. But it may here be stated that the experts also failed; and the name and nationality of the ship, as well as the identity of those who perished in her at the murderous hands of the savage M'Bongwele, remain a mystery to this day. On the third day following Mildmay's adventure with the octopus, the _Flying Fish_ being once more berthed on the beach near the spot where the party had made their amazingly rich haul of rubies, all hands had adjourned to the deck after dinner to enjoy the delicious coolness of a breeze off the sea. Ida had gone to bed somewhat earlier than usual that evening, complaining that she was not feeling very well, her symptoms being a feverish pulse and a slightly increased temperature, toward the alleviation of which the professor had administered a fairly liberal dose of quinine. Sir Reginald and Lady Olivia, naturally anxious in everything relating to their only child's health, were discussing the matter with von Schalckenberg, who was endeavouring, without his usual success, to reassure the pair, who were of opinion that the African climate was to blame for their daughter's indisposition.
