The mass of Pyrosoma, of the usual cylindrical form and gelatinous substance, was about four inches in length and one and a half in circumference. The tube, passing along its middle, is described as being open at both ends; the orifice at the broader extremity being much better defined in its circular form, larger, and more distinct than that of the opposite end. The surface of the mass appeared to be studded with numerous prominent, rigid, and pearly tubercles intermingled with small specks of a brown or red colour. In these latter the power of emitting light appeared chiefly to be seated, these being frequently bright, while the remainder of the body exhibited only its natural white or yellowish white hue; a hue which changed after death into a red tinge. The brown specks, when removed from the body, did not emit light.[149] TREATY BETWEEN THE BRITISH AND ACHEENESE GOVERNMENTS. (_See_ page 2, vol. ii.) Treaty of friendship and alliance between the Honourable English East India Company and the kingdom of Acheen, concluded by the Honourable Sir Thomas Stamford Raffles, Knight, and Captain John Monckton Combs, agents to the governor-general, in the name and on the behalf of the Most Noble Francis Marquis of Hastings, Knight of the most noble order of the Garter, one of his Britannic Majesty’s most honourable Privy Council, Governor-general in Council of the British possessions in India, on the one part, and his highness Sri, Sultan Alla Iddeen Jowhara, Allum, Shah, king of Acheen, for himself, his heirs, and successors, on the other. In consideration of the long and uninterrupted peace, amity, and good understanding, which has subsisted between the Honourable English East India Company and his highness’s ancestors, the kings of Acheen, and in order to perpetuate and improve their friendship, to the advantage and prosperity of their mutual states and subjects. It is hereby agreed and determined. ARTICLE I.—There shall be a perpetual peace, friendship and defensive alliance, between the states, dominions, and subjects of the high contracting parties, neither of whom shall give any aid or assistance to the enemies of the other. ARTICLE II.—At the request of his highness, the British government engages to require and to use its influence to effect the removal of Syfful Allum from his highness’s territories, and the British government further engage to prohibit him or any of his family, as far as they may be subject to their authority, from doing or committing in future any act or acts, tending to prevent or impede the full re-establishment of his highness’s authority. His highness the king engaging himself to place at the disposal of the supreme government of British India, such pension or annuity, as it may, in its wisdom, deem meet to recommend for the said Syfful Allum, on the condition of his retiring to Penang, and engaging to relinquish all claims to the sovereignty of Acheen, within three months from the date hereof.
