pumice was of great age, as it must have been deposited by the rivers when they ran at a much greater height than at present. Mr. Crawford did not prove by his paper that the sea had not been relatively lower, or, in other words, that the land had not been undergoing submergence. The sea could never have been at a much higher level, or the pumice would have been drifted up, but there is every reason to believe that the country was much higher formerly, and, in the interior, contained larger lakes by which the pumice would be drifted up at great heights above the sea.
Mr. Hart thought that indications of sea level, by deposits of pumice, could not be relied upon as a measure of time, and instanced cases of sudden elevations or depressions in this province.
Mr. Travers said there were other indications of an alteration in the elevation of the coast line; for instance, the raised sea beach on the Hutt road.
On the motion of Mr. Mantell, the discussion of Mr. Crawford's paper was deferred until the first meeting after it should have been printed.
3. "On Hybridization with reference to Variation in Plants," by W. T. L. Travers, F.L.S. (Transactions, p. 31.)
Dr. Hector remarked that it was highly satisfactory that a gentleman who was a member of that Society had, by close observation of nature in this colony, arrived at conclusions on this subject, which were almost identical with some of the views now advocated by Darwin, and he understood from Mr. Travers that the substance of his paper was communicated to Dr. Hooker, in a letter, some years ago.
4. A paper by Mr. Buchanan, botanist and draughtsman to the Museum, on "Variation in the New Zealand Flora" (reserved), was read by Dr. Hector; but as it was thought desirable to consider these two papers together, the discussion was postponed until next meeting.
Mr. Mantell suggested that the discussion would be rendered more interesting and intelligible if specimens of the plants referred to by the essayists were laid on the table.
Resolved, "That the ordinary meetings of the Society should, in future, be held at half-past seven for business, and that the reading of papers should commence at eight o'clock."
Fourth Meeting. 25th August, 1868.
W. T. L. Travers, F.L.S., in the chair.
1. Mr. Crawford read the following notes by Mr. E. Baker, "On the Appearance of a Meteor which had been recently observed by several persons in the Neighbourhood of Wellington."
