statement of the analyses of nine of the N.Z. black sands is given, from which it appears that the Taranaki ironsand contains no less than 56 per cent, of metallic iron.

A very large proportion; whilst the percentage of titanium is very appreciable, being about 1.5 per cent. Whether this quantity is suiEcient to produce all the wonderful effects attributed to it is doubtful. It is certain that remarkably good steel is produced from the ironsand alone, and the only question is, whether it can be economically produced in this country, which will depend chiefly on the supply of fuel obtainable near those places where the sand is found.
It cannot be doubted that the freight saved would yield a very handsome profit to the manufacturer, and enable him to compete with the European ironmaster here, even if he should not be able to undersell him in his own country.
Third Meeting. 28th July, 1868.
J. C. Crawford, F.G.S., in the chair.
The Chairman explained that, during the session, a series of addresses on subjects of interest would be delivered, under the auspices of the Governors of the New Zealand Institute; and that a course of four lectures on the geology of New Zealand would be delivered by Dr. Hector.
The Chairman also informed the members that since their last meeting steps had been taken to incorporate their Society with the New Zealand Institute, and that a favourable reply had been received. He then explained the privileges they would enjoy as members of the Institute, and the rules to which they became subject. He urged the members to enter into an honourable rivalry with the other local institutions in the colony, and to show that they were not to be surpassed in the excellence of their papers and lectures on matters of scientific interest. It was especially desirable that all classes should be enlisted in the interests of science, because a careful observance of facts in different quarters would, if properly reported to the Society, be of great value. Several gentlemen in other provinces had subscribed to their Society, but as they now possessed local institutions of a similar character, it was considered unfair to call upon them to contribute, and it had therefore been proposed to refund their subscriptions.
