Waipori.

This sample of Cinnabar, forwarded by Mr. R. Gillies, was was obtained from Waipori. It yielded 76 per cent. of metallic mercury.

Another sample was forwarded from Waipori, or Waitahuna, by Mr. Rutherford, and was found to contain 72 per cent. of metallic mercury,

Both these ores, if they exist in quantity, are very valuable. The metal is easily freed, by means of cheap fuel (dried scrub, &c.) and lime from the sulphur with which the mercury is contained in cinnabar. The extensive use of mercury in this Colony and in Victoria for the extraction of gold is an additional reason for not neglecting any ore of that metal that exists in the country.

Waitahuna.

A sample forwarded from Waitahuna, by Mr. R. Smith, contains from 70 to 75 per cent. of mercury, and is therefore very valuable.

Carrick Range.

This sample was forwarded by Mr. W. Buchan, from Carrick. It is the best sample of cinnabar yet analysed in the laboratory. It contains 82 per cent. of the metal. This ore is of great value if present in quantity.
