Unidentified Material.

In Table III we give a summary of the analyses of one paua, so far as our analyses were carried. The results show a deficit which is very large in the case of the visceral part. Some of this is no doubt due to the glucose and to remains of vegetable food in the alimentary tract, but these cannot account for more than a small part of the large deficit. The large percentage of material soluble in alcohol in the following sample also indicates the unusual nature of this food: Paua 4 solids, 23.1 per cent. Of the solids, 8.14 per cent. = fat, 7.5 per cent. = ash, and approximately 28 per cent. was soluble in 96 per cent. alcohol, but insoluble in ether.
