7. I have frequently been spoken to by Medical men and Dentists as to the quality of the milk produced in this Colony. The above tables will, I trust, satisfy all those interested as to the nutritive qualities of this valuable and indispensable article of diet. The percentages quoted are the results arrived at by the Somerset House method of analysis. In every case the solids have been "dried to constant weight." I may say in one sentence that better Dairy milk could scarcely be obtained in England: the above averages compare most favourably with the results of the analyses of the best Dairy milks in Great Britain.
8. The Sanitary Board samples were collected by District Inspectors of Nuisances from retail vendors. The following are the results of the analyses:-

9. In only one case (No. 3) was I able to certify that the sample contained added water (12 per cent.). No. 5 was certainly a suspicious specimen, but I could not declare against it in view of the percentages of fat and mineral constituents. No. 7 was from the same Dairy as No. 5 and was collected at a subsequent period. The improvement in the quality of the milk after the purchase of a sample by the District Inspector is suggestive to say the least.

10. The sample of milk from the Royal Naval Hospital was found to be of normal composition.
BREAD.
11. The 3 samples of bread, forwarded by the Sanitary Board, were of good quality and very even in composition. The inorganic constituents ranged from .46 to .51, and the moisture from 41.2 to 42.6 per cent. None of the samples contained alum.
SAND,
12. Seven specimens of sand were analyzed at the request of the Director of the Public Works Department. The lime salts, chiefly carbonates, present ranged from 1.6 to 53 per cent. The finest
