A sample of milk was procured from each workhouse by Mr Rowsell at two different dates, and forwarded to me for analysis. The analysis of the earlier sample is marked I. in the following table, and that of the later sample is marked II. Samples were also forwarded to Dr Letheby, who arrived at the same general results as myself; but either from his hav- ing slightly different specimens, or from employing different methods of analysis, his numbers sometimes exhibited some considerable departures from my own. There was, however, no difference in the practical effect of the two reports. On inspecting the table, it will be seen the milk from twenty-eight Unions is reported upon. A well-known metro- politan Union is conspicuous by its absence, and the report would not be complete unless it were recorded that the West- minster Union refused to furnish Mr Rowsell with informa- tion and samples.
