    {The Chairman.) Perhaps you will be able to let us have these relations definitely ?—Certainly. {Dr. Irvine.) With regard to these analyses of samples, there were 21 analyses of samples taken on the night of the 14th September in three supplementary huts at the Gleen Deep. Now when we made up that summary at the end we suggested a classification of experimental huts, ordinary huts, and miscellaneous huts, which had not been supervised by Dr. Moir and were not, therefore, not official evidence. Now these series of analyses were really selected huts, and I would like to ask Mr. Williams to go over them. The confusion has arisen from our not having adopted a nomenclature from the start. There is another little alteration I would make in one of the tables. In considering chart (3), the 13 selected mines, you will notice that the black line means the level of the 100 per cent, replacement, but several of the mines did not replace their com- plements to the extent of 100 per cent., and, therefore, in order to give this chart its full value, the difference between these two black lines should be added together. Table F. 4, gives the percentage locally engaged and the percentage remaining on the mines. {Mr. Williams.) Might I explain the question Dr. Irvine has raised as to the samples taken of the three experimental huts on the Glen Deep. They were experimental in as much as they were slightly modified, because we had altered the partitions between the two rooms and we had storm doors put in, but the term experimental was only used because they were slightly different to the huts used on the mines. I think I already drew your attention to that. {Dr. Irvine.) My point is this. In your summary you reserve the term “ experimental huts ” for the Medical Society’s huts solely and, therefore, con- fusion arises. They are not experimental huts in that sense. They are specially selected mine huts. {The Chairman.) Before you go, Mr. Williams, have you put in these plans officially ?—I thought I should like to give you copies of the whole of them. Are they put in officially ?•—Yes, Sir. Minutes of Evidence. Mr. J. R. Williams. 24 Sep., 1904. The'public sitting of the Commission thereafter concluded.
