Ten samples of Ice Cream were taken for analysis, the results being given below:—
BACTERIOLOGICAL ANALYSIS OF ICE CREAM SAMPLES.
| Date. | Total Bacteria per c.c. | Bacillus Coli absent in | Remarks. |
|---|---|---|---|
| 7.7.32 | 55,000 | 0.001 c.c. | Satisfactory bacterial purity. |
| " | 140,000 | 0.0001 c.c. | Not dirty but does not attain standard which can reasonably be obtained. |
| " | 46,000 | 0.1 c.c. | Satisfactory bacterial purity. |
| " | 3,600 | 1 c.c. | Highest standard of bacterial purity and cleanliness. |
| " | 310,000 | 0.000001 c.c. | Unsatisfactory and does not attain standard which can reasonably be obtained. |
| " | 280,000 | 0.00001 c.c. | Low grade of bacterial purity. |
| 14.7.32 | l10 ,000 | 0.0001 c.c. | |
| " | 320,000 | 0.00001 c.c. | Unsatisfactory sample. Considerably below standard of a high grade product. |
| " | 160,000 | 0.0001 c.c. | Low grade of bacterial purity. Does not quite attain standard which can readily be obtained. |
| " | 80,000 | 0.001 c.c. | Satisfactory bacterial purity. Clean product. |

Biological Examination of Milk Samples.
The County Medical Officer states that samples of milk were
taken in the Borough by the County Food and Drugs Inspector and
