SAMPLES COLLECTED AT RAILWAY STATIONS.
In accordance with the practice which was instituted many years ago, a further series
of milk samples arriving in the City from country districts was obtained at Liverpool Street

The samples were sent to Sir Frederick Andrewes, K.B.E., the City Bacteriologist,
for bacteriological examination and investigation as to the presence of dirt, and a duplicate
of each sample was also submitted to Mr. E. A. Pinchin, B.Sc., the Public Analyst, for chemical

farms in the following counties:—
Suffolk 15
