    fever lias recently been shown by Dr. Bell, of St. Andrews, to have been conveyed by milk to the customers of a cowkeeper in that place, the cows having been milked by persons convales¬ cent from the disease. I claim now to have shown, what I have long suspected to be probable, that typhoid fever may be similarly conveyed by milk. Whether I have also correctly referred the contamination of the milk in this case to its source in contaminated water, others are better judges than myself. At all events, I have spared myself no labour in the investiga¬ tion, which, if it has resulted in nothing else, has demonstrated one of the dangers connected with the mode in which the trade in milk is conducted in this metropolis.
