specially-protected workers into rat-protected stands. When a case of human plague has occurred on board, the clothes and bedding are sterilised and the water used during this process is boiled before it is allowed to flow into the Elbe.
On the fifteen ships first submitted to this process, 2845 rats were killed, of which 150, or 5.2 per cent., were plague infected; in the same ships 184 mice were killed, of which only one was proved to have plague.
It would have been impossible for me to have profited so much by my two days' stay at Hamburg if it had not been for the great courtesy of Dr. Fulleborn, who most kindly devoted some hours to explaining the methods of work to two or three of us.
I have, I hope, shown that the Hamburg Tropical School is full of vitality, and doing excellent work. Enjoying, as it does, liberal financial support from the Government, it is already in a more favourable position than the Tropical Schools of London and Liverpool, and England must look to it that she be not left behind in the friendly competition for increased knowledge in the vital subjects of tropical medicine and hygiene.
