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.
