Thus the curves of mortality from whooping-cough, typhoid fever, and
scarlet fever do not correspond with the curves of temperature in both
London and New York, and the same may be said of diarrhoea in India. It is
therefore evident that some other cause or causes than a varying
temperature must be concerned in the production of an increased death-rate
from these diseases. The subject is of great importance, and I do not
despair of our obtaining some day a knowledge of the agents through which
meteorological phenomena act in the production of increased and decreased
death rates from certain diseases, and the means by which, to a certain
extent, these injurious effects on man may be presented.

P. Rosenbach has found experimentally that potassium bromide diminishes
the sensibility of the cortical substance of the cerebrum to electric
excitement, while, the excitability of the underlying white substance
remains unaltered.
