As this awful and mysteriousdisease is, unhappily, so rapidly fatal, we may safely com-pare the deaths in any week with the meteorological condi-tions of the week immediately preceding. I may state thaton the whole, a comparatively low temperature prevailedthroughout the epidemic period, and we may suppose thathad this not been so, a far greater development of choleramight have occurred, terrible as the death-rate really was. The first great mortality (41 deaths) was registered in theweek ending September 1st, a week after the mean tem-perature had attained the height of 61°, and closely following * Om Cholera-Epiilemicn i Norge i Aaret 1853 (On the Cholera-Epidemicin Norway in the year 1853 ).

But the acme of mortalitywas reached in the middle of October, after a rise of 2° inmean temperature, and a very low rainfall. The increasedmortality in the week ending October 13th is very remark-able when taken in connexion with the weather of the weekbefore, which was continuously calm, cloudy, foggy, dmnp,ivith a very high harometer, and a great deficiency of ozone(the latter showing a mean value of only 10 per cent, at theOrdnance Survey Office, Phoenix Park). The decrease in the mortality was consequent on a freshen-ing and a change of wind from to , a diminution ofbarometrical pressure, a moderate and continued ra
