348 DR R. E. SCORESBY-JACKSON ON THE INFLUENCE OF WEATHER, ETC. 



The foregoing table — 



1. Suggests a direct relationship between the rainfall and the death-rate from 

 all causes in winter and spring; but an inverse relationship in summer and 

 autumn, — a suggestion which the previous results tend to support. 



2. Suggests a direct relationship between the rainfall and the death-rate from 

 zymotic diseases in winter, spring, and autumn ; but an inverse relationship in 

 summer. This suggestion also is nearly supported by the previous results. 



8. Shows that there is a slight indication of an inverse relationship between 

 the rainfall and mortality from phthisis in winter, spring, and autumn ; but of a 

 direct relationship in summer. These indications, however, are not very distinct, 

 and are not well substantiated by the previous results. 



4. Indicates a direct relationship between the death-rate from bronchitis and 

 the rainfall in spring, summer, and autumn ; but an inverse relationship in 

 winter. This is not distinctly observable in the previous results ; and probably 

 the note appended to the fifth suggestion, under bronchitis, is the true explanation 

 of the inconstancy of the relationship, 



5. Shows that the influence of the rainfall upon the death-rate from all causes 

 varies with the periods of life. In infancy the relationship appears to be direct 

 in winter and spring, doubtful in autumn, and inverse in summer. At other 

 periods of life the relationship is scarcely perceptible. 



Here I must close my paper. I offer it as a slight contribution to medical 

 climatology, and I trust there will be found in it something worthy of the con- 

 sideration of those who take an interest in that still very obscure science. The 

 interpretations that I have given of the facts at my disposal are such as I think 

 they will bear without straining ; but I place both facts and comments before the 

 Society, so that any one who is interested in the matter may judge for himself
