Cholera in Relation to Certain Physical Phenomena. [part i. 



IV.— GENERAL CONCLUSIONS. 



CHAPTER I. 



A COMPARISON OF THE PRINCIPAL PHYSICAL CONDITIONS CHARACTERISING THE VARIOUS 

 SEASONS OF CHOLERA-PREVALENCE IN THE ENDEMIC AND NON-ENDEMIC AREAS. 



Having previously considered the physical features of the various seasons of cholera- 

 prevalence in those parts of the Bengal Presidency in which the disease is endemic 

 and in those in which its occurrence is occasional only, it remains to be seen how 

 far any community of conditions characterises the seasons throughout both areas, 

 how far prevalence appears to be favoured or repressed by definite conditions inde- 

 pendent of mere geographical position of locality. 



The following table shows the conditions presented by two typical stations, 

 Calcutta and Lahore, which may be regarded as presenting extreme examples of the 

 characteristics of the endemic and non-endemic areas, both in regard to physical 

 features and cholera-prevalence.
