I could trace no connection between the mean temperature or rainfall and the 

 admissions of any of the classes of disease enumerated above. On the other hand, the 

 number of cases of both pneumonia and pleurisy was lower in proportion to the total 

 admissions during the later years. The percentage of nervous cases also fell a little, 

 while that of the digestive system showed indications of a slight increase. Cases both 

 of acute rheumatism and of appendicitis and perityphlitis exhibited a marked increase 

 in their numbers per cent, from the earlier to the later years. 



3. The Influence of Weather on the Admissions. 



To investigate the influence of the elements of weather on the incidence of disease, 

 the weeks of the seven years were separated into those in which the type was mainly 

 cyclonic, and into those during which the distribution of pressure was anticyclonic. In 

 some cases I had to exercise my judgment with regard to the prevailing type, — that is to 

 say, that in some instances where there were moderate gradients or small shallow local 

 secondaries, the type was determined by the weather conditions accompanying them. 

 The weeks were also divided into those in which the maximum temperature rose above 

 60° Fahr., and into those in which the thermometer did not reach that figure. The 

 direction of the prevailing wind during each week was also noted, whether it was west 

 by south, or east by north, but the results of this last item were so uniform, the 

 direction of the wind had so little effect on the admissions that I have not burdened 

 this paper with the details. The mean weekly rainfall also corresponded to the type
