THE WEATHER, INFLUENZA, AND DISEASE. 601 



trasting these figures with those for the corresponding epidemic period, the differences 

 become much more accentuated. For instance, the total admissions were 7 '5 p.c. up in 

 the one, 7*5 p.c. down in the other, the corresponding figures for the Eespiratory system 

 being 21*1 p.c. and 19*3 p.c, for Pneumonia 5*3 p.c. and 27 p.c, Pleurisy 47 p.c and 

 2*9 p.c, the Nervous system 16 "2 p.c. and 17*0 p.c, and for the mortality 9*9 p.c. and 

 7 '4 p.c. The after-effects of this epidemic of Influenza were therefore very slight. 



A study of the figures for the 16 weeks after the great epidemic of 1891-92 shows 

 that they correspond very closely to those already given, the only points worthy of 

 mention being that cases of Pneumonia still remained more numerous than usual, the 

 Heart cases were much above the normal, while the Nervous cases were practically 

 normal. Contrasting them with the figures for the epidemic period we find the follow- 

 ing : — the total admissions were 5 p.c. above the mean during, and 1'2 p.c. below after, 

 the epidemic, the Eespiratory cases 29 '2 p.c. and 21*2 p.c, Circulatory 9 "9 p.c. and 127 

 p.c, and Nervous 13'1 and 15 p.c, the mortality 9*6 p.c. during, and 10*1 p.c. after. 

 The Circulatory system seems, therefore, to have suffered the most in this instance. 



The Circulatory and Nervous systems were most affected after the next epidemic also, 

 the other figures calling for little notice. Comparing them as before with the figures 

 for the epidemic weeks, the usual differences are well brought out again. The total 

 admissions were below the normal during each period ; the Eespiratory cases 25 '2 p.c. and 

 17*4 p.c, Pneumonia 6'5 p.c and 3*89 p.c, Pleurisy 3*2 p.c. and 2*0 p.c, Circulatory 

 cases 9*4 p.c. and 12*1 p.c, Nervous cases 14*2 p.c. and 18*9 p.c, while the mortality 

 was slightly below the mean in both periods. The epidemic of 1893 was followed, 

 therefore, by an increase in Cardiac and Nervous affections, the latter very markedly. 



The outbreak of 1893-94 is peculiar in that the total admissions during the epidemic 

 were below the average for the year, and for the period after the attack above it, the 

 figures being 96*2 p.c. and 101*4 p.c. respectively. The figures for the different classes 

 of disease do not present much variation from those of the other post-epidemic periods, 

 both the Circulatory and Nervous systems again showing an increased number of ad- 

 missions. 



The last epidemic, that of 1895, was followed by the same conditions, except that 

 the Circulatory system did not suffer much, while the death-rate kept up above the 

 normal. Perhaps the most striking point was the difference between the numbers of 

 Nervous cases admitted during and after the epidemic : 10'7 p.c to the total admissions 

 during, they rose to 15*9 p.c. after the attack ; or, to put it in a different way, the in- 

 crease in the actual numbers after the outbreak was 10 p.c, the decrease before 20*6 p.c. 



The next table (Table IX.) shows the same figures considered in bulk, — that is, for 

 the total period in which Influenza was epidemic, or 68 weeks, and for the 92 weeks 

 which followed them, beginning 4 weeks after the close of the epidemics. The means 

 taken, with which the numbers were compared, are for the seven years from October 1888 

 to October 1895. The total admissions of all cases into the Medical Wards were 3 p.c 

 above the mean during the epidemic periods, 0*6 p.c. above it for the succeeding weeks.
