constantly above the average. On referring to the details of group ITII., it will be 
found that these peculiar results are due wholly to the deaths from phthisis, and there= 
fore the preceding observations are strictly applicable to that disease only. 
Group IV. contains the diseases of the nervous system, and it will be seen that the 
results do not differ widely from those for all catises; and the same remark applies 
to the deaths from apoplexy, which form a large proportion of this section. 
On referring to group VI., which represents the other diseases of the lungs and the 
organs of respiration, it will be seen that, with the exception of the decennial term of 
life, 55-64, the deaths take place in a shorter time after the date of assuring than in 
the ayerage of the deaths from all causes, and in the aggregate of all the ages the 
difference is six months. These restilts are due chiefly to the deaths from pneumonia, 
which constitute 229 out of the 251 deaths of this group. And it will further be 
seen, that the deaths from asthma have taken place at a prolonged period beyond the 
average. : 
In Fepard to the diseases enumerated in group VIJ., it will be found that, on the 
average, they agree in their results with the deaths from all causes; and that in the 
different quinquennial terms of life the results are in some instances above, and in 
others below the average. 
If attention be now directed to the rate of mortality from the various specified 
causes given in Table VI., it will be found that, for all ages taken collectively, the 
greatest mortality has resulted from zymotic diseases, or those forming group I.; and 
next, tubercular diseases, or group {Π1., which are here separated from the other 
diseases of the lungs and organs of respiration, which form a distinct class in group 
VI. The rate of mortality from the zymotic diseases does not differ widely between 
ages 31-50, but from that age upwards a rapid and uniform rate of increase takes 
place: in group II., including dropsy, cancer, &., there is a uniform rate of in- 
crease from the younger to the older ages. In the class of tubercular diséases, there 
is not much difference in the rate of mortality from between ages 31-50; but in the 
next three quinquennial terms of life there is a gradual increase. In group IV. there 
will be observed a very great difference between the rate of mortality at the younger 
and more advanced ages; of the 375 deaths in this group, 274 consist of deaths from 
apoplexy. ‘The results of group VI. resemble in their relation those in connexion 
with group III. Group VIL., it will be observed, resembles the results of group IV. 
in having a very low rate of mortality at the earlier ages, and increasing rapidly at 
the more advanced terms of life. 
The preceding remarks have been made on six only of the principal groups of dis- 
eases, and the following condensed abstract of the results may be interesting. The 
Roman numerals represent the diseases as grouped in the preceding table. 
Diseases arranged according to the Order of their Intensity at the following Ages. 
31—35. 36—40. 41—45. 46—50. 51—55. 56—60. 61—65. 66—70. 70—80.

Τὴ the above, it will be seen that, at the earlier ages, the intensity of the zymotic 
diseases, and also tubercular disease, is greatest ; but at the more advanced, a gradual 
falling off will be observable in the class of tubercular disease. In the term of life 
56-65, tubercular disease stands fourth in the order of intensity, and in the term 
66-890, last in order. Again, with respect to Class 1V., which consists, to a great ex- 
tent, of deaths from apoplexy, it will be observed that, in the period of life 36-50, it 
stands fourth in the order of intensity ; but that in each of the three succeeding quin- 
quennial terms of life it gradually advances one step in the order of intensity, until, 
at the term 66-70, it is highest in intensity. This assimilates strictly with preceding 
results, however, with regard to the class pulmonary diseases, or diseases of the 
respiratory organs; that not only, in the abstracts just referred to, and in the earlier 
reports of the Registrar-General, included in group III., but also group IV.; and if 
the results be viewed in accordance with this arrangement, the diseases of the re-
