sanitary movements have overshadowed — viz. “ The special 
influence of occupation.” 
In this abstract, to simplify as much as possible, the town 
population is divided into groups : one-fifth consists of certain 
occupations not peculiar to towns, but common to the present 
state of society, viz., out-door heavy occupations. This class 
is amenable to the worst influence of town life, and Avithout 
the advantage of high Avages and consequent choice of abode 
and addenda to the necessities of life — its mortality in tOAvns 
is yet only 17’5 in the 1 , 000 , the loAvest mortality of the 
kingdom being 15 in the 1 , 000 . The other four-fifths consists 
mainly of the skilled operative and commercial and profes- 
sional classes. The mortality of this section is caused by the 
skilled Avorkers, and mostly so when constrained position is 
requisite. One main object of the paper is to draw attention 
to this special element of tOAvn mortality, the alteration in 
the normal proportion of respiration to circulation of the 
blood appearing to be the turning point from health to disease. 
This portion of the subject cannot be entered into without 
considerable detail, given in the Paper itself. One point 
appears to be prominent, viz., that in the endeavour to venti- 
late, cleanse, drain, and distribute our tOAvn population, the 
necessary employment to earn a livelihood in towns has carried 
Avith it the seeds of disease and death, and escaped to a great 
extent the notice of those able and philanthropic people Avho 
have devoted their energies to the best mode of increasing 
the health and prosperity of their fellow-labourers.
