*** OBSERVATIONS ON THE BILLS OF MORTALITY AND IN- 
CREASE OF PEOPLE IN DUBLIN; THE DISTEMPERS, AIR, 
AND CLIMATE OF THIS KINGDOM; ALSO OF MEDICINES, 
PHYSIC, AND SURGEONS AND APOTHECARY S—BY DR. WIL- 
LOUGHBY, AN EMINENT PHYSICIAN, IN 1690. 
«<¢ The Bills of Mortality have not been kept in Dublin 
much above 10 years.* I have been constantly served w™ 
y™ for those 8 years last past, and thought I had a sufficient 
stock to make some observations upon, but when I came to 
: review my collection I found it very imperfect, partly by the 
neglect of servants whom I entrusted to put y™ on y’ file, and 
: partly by my own frequent absence from home; soe y‘ I was 
_ not able to make up all the yearly bills, and was fain to be 
_ content w'" those I have here entred; not knowing where to 
supply my want of y° rest in all Dublin. 
<¢* Upon the bills of Mortality and increase of people. 
<¢¢T cannot pursue a better method y" what was begun 
_ by y° learned author of this new way of observing, S*: W™ 
Petty ;{ therefore, comparing y* mortality of those 7 years, I 
have collected, I find y‘ at a middle rate y* yearly mortality of 
Dublin to be 2236,t which exceeds his middle rate, & bears 
proportion to it almost as 11 to 8, from whence we may rea- 
sonably conclude y° people of Dublin to have increast since 
y' time, almost a 3"; this was otherwise sufficiently visible 
in y® great increase of buildings, for a 3° part of ye whole 
having been erected since y* year 60 [1660] are now fill’d w® 
inhabitants as soon as finished, wout any decrease of rent. 
‘I find in y’ year 1688 y° bills of mortality sink near a 5" of 
is  * Bills of mortality for the city of Dublin were first attempted in 1661. Sir W. 
Petty has published the Bill for 1666.—See the “ Irish Census Report” for 1851, 
part v. vol. i.
