30. Having done with the Inventions and Improvements that 
concern the Heavens^ come we next to thofe belonging to the fuh^ 
lunary Worlds whereof the fame Ingenious Sir C hriftof her Wren 
has furnifh'd us with feveral ; as of exquifite fubtilty, fo of ex- 
celleatufe: Such as his contrivance to make Diaries of wind and 
weather^ and of the various qualifications of the ^/V, zsioheats^ \ 
colds ^drought, moifture, and weighty through the whole je^^r ; and I 
this in order to the //i/^orjc/ Seafons : with obfervation, which 
are.the moft healthful or contagious to men or bea/is • which, the | 
Harbingers of blights^ meldews^fmut^ or any other accidents at- 
tending men^ cattle^ o'c grain ; fo that at length being inftrufted in 
the caufes of thefe evils^ we may the eafier prevent^ or find rejne- 
dies for them . 
3 1 . Now that a conftant obfervation of thefe qualities of the 
air^ both by night and day might not be infuperable ; he contri- 
ved a Thermometer to be its own Regijier^ and a Clockto be annex- 
ed to a weather-cock-) which moves a Rundle covered with white 
Paper ; upon which the Clock, moving a black-lead the oh- 
ferver^ by the traces of the penfil on the paper, may certainly I 
know what TP/W^ have blown, during his flcep or abfence, for 12 
hours together. He has alfo difcover'd many fubtile ways for 
eafier finding the degrees of drought^^nd moiffure^ and the gravi- 
ty of the AijTiofphere I and amongft other Infl:ruments, has Bal- 
lances (alfo ufeful for other purpofes) that fliew the preffure of 
the air., by their eafie (I had almoft faid fpontaneous) inclina- 
tions 
32. He has made Inftruments whereby he has fliewn the Me- 
chanical reafon of failing to all winds ; and others of Reffiration^ 
for ftraining the breath from thick vapors, in order to tryal whe- 
ther the fam,e breathxhws purified will ferve turn again. Which 
Experiments^ however nice they may fcem, yet being concerned 
about a fubjeft fo nearly related to man^ that he always lives in it, 
and cannot long without it, and is well or ill according to its al- 
terations, the minuteft difcoveries of its nature or qualifications 
ought to be valuable to us. 
33. Wherein yet we have been afTifted by nothing more, than 
the Pneumatick. Engine^ invented here at Oxon: by that niracle of 
Ingenuity, the Honorable Robert Boyle Efq; with the concurrent
