the written account of all he was De
sired to bring in the next Day.
m
r. Hooke propo
sed the following Exp
t. to be made the next meeting. viz
t, to shew the Difference in the refraction of warm
water and cold
and to the Difference in the weight of warm water & cold 3
ly. the Liuing of In
sects in Conden

To which he added a sugge
stion concerning the Rectifying of chimneys or the ways of ordering the Combustible mate

r. Hooke made 2 of
the Exp

sd by him the
Last precedent meeting v
t. that of the Dif

In
sects in Conden

t. concerning the Differing
weight of /2/ warm & cold water both were orderd to be entred.
m
r. Hooke made

ththe hypothesis It was orderd to by repeated next Day

Exp

whether holds exactly by 20 40 60. 80. or not) M
