[7] "This Morning, 5th September, I Let Down A Thermometer, Suspended
In The Middle Of A Strong Wooden Case, Of Such A Construction As To
Let The Water Pass Freely Through It In Its Descent, But Which Shut
Close The Instant It Began To Be Drawn Up.
By this means the
thermometer was brought up in a body of water of the same heat with
that it had been let down to.
The results were as above." - W.
This opportunity may be used for introducing the following table and
remarks, which are certainly deserving attention. "To ascertain the
degree of warmth of the sea-water, at a certain depth, several
experiments were made by us. The thermometer made use of, was of
Fahrenheit's construction, made by Mr Ramsden, and furnished with an
ivory scale; it was, on these occasions, always put into a cylindrical
tin case, which had at each end a valve, admitting the water as long
as the instrument was going down, and shutting while it was hauling up
again. The annexed table will at once shew the result of the
experiments.
