XLIV.A Letter to the Marquiss of Rockingham, with some Observations on the Effects of Lightening.
To the most honourable the Marquiss of Rockingham.
My Lord,
Read July 28,
1764.
I Have taken the liberty of addressing the inclosed paper to your Lordship, as it contains a few observations on a subject not unknown to you, and may probably be thought of general use.
I have a further reason for addressing it to your Lordship, as it gives me an opportunity of expressing, in some small degree, the high sense of gratitude I bear your Lordship, for many and repeated favours and obligations conferred on,
My Lord,
Your Lordship's most obedient,
June 24, 1764,
Great Queen-street,
London.
and most humble servant,
LONG
