If the Dodlor will immerfe fome of thefe coral- 
lines, when they are extended, in two thirds of fpirit 
of wine and one third of clear fea-water, it will 
preferve them many years, as I have experienced. 
He may then put the different forts into diftindt 
phials, and view them at pleafure with a lens of 
about one inch and half focus. 
In fine, my Lord, opportunities fo feldom offer at 
the fea-fide to make thefe experiments with accuracy ^ 
add likewife to this, the ftrong lines of vegetation 
that thefe bodies carry in their appearance, and your 
Lordfhip will not be iurprifed, that there are fo many 
gentlemen, even of the Royal Society, that totally dis- 
believe them to be animals. 
Many there are in the Society, that are wavering 
between both opinions. If then, my Lord, yon 
think, that any fpecimens which I have, or any 
demonftrations tending to clear up this point, that 
lie in my power, will be acceptable to your Lord- 
fhip and the Society, your Lordfhip may freely com- 
mand them, whenever you think proper, from 
Your Lordsh i p’s 
Much obliged and moil obedient Servant,.
