Dear Sir, 
Promifed you, in my letter of the 
7th of February 1754, publidied in 
our Tranfadtions, Vol. xlviii. p. 507. that I would, 
when I had an opportunity, endeavour to illudrate 
the tubular drudture of the common red coral of the 
Mediterranean fea, and of fome of the keratophyta , 
which two kinds, tho’ evidently of as different na- 
tures as done and horn, yet are, from late obferva- 
tion, found to be faddoned, or raifed up into thofe 
beautiful forms, by animals of the fame clafs. 
This I fhall attempt to do, by comparing them 
with bodies of a dmilar kind, but of a lefs compadt 
texture : for which reafon I formerly referred you, 
in the above-mentioned letter, to a figure, which I 
have given of the herring-bone-coralline, with its 
animals
