trcmitles nafs through a calcareous cruft, and open 
into pores on the furface. The branches are often 
jointed, and always fub-divided into fmaller branches, 
which are either Joofe and unconnected, or joined, 
as if they were glued together : in Latin, thus.

This difference then will evidently appear by 
putting each kind into an acid liquor. The Coralline 
will immediately dilcover the nature of its * calca- 
reous furface, by a ftrong fermentation ; when the 
Conferva will not appear in the lqaft afteded. This 
acid liquor will likewife foon diffolve the calcareous 
fubflance in the Coralline, by which means the mi- 
nute velfels that lead to the pores on the furface will 
become vifible ; whereas the Conferva will unal- 
terably remain the fame, and be rather preferred 
than corroded by the acid. 
When Dodor Pallas, who fupports the opinion of 
Dodor Balder, comes to the chemical analyfis of the 
Corallines, he tells us ft that he had not time nor 
opportunity to try them ; but depends on the report 
of other authors.
