I have had an opportunity lately of examining 
this curious, flefhy, coral-like figure in the micro - 
fcope, and find, that all the interfaces between the 
ftars are fill’d with egg’s of different fizes, each ad- 
hering by one end to a very fine capillary filament. 
The fmalleft eggs are globular, and as they advance 
in fize, change to an oval figure ; from thence they 
afiume the fhape of one of the radii of the ftars. 
In feveral of thefe ftars I have obferved a fmaller 
radius, as it were, endeavouring to get into the cir- 
cle ; and notwithftanding their feeming connection 
in the center as one animal, I believe I fliall foon be 
able to fhewyou, in a drawing from the microfcope, 
that each radius is a dilfinCt animal by itfelf. I am,
