Tranflated from the French. He Writes thus : 
* There are found on the Coafts of Malabar and Cey- 
i Ion, certain Cockles or Shells in Dutch called Keuk-horens. 
\ Thefe Shells contain a Filh that lives in the bottom of 
* the Sea , fixt to the Body of the Shell, and at a certain 
4 Seafon of the Year, they call: their Seed which produ- 
ces a fort of Matrix of the fize of the Figure*; this Vid.E*. 
'long Body which is wrinckled like an AndouiUe erSauf 4, 
'age is filled with a great number of round Celles, which 
' are fo many Matrices^ each producing its little fhell- 
< fifh ; which quit not their cells till they are grown to 
<(uch a bignefs and maturity, as their weight breaks them 
'off and loofens them from their cells, and fo from their 
€ common Matrix, which remains faftoed to the bottom 
' of the Sea by the great end, the other end moving a- 
* bout freely in the water, which is flexible every way 
1 like an Andouille. This Matrix the Hollanders call 
i Swambalk. 
' It is ob fervable that this Matrix has a kind of back- 
< part and Belly, the Back is fomething like that of a 
4 Sckelvis and of a greyifli colour, the Belly is whiter, 
* and is that part which is filled with the cells from one 
< end to the other : the Skin which covers it is very like 
* that of Stock* flfti or other dryed Fifli. 
' Figure the $th, Is a lhell found in the River of Goa, 
i which holds a fort of Oyfter. It is very fcarce and 
* in the Indies as well as here the fliell powdered is efteem- 
' ed a good Medicine.
