dicularly under the object : then the body being put 
in an oblique fituation, more or lefs in this manner, 
and the mouth and eyes being near the furface 
of the water, the Jaculator flays a moment quite im- 
moveable, having its eyes diredtly fixed on the infedt, 
and then begins to fhoot, without ever fhewing its 
mouth above the furface of the water, out of which 
the fingle drop, fhot at the objedt, feems to rife. 
With the clofeft attention I never could fee any 
part of the mouth out of water, though I have very 
often feen the Jaculator fifii fhoot a great many drops 
one after another, without leaving its place and fixed 
fituation. 
No more than two different fpecies of this fifh are 
found here. 
The firfl and rarefl kind is that which I fent before ; 
and to the defcription publifhed in the LIVth volume 
of the Philofophical Tranfadtions, the foregoing ac- 
count may be added. You now will receive from me, 
a fpecimen of the fecond fpecies, which is the mod 
common here.
