Dear Sir, 
Read March io, /T Y friend Robert Long, Efq; of 
i 7 6 3- x Vjl Jamaica, favoured me with the 
drawing and defcription of a marine infedt he took 
up at fea. I believe it is a non-defcript, and as you 
have often defired me to communicate to you any 
obfervations worthy attention to prefent to the Royal 
Society, I fend you this to communicate to that 
learned body, if you deem it worthy their notice. 
I fhall always think it a pleafure to tender my re- 
fpedts in whatever I can to the Society, which pray 
allure them of. I am,, with great efteem. 
Dear Sir, 
Your very obliged friend, 
and humble fervant.
