XXXIII. Remarks on Dr. Job Baster's Observationes de Corallinis, &c. printed above, p. 258. In a Letter to the Right Honourable George Earl of Macclesfield, President of the R. S. from Mr. John Ellis, F.R.S.

My Lord,

Read June 9, 1757.

I Have read Dr. Job Baster's letter to the Royal Society; wherein he endeavours to prove, that corallines are not of an animal, but a vegetable nature; and has brought many arguments to support his system; which, to gentlemen not well acquainted with the subject, may appear plausible.

I could have wished the Doctor had read and examined thoroughly what has been lately written on the subject: I then should not have had occasion to trouble your Lordship with the following remarks, which I find necessary to support what I have already advanced on that head.

His first argument is, That because he does not find as many polypes in the corallines adhering to ships, flood-gates, and buoys, as in deep water on oysters, muscles, and rocks, therefore he concludes, that corallines are not formed by polypes.
