X. An answer to the objections stated by M. De la Lande, in the memoirs of the French Academy for the Year 1776, against the solar spots being excavations in the luminous matter of the sun, together with a short examination of the views entertained by him upon that subject

Dear Sir, Having lately seen a paper on the Solar Spots by M. de la lande, in the French Memoires for 1776, published in 1779, I found such mention made of mine upon that subject, as appears to me to require an answer; not only in justice to myself, but to that honourable Society who admitted an account of my discovery into their Transactions, and to philosophy in general, whose cause it becomes a duty upon her followers to vindicate from such errors as seem likely to prevail.
