I considered first, that I had not yet obtained information sufficient on the subject to qualify me for the undertaking of such a work.

But I reflected, on the other hand, that Sir Charles Middleton had just opened to me a new source of knowledge; that I should be backed by the local information of Dillwyn and Ramsay; and that surely, by taking pains, I could acquire more.
I then considered that I had not yet a sufficient number of friends to support me.

This occasioned me to review them.

I had now Sir Charles Middleton, who was in the House of Commons.

I was sure of Dr.Porteus, who was in the House of Lords.
