Parliament for the county of Cornwall. In this letter he recapitulates what had been done towards the topography of his native county. Besides the works of Leland, Camden, Norden, and Carew, he mentions the general collections of Hals and Anstis, and those of Pearce and Gwavas on the Stannaries, the Cornish language, etc. Towards the conclusion of his epistle, he says, 'I wish I could say that many more of my countrymen had assisted me with their kind endeavours. I do not yet despair of having several; for which reasons I have, in my proposals, enlarged the designed time of the publication of this part. I hope they will be so good as to send in contributions. If they persist in their refusal, they must be contented with such coarse fare as I am able to give them, which I will endeavour to make as palatable for them as I can; perhaps, when they come to taste of this, they may be prevailed on to supply me with something better towards the two remaining parts. All that I can promise them is, that I will give them the best account I can, without the least partiality; neither shall any one person have a just occasion given him to charge me with any wilful omission or sophisticated truth."
Very little was done by Mr. Tonkin to the parochial department of his intended history after the date of this letter; he died in 1742, and in the latter part of his life, being unhappily involved in pecuniary difficulties, he grew less attentive to study, and died without printing any part of his intended history.
