will afford others differing from the former, while the succeeding one shall produce some other sorts that were not to be seen before; so that by searching for them at different times, you perceive great varieties will be collected. I must also beg you to preserve the horns of them as much as possible, as they in a great measure determine their genus, and as such should not be broke off. The insects placed in the box will serve as samples to show the person you may hire what kinds of things are meant to be collected, who for want of them might not be able to understand your instructions. I have now, Sir, mentioned every article necessary to be known, therefore shall conclude with once more begging you to assist me in this scheme; and if there is any business, or any other thing, in which I can be serviceable to you here, I beg you would command me; but if there is nothing of that kind by which I can express my gratitude, permit me again to repeat I shall take the first opportunity of making a return fully adequate to your favour. I am, Sir, with great respect, your most obedient servant, D. DRURY, At No. 1. in Love Lane, Aldermanbury, London. P. S. I forgot to mention that when you employ an agent to collect insects, please to tell him it is not the great number but the variety that I desire, six or eight being enough of any one species. Subsequently, this fine collection came to the hammer, on Thursday, May 23, 1805, and the two following days. A few of the more interesting lots, with the prices obtained for them, and the names of the purchasers, are given below as an interesting record.
