“The 1683 lots realised a grand total of £30,151, 10s., which works out at an average of as nearly as possible £18 per lot. Hitherto the highest average was obtained by the disposal in 1884 of the Syston Park library, where 2110 lots brought £28,000, or £13, 5s. per lot, the next highest average being that of the Seillière library, sold in 1887, 1140 lots realising £14,944, or about £13, 2s. per lot. It is scarcely fair, however, to compare the Ashburnham collection with either of these two libraries, as the Seillière was admittedly only the choice portion of the assemblage of the baron, whilst nearly every lot in the Syston Park library was of importance. Eliminating from the Ashburnham collection the hundreds of lots which realised less than £1 each, the average would be nearer £40 than £18.”
This is all very well in its way, but one lot fetched £4000, and such an amount would demoralise any average. Let us therefore see what are the particular points worthy of notice in the sums making up this large total of £30,151. We find that five lots realised £1000 and over each, and including these five lots, forty-two were over £100 each. Now the total for these forty-two lots is £20,348, which, if we deduct from the grand total, leaves 1641 lots for £9803, bringing our average down considerably.
This is not perhaps a quite fair system of striking an average, but it shows better how the prices of the books are distributed.
