Finally, I desire to acknowledge that a welcome 
donation of £100 from Mr. F. H. Gossage of Woolton 
has met the expense of preparing the plates in illustration 
of the first few Memoirs, and so has enabled the 
Committee to commence the publication of the series 
sooner than would otherwise have been possible.
