vi PREFACE. 
the growth of oak galls, and one purpose of the 
following pages will have been accomplished if they 
are the means of inspiring somebody to further unfold 
the subject. 
I shall esteem it a pleasure to endeavour to identify 
any galls. Specimens should always be sent in a tin 
bow. 
I desire to acknowledge with much gratitude the 
kindness and help received from my aged friend, the 
Rev. E. N. Bloomfield, M.A., F.E.S., of Guestling Rec- 
tory, Sussex, without whose stimulation and encourage- 
ment I should probably never have studied galls. 
To Mrs. M. J. M. Andresen of Hastings, I offer my 
heartiest thanks for translating various Continental 
treatises ; and to my wife, for valuable assistance from 
the earliest contemplation of the work, and with the 
proof-sheets; to Sir Archibald Lamb, Bart., for his 
kindness in allowing me, at any time, to roam about in 
Beauport Park in search of specimens; to Dr. Alfred 
Nalepa of Vienna, for permission to reproduce Plate 
LXIV; to Mr. W. H. Hammond for the photo-micro- 
graphs divs. B and OC, Plate XXXII; to Mr. A. W. 
Bawtree, F.L.S., for the insets on Plates XLVIII and 
XLIX; also to Mr. H. Stone, F.L.S., F.R.C.1., and 
Messrs. W. Rider and Son, Ltd., for permission to 
include Plate II; to Mr. E. W. Swanton, M.C.S., for 
specimens and notes of observations; and also to Mr. 
W. W. Midgley for a valuable specimen.
