SIR HENRY HOLLAND, Bart., M.D.,

F.R.S., D.C.L., ETC. ETC.

My dear Sir Henry,

In giving myself the pleasure to dedicate, as I now do, this work to you, it is not my intention to identify you with any views of my own advocated in it.

I simply avail myself of an opportunity of paying a tribute of esteem and regard to my earliest scientific friend—the first to encourage me in pursuing the study of nature.

I remain,

My dear Sir Henry,

Ever faithfully yours,

ST. GEORGE MIVART.

7, North Bank, Regent's Park,
