It may be stated that although railway journeys in Spain 
are slow, yet the five minutes at each station gives an oppor¬ 
tunity for picking up many plants which would otherwise be 
overlooked. The buffets on the Andalusian and Catalonian 
lines are fairly good and reasonable, but travellers from 
Seville northwards to Bayonne had better provide themselves 
with refreshments for their journey. For guide books, 
Murray’s is certainly the best. For botany, the “Flora His- 
panica,” by Wilkomm and Lange, is a capital book. Kel- 
aart’s “ Flora Calpensis ” is useful, as is also Boissier’s 
“Voyage d’Espagne.” Colmeiro’s “ Enumeracion ” gives a 
good idea of plant distribution through the Peninsula, and 
various isolated papers by Joseph Woods and Bentham are 
also recommended.

A book, in which the readers of the “ Midland Naturalist ” 
will feel much interest, has just been published by Messrs. 
Bickers and Son, London. Its title is, “ Induction and 
Deduction : a historical and critical sketch of successive 
philosophical conceptions respecting the relations between 
Inductive and Deductive Thought, and other Essays,” by 
Constance C. W. Naden ; edited by R. Lewins, M.D., Army 
Medical Department. “Induction and Deduction ” occupies 
the larger part of the volume. The other essays are : 
“ Evolutionary Ethics,” “ The Philosophy of Thomas 
Carlyle,” “ The Brain Theory of Mind and Matter: or Hylo- 
Idealism,” “ Hylo-Idealism: The Creed of the Coming Day.” 
“ The Principles of Sociology,” and “ Animal Automatism : 
a Criticism of Dr. Huxley’s Essays on Science and Culture.” 
The volume also contains a short “Memoir” by Miss Nadeu’s 
friend, Mrs. Daniell, and a short “ Note” by Dr. Lewins, and 
has for a frontispiece an excellent portrait of Miss Naden, 
beautifully engraved, by G. J. Stodart. 
Dr. Lewins forwarded an early copy of the book to Mr. 
Herbert Spencer, from whom he has received the following 
interesting letter :— 
Fairfield, Pewsey, Wilts, 10th June, 1890. 
Sir, —Before I received your letter of the 8th instant, I was about 
to write expressing my thanks for the copy you have kindly sent me 
of Miss Naden’s “Induction and Deduction,” and other Essays. 
Already I had formed a high estimate of her intellect and character, 
and now perusal of some parts of the volume you have sent me has 
greatly raised my estimate. 
Very generally, receptivity and originality are not associated; but 
in her mind they appear to have been equally great. I can think of
