EDUCATION, SCIENTIFIC AND TECHNICAL: or, How 
the Indudive Sciences are Taught, and How they £)ught to be Taught. 
“ This book is an addition of not immaterial weight to the voices of protest 
already lifted up in considerable strength against the system of cram and 
shallow paper-work that has within the last twenty years been spread abroad 
in this country under the name of education. Mr. Galloway combines the 
qualifications of a man who has read and thought seriously about the principles 
of education in general with those of a specialist who can bear witness from 
his own knowledge to the right and wrong methods of teaching in his own 
subjed.” — Saturday Review.
