Book excerpt: Excerpt from The Essentials of College Botany In offering this book to college teachers it may not be amiss to refer to the great change that has taken place in the teaching of Botany in America since the preparation of its predecessor thirty-five years ago. Then botanical laboratories were just coming into existence, and for the first time students of Botany were able to study- protoplasm and cells and tissues and other minute structures of plants. It is a matter of history that half a dozen years later the publisher's objection to the caption Laboratory Studies for a new edition, was able to bring about the substitution of "Practical Studies," as less likely to prejudice teachers against such presentation of the subject. Looking back to that time we realize what progress has been made in the teaching of the science, for to-day every college has its laboratory for the study of plant structure, and this change in teaching has gone so far that it has invaded the secondary schools, in which there are now many well-equipped botanical laboratories. Looking at the science from another standpoint it is of interest to note that thirty-five years ago the number of species of known plants was between 125,000 and 150,000, while to-day it has risen to more than 233,000. Then the number of flowering plants was placed at a little more than 100,000, while now it is about 133,000: then the lower plants ("cryptogams") were thought to number from 25,000 to 40,000, while now there are more than 100,000 enumerated.
