SUPPLEMENT TO LINCOLFS BOTANY. 
BY THE AUTHOR, 1860. 
This Supplement will furnish the students of Lincoln's Botany with 
a method of analysis by the Natural System, as simple as any which has 
yet been devised. In preparing this Artificial Key to the Natural Or- 
ders, the author has availed herself of the Table published by Lindley, 
in his School Botany, also of Be Candolle's Methode Analytique^ on 
which Lindley's Bichotomous Analysis is founded.* 
To the beginner, the author would still recommend the method 
pointed out in Part I. of this book, from page 14 to 26. That " the 
diffijculties attending analysis hy the Natural System alone are too great 
to he successfully encountered at the threshold of the science" it is useless 
to deny. The attempt to do this has rendered Botany far less popular 
than formerly; and has, in a degree, excluded it from many schools 
where it was once a favorite study. But learned professors are begin- 
ning to see the error of attempting to exclude the name and labors of 
the great Linnaeus from the science of which he was the father; as 
well might the name of Euclid be cast out of the science of Geometry, 
or that of Newton from Astronomy. 
The student will need to go on with the study of Vegetable Physi- 
ology and Structural Botany, in Part 11. , in order to understand the 
principles on which the Natural System is founded, and to become 
familiar with the language and distinctions of the science. In Part III. 
will be learned the various methods of classification ; and the mind will 
become gradually familiar with those important characters of plants 
which, under different views, have served as distinctions to the several 
divisions. In the review of the Linnaean Classes and Orders which 
occurs in this part, the prominent Natural Orders are noticed ; when 
these are divided by natural distinctions, the fact is remarked as an evil 
inseparable from the Linnaean system. But the Natural System, which 
professed to be able to do so much, has as yet been subject to many 
and great changes and anomalies. No human science is perfect. The 
Natural System of Botany, as improved during the last half of the 
♦ Tlie author being in Switzerland, in 1854, had the privilege of visiting Prof. Adolph De Oan- 
loUe, at Geneva, and of examining with him his gi'eat Herbaria, the largost, probably, in the 
world ; enriched with the treasures which his distinguished father Jiad collected. It was at this 
time that Prof. De CaadoUe presented to the author his father's v»crk above referred to.
