“ciples of terminology and classification, natural _ 
and artificial, as is deemed subsidiary to the im- 
mediate acquaintance of the student with Materia 
Medica ; in other words, the principles and details 
of Medical Botany, so set forth, that an amalga- 
mation of them with the details of materia medica 
oper, so natural and useful, will be found easy 
to the student. tabi
