ABSTRACT
Besides these monographists, who were highly regarded in their own day and are still well worth reading even nowadays, there lived during the eighteenth century many scientists whose works embraced fields of research of wide extent in regard to both the material investigated and the problems dealt with. In particular, experimental biology and theoretical questions in connexion therewith were developed on a considerable scale during this period by scientists who have merited the attention both of their own age and of posterity. Foremost among these should be mentioned Haller, a great man in his own age and a scientist for all time, famous as a botanist, anatomist, physiologist, statesman, and poet.
