This distinguished botanist died on the 4th of January, in his seventy-first year. Few men have done more to make American botany popular than he. His works - marred somewhat by typographical errors - were in universal use as text books, and while the more careful and strictly critical botanists have their useful field of work which progressive science finds indispensable, it fell to Prof. Wood's field to make this carefully gathered knowledge widely distributed. His rank was not, perhaps, in the highest fields of botany, but it was no less useful, and there are many hundreds of people deriving pleasure in life from botanical studies, who would never have experienced these delights but for his labors. We are quite sure there are few botanists whose decease will be more widely or more sincerely mourned than Prof. Wood's.
