Dear Madam

My chief reason for believing that Drosera drew the greater part of its nourishment from captured insects was its growing where no other plants could grow.¹ I began experiments on the comparative growth of plants with and without insects, but failed by the plants being accidentally poisoned.² It seems to me likely that the chief difference would be in the production of seeds. I did not observe the developement of the glands as this had been partly done by MM. Grönland & Trécul; but M^r Bennett has recently read a paper on these glands which is published in the Monthly Microscop. Journal Jan 1876.³ I can hardly believe that they are modified stomata.⁴

I am glad my book has interest you. | Dear Madam | Yours faithfully | Ch. Darwin
