My dear Mr Dyer

Your letter will be of much use to me, & it is very good of you, busy as you are, to write to me at such length.¹ Thanks for the heath seeds. I spoke about exalbuminous seeds merely like a parrot without any definite understanding.² I will write to M^r Ralfs.³

Will you ask Hooker whether he has kept a few references which I sent him about plants catching insects. One of these related to the bladders of Utricularia, & I shd be very glad to see it again.⁴ I have been writing to several quarters for Utricularia: I suppose you have no species at Kew. By the way Hooker thought he c^d get me another plant of Drosophyllum.⁵

My daughter writes from Wales that the little glandular leaves are from the “bog-heath”, whatever this means; she finds a great many of these little leaves on Pinguicola.⁶

She has found 4 additional seeds on the leaves. My son & I are trying ex^ts. with milk: what Linneus says about the Laplanders using Ping. to curdle milk is well known & the same plan used in Wales.⁷

yours very sincerely | Ch. Darwin
