Four sets of manuscript notes for unidentified lectures, possibly the Royal Institution Fullerian series of lectures (see F.3).

One page of notes, and a further untitled page found with it and possibly related.

The notebook has the title 'Heredity & Variation' inscribed on the first page, with 'Bateson' written above it. Contents are notes in Sykes' hand, apparently taken during a lecture course by Bateson, with intercalated pages of further notes. Used from both ends.

Manuscript notes by Bateson on variation in various insects, birds and mammals, in connection with published literature.

Correspondence to Bateson re various plants, including sweet and bitter almonds and Dutch brown beans; 6pp manuscript notes mostly in Bateson's hand.

30pp typescript draft with manuscript corrections.
