Summary:

Comments on two letters received from W. F. P. Pfeffer [13425, 13464] who thinks Julius Wiesner’s view that light, etc. acts directly on plants is wrong.

Is frantic over the number of letters received about worms; feels the enthusiasm of the reception of Earthworms is laughable.

Is confounded by Euphorbia rootlets and has re-examined the effect of carbonate of ammonia.

Has thought of three good experiments to oppose Wiesner.
