White not only notes the homes and ways, the times and seasons, of plants and animals - comparing, for instance, the different ways in which the squirrel, the fieldmouse and the nuthatch eat their hazel-nuts - or watches the migrations of birds, which were then only beginning to be properly recorded or understood, but he knows more than any other observer until Charles Darwin about the habits and the usefulness of the earthworms, and is certain that plants distil dew and do not merely condense it.
To obtain the free acid it is best to dissolve the diazohippuramide in dilute soda, warm the solution to ensure the formation of the sodium salt, and distil the resulting liquid with dilute sulphuric acid.
