To J. S. Burdon Sanderson 18 October [1873]1
To try whether Mucin (made by Dr. Moore from a large quantity of mucus), Globuline (from lens of eye) Chlorophyll (now in alcohol & to be evaporated) & Hæmaglobin, can be digested.2
Is Chrondrin more nutritious or more digestible than gelatin?. Dr. Moores says it is more nutritious.3 It acts more efficiently on Drosera than does gelatin; but neither of them at all so efficiently as juice of raw meat, or meat, or albumen &c &c. If not generally known, perhaps Dr. Brunton4 wd. know
If I can get Propionic & Butyric acids, would it be troublesome to ascertain whether these with pepsine will digest albumen & meat.5
