When the case was opened at the end of eighteen months, the loaves were reduced to a small mass, consisting almost entirely of filaments of mould, in which I could detect no trace of the substance of bread. This mass was soft and moist, like a mud-pie. It emitted a strong odour of trimethylanrin: no trace of starch remained. One hundred parts in weight of the original bread were transformed into sixty-four parts in their moist state, and seventeen parts after desiccation in the open air. The starch had been consumed in order to form carbonic acid and ; Badham sums up in a few words the destructive effects of microscopic fungi. " Mucor m/w- ceclo," he writes, " devours our pre- serves; Ascophora Tnucedo turns our bread mouldy; Molinia is nourished at the expense of our fruits; Mucor herbarium destroys the herbaria of botanists; and GhcBtoniuni chariatuon (Actino- spora) develops itself on paper, on the insides of books, and on their binding, when they come in contact with. ^ Fig. 19.—Ckcptoniiim char- tatwm, mould on Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Trouessart, E. -L.
