V. Note on the influence exercised by light on organic infusions

Abstract

Early last June I took with me to the Alps 50 small hermetically sealed flasks containing infusion of cucumber, and 50 containing nip infusion. Before sealing they had been boiled for five minutes the laboratory of the Royal Institution. They were carefully cked in sawdust, but when unpacked the fragile sealed ends of out 20 of them were found broken off. Some of these injured tsks were empty, while others still retained their liquids. The 80 broken flasks were found pellucid, and they continued so throughout summer. All the broken ones, on the other hand, which had tained their liquids, were turbid with organisms.
