Some interesting- investigations Of the effects produced on the ears1 <o£ the artillerymen by the noise of- £fie> firing of- cannon have been mafle/ "by Dr. Muller, says "Scieilce Sittings." It appears that in 3a artillerymen out of 96, no alteration of > hearing1 could be discovered, whilst in. the remaining 44 the drum' of the ear was deadened or rendered less sensitive to sound. This occurred almost eXclti' siyely in ears which were weak at thp outset; the men also made dtimpiaint of subjective sounds that were hearo subsequently to the artillery' practide, j Dr. Muller found that men' who only, served for two years were not •permanently injured, for the*' chalige'S in the ear are generally recovered from jafter the men leave the; army* Artillery officers) however, and' sergeants of long service, not infrequently suffered from partial deflf- : ness. From this, as the "Lancet" points out, it follows that men in whom there is any reason to.Suspect weakness of auditory orgnnsi ought , not. to become artillerymen, v, ;; ; ;
