The Quarterly Journal of Science—October.—This number contains an interesting article
by Captain Tyler on the means of communication in railway trains, from which it appears that the objection of the public to being quietly murdered or burnt is really being looked into, one com- pany, the South-Western, having a voltaic apparatus for complete outer communication already in work. There are also readable papers on the "Mammals of South America," by Mr. Sclater, with a good typical illus- tration depicting a scene in a Brazilian forest, and the "Identification of Strata," by the Assistant-Secretary of the Geological Society ; a short sketch of British gold discoveries, which are not encouraging, by R. Hunt, F.R.S., and some technical writing on the "Quality of Musical Sounds," by W. S. Squire, Ph.D. The remainder of the number is taken up with the usual "Chronicle of Science."
