DEVELOPMENT OF FIREARMS in the 16 century produced profound changes in the art of warfare and raised new problems for the physician-surgeons. Old assumptions and wrong interpretations delayed the rational approach to the head injuries inflicted by missiles. Evolution of thought and increased experience over the century ultimately led to a surgical practice that can be regarded as the best possible solution allowed by contemporary knowledge and technology.

Synchronization of the acoustic evidence in the assassination of President Kennedy.
We have revisited the acoustic evidence in the Kennedy assassination--recordings of the two Dallas police radio channels upon which our original NRC report (Ramsey NF et al., Report of the Committee on Ballistic Acoustics. National Research Council (US). Washington: National Academy Press, 1982. ⋯ In particular we have used recorded 60 Hz hum and correlation methods to obtain accurate speed calibrations for recordings made on both channels, cepstral analysis to seek instances of repeated segments during playback of Channel 2 (which could result from groove jumping), and spectrographic and correlation methods to analyze instances of putative crosstalk used to synchronize the two channels. This paper identifies serious errors in the Thomas paper and corrects errors in the NRC report. We reaffirm the earlier conclusion of the NRC report that the alleged "shot" sounds were recorded approximately one minute after the assassination.
