With regard to a number of earlier messages on the efficacy of using inert gase s. We have published a number of papers on the use of nitrogen for pest eradica tion. These include mortality studies on common museum pests in nitrogen, as well as methods for treating various size objects using this technique (From a small book to a 1938 Dodge). The methods developed help to maintain the same hu midity and temperature from which the object came from. It is cheap and easy to use. If you need reprints of the papers please send me a email at VDANIEL@GETT Y.EDU Vinod Daniel Getty Conservation Institute (310 822 2299)
