    Abstract: Fluorescence properties of the product of the reaction of the 2-naphthalenethiolate ion and 2-chloroethylethylsulfide or bis(2-chloroethyl)sulfide are described. The fluorescence of the latter reaction is used as the basis of a new detection method for 2-chloroethylethylsulfide. The detection method is capable of detecting 2-chloroethylethylsulfide at levels down to 0.2 micrograms per milliliter.

    Abstract: An animal feeding device which supports feeding dishes at an elevated level and which protects the food in the dishes comprises a housing having a roof portion which extends over a raised shelf. The shelf includes apertures into which the bottom of the feeding dishes are inserted. A cover overlays the shelf and is pivotally secured in the housing so that it can expose the feeding dishes. A treadle mechanism operates the cover and the housing preferably includes a handle for carrying and a light bulb for illuminating and heating the feeding dishes.
