Specialty trades can be mysterious enough without trying to understand the tools they use, the supplies they go through, and the way they communicate these needs to each other. Jargon meant to be exclusive to those in the know, is at times disconcerting to the uninitiated. For example, I have an empty bottle of embalming fluid labeled Frigid Jr. with a picture of a fat healthy smiling baby on it. It is supposed to be specially formulated for babies .... what can I say?
I managed to find a ca 1920 copy of the Undertakers' Supply Co. Catalog. (I've depended on eBay for a long time...) The catalog lists everything an embalmer could possibly need as well as furnishings for the funeral service and viewing. There is a section on special cases, diseases, and conditions that require special treatment, precautions, or materials. Here are a few pages which give one an idea of what early morticians and undertakers were shopping for.
