There are a couple of others somewhere in the file, but I remembered an
easy one (book is on shelf behind me): The Practical Photographer Series
on Gum-Bichromate Printing, 1905: page 64, #2 in a list of options for
sensitising solution:
potassium bi-chromate 10%, 10 parts; methylated spirit,
1 part; gum solution (40%), 10 parts; pigment quant. suff.
That "quant. suff." is in italics, I assume Latin for sufficient quantity.
