An article by Brian Lemin that compares how eight published authors, from Wright (1919) to Springett (1996), describe Church Window, Mother-in-Babe, Cow-in-Calf and Jack-in-the-Box lace bobbins. It treats Wright as the benchmark source, points out contradictions (for example Huetson's 'baby bobbin'), and proposes standard definitions: Church Window (empty slots), Mother in Babe (contains a small bobbin), Other Inserts or 'Lantern', Jack in the Box and Cow in Calf. It ends with a speculation that the inserts may originally have been candles, a call for collectors' feedback, and a reference list. Three photographs of example bobbins are included.
