In Mrs. Bridge, Evan S. Connell’s “log-log duplex decitrix” (Chapter 49) appears to be a small error for the Keuffel & Esser Log Log Duplex Decitrig slide rule.
Similarly, this sentence from Chapter 13, “Guest Towels,” is initially confusing:
She had a supply of Margab, which were the best, at least in the opinion of everyone she knew, and whenever guests were coming to the house she would put the ordinary towels in the laundry and place several of these little pastel towels in each of the bathrooms.
Slantwise searching turns up Cynthia’s Linen Room:
Marghab Linens were produced in Madeira, Portugal between 1934-1984 and were marketed as some of the finest embroidery of the time. Vera Way Marghab was the driving force behind the imaginative and beautiful designs executed by her company, Emile Marghab, Inc.
The linens were hand-embroidered as a home industry by the Madeirans.
