Adding more to my reply, this posy trough is Sowerby pattern 1219 shown in pattern books 8 and 9 (1882). It is illustrated and discussed in Simon Cottle's book "Sowerby: Gateshead Glass".
The poem from Crane's book (for the letter E) goes:
"Elizabeth Elspeth Betsy and Bess,
they all went together to seek a bird's nest,
they found a bird's nest with five eggs in;
They all took one, and left four in."
(thanks to Simon Cottle's book for all that information)
