Sentence:  Pray tell R. Sheen, I am hugely displeased at his reprinting the Nativity Hymns, and omitting the very best hymn in the collection—All glory to God in the sky, &c. I beg they may never more be printed without it. Omit one or two and I will thank you. They are <WSD>"namby-pambical</WSD>". I wish you would give us two or three invitatory hymns. 
Meaning of the word marked with <WSD> tags:  Having a namby-pamby character; insipid, sentimental, or weak.
