Musical notation of SEAL-WOMAN'S SEA-JOY is viewable online in the following book, digitized by Google:

Sea Tangle: Some More Songs of the Hebrides, collected, edited, translated and arranged by Marjory Kennedy-Fraser and Kenneth MacLeod (London & New York: Boosey & Co., Ltd., 1913), page 22.

—or at least it is viewable in the US. (I understand Google sometimes blocks certain things from certain countries depending on how it interprets the copyright laws of that country.)
