[ Grenfell / Vikings of To-Day ]
Sir Wilfred Thomason Grenfell (1865 - 1940) was an English physician who devoted his career to providing medical and social services to the inhabitants of Newfoundland and Labrador; he was knighted for that work
Vikings of To-Day: or, Life and Medical Work among the Fishermen of Labrador, first published in 1895 (London: Marshall Brothers), was the first of many books Grenfell wrote about his experiences in Labrador and Newfoundland.
The only reference — an indirect and somewhat ambigous one — occurs in Chapter 13, "On Dogs and Difficulties":
The Esquimaux dog, unlike his Newfoundland congener, is by no means a fiction, being an ubiquitous feature of Esquimaux life.
A "congener" is a person or animal or object that belongs to the same class or type as another person/animal/object. As I take it, Grenfell's apparent suggestion that Newfoundland dogs are a "fiction" refers to the near-absence of Newfs on their island of origin, an observation which is confirmed by other works written around the same time as this book. For more about this topic, see "The Disappearing Newfoundland of the Late 19th and Early 20th Century" here at The Cultured Newf.
Another of Grenfell's books is treated briefly here at The Cultured Newf: Labrador Days: Tales of the Sea Toilers.
Grenfell is also the subject of two biographies discussed here at The Cultured Newf: Fullerton Waldo's With Grenfell on the Labrador (1920) and Dillon Wallace's The Story of Grenfell of the Labrador (1922).
