venience in my business from the want of fine examples of 
many of our native water-birds, I came to the determination, 
in the early part of 1831, of visiting the Orkney and Shetland 
Islands, for the purpose of procuring some of the rarer kinds.” 
He further informs us that the book arose out of his custom, 
on this and three subsequent journeys, to take notes of his 
routes and of the occurrences that took place, etc. Mr. 
Harvie-Brown says that “ if his statements are entirely to be 
relied on, the avifauna of the islands has much altered within 
the last fifty years, as will be seen by a reference to the 
various species. Dunn was more of a collector than a 
naturalist, and, we are afraid, contributed not a little to 
the decimation of the rarer birds of both Orkney and Shet- 
land.” We are unaware of the precise date of his death. 
His last communication to the Zoologist was dated from 
Stromness, January 24, 1859, and on December 12 of the 
same year his son Joseph began his communications in his 
father’s place. Joseph Dunn settled at Stromness, where he 
resided for many years, and where he died November 28, 
1872, from the capsizing of his boat. He was well known to 
ornithologists visiting the islands.
