My Dear Sir

In reply to your letter which I received here yesterday I do not believe the common Goose sifts the water out of the sides of the bill like a Duck.¹ But some species of Geese that feed more in the water, may use the bill partially in this manner, but most species of Geese feed on the land, but I think the Black and White Goose of Australia, is the bird most likely to have the lamellæ less developed than any other Goose, we have the bird alive in the Gardens, I have written to my son and asked him to look at the bird and report to you.² On the other hand I think the Snow Goose of North America has the lamellæ stronger than any other Goose, they are in fact like powerful well developed teeth.³ I have forwarded your letter to my son and you may depend you will hear from him. I shall be home in a few days, and again think over the matter

Yours faithfully | A D Bartlett

P.S. The Black & White Goose of Australia has the webs of the feet less developed than any other Goose.
