(There have been some changes since last recorded observations). Ring about pupil. First comes the ring surrounding the pupil, now distinctly brassy in hue. It is noted that the outer circumference is not what the botanists would call "entire"; it is serrated, so that the ring looks, at close range, like a gear wheel with irregular teeth. Change in iris. The next portion of the iris is dark brown but towards the edge it has now become lighter in hue--very much lighter in fact--and has a lavender tinge in it. Sclerotic coat. The sclerotic coat (I suppose it is that--beyond the cornea) is not white as in human eyes, but brown again Skin patch. The skin-patch back of the eye has not changed in its colors in any noticeable way since last observation was recorded. The "red" is still dull and faded in appearance--it almost seems duller. Lashes The moulted eye-lashes have been completely replaced. They are now no longer "white" at the inner ends. (To be confirmed). (GK rec 31) Lash spectrum. Viewed at close range under intense illumination, each lash is seen to give off an impure diffraction spectrum. Other Characteristic RR features. Halo. The halo formed by the fine hairs that project beyond the feathers of the head and neck also, when viewed under strong illu- mation give off spectra. The hairs are close enough together to cause these spectra to blend. "Beards" The long hairs under the chins have been undergoing replacement and are still covered for about a third of their length by sheathes. These "hairs" are nearly white, but some are black. A's bald spot. In the eight day period that has elapsed since Archie scraped off a considerable portion of his head feathers new ones have grown out about one eighth of an inch (3 mm. plus). Hroo call ceases Some time ago it was noted that, first A then followed later by T, had acquired the soft, low, pleasing, adult hroo. This has not now been heard from either bird for some weeks. Tongue tips. First the tongue tips were pink, then "black"; now they are almost white and look like horn. This was first noted in Terry who had swallowed all but the te il of a mouse. The tail stuck out one side of his gape and his tongue was crowded out the other. Bill tips. These have changed in color, from bluish-slaty to yellowish- white horn-color. Presumably becoming harder. Pellets. Yesterday Archie began saying pulk, pulk and shaking his head, soon disgorging a pellet of mouse-hair--the seventh known to date. The evidence is that these pellets represent an accumulation over over a period of several days, the intervals being irregular and mouse diet the cause. November 11th. The humming bird was not in his roost by the west living-room
