of tliem ai'o now in capital condition. After securing a few eggs 
wc hurried from the spot, as the remains of the fish which had 
heon di.sgorged by tlie parent birds for tlie benefit of their young, 
rendered it anything but a pleasant place. A little lower down 
the rock we saw nests of the Shag, some with fresh eggs, 
many with young ; the naked condition of some indicated that 
they were Imt recently hatched, others had a covering of sooty 
down, evidently two or three weeks old, and again, some were 
nearly full feathered. As wo wore returning to the boat, Ave found 
a nest of the Oystercatclier with its full complement of tluee egg.s. 
A^’’e then steered for Illiswilgig, a small island with a conical 
hill, on the very summit of which was placed a ne.st of the Great 
1 Hack-backed Gull, whilst on the lower ground were the nests 
of the two commoner species, ami Shags’ nests Avere seen under 
many of the granite boulder.s. 
Scrambling over the rough sea-we(>d-covered stones, on our 
return to the boat, avo found an enormous number of Limpct.s 
fPaleUa athleticaj, many of Avhich hail attaimal a size unu.sually 
large even for this species.'*-' 
Keeping to the nortliAvard, avo ne.\t rowed to the grandest 
and most picture.S(pio rock in the archipelago — ^Icnavore, It is 
divided into three lunnacles by Avido chasms, Avhoso sheer .sides 
afford good places for the rock-bird.s. "We Avero able to secure 
a landing on the most easterly portion of the rock, and after a stiff 
climb AVO reached a long plateau, from Avhich avo liad a good vieAv 
of the precipitous sides. In addition to some finely marked eggs 
of the Ivazorl)ill, avo hero obtained our lii-st egg of the Guillemot. 
AVo did not see any other birds on this reck, although it presented 
to the human eye every attraction for the KittiAvake, a bird Avhich 
Avas in constant attendance upon the yacht in Grimsby Harbour, 
but Avhose nesting-place Ave Avero not able to find. 
When Ave had reached the higher ledges of the rock, our 
* Mr. Edward Lovett ot Croydon tells me that he has observed a variation 
in form according to situation both in this species and P. vulgata. When 
the Limpet has established it«elf on the side of a rock f.acing the sea, which 
is exjiosed to the full force of the waves heating upon it, the shell liecomes 
l>ointed and of great strength and thickness at the apex ; hut when living in 
a channel where the water rushes b)' it, the shell is found flattened 
and spreading, the sides thus oflering little resistance to the passing 
waves.
