notice of the preceding paper, he had been led to look over the notes of his analyses 
of Killinite, given him by Dr. A. Smith, and also the leek-green specimen men¬ 
tioned. The results of these analyses Mr. Haughton had already stated. Kil¬ 
linite is a mineral which has only been met with in Ireland, and then only in 
Killiney Hill, near this city. Several attempts have been made in Germany and 
elsewhere to identify this mineral with Pinite and other minerals, but without 
success. He would not detain the Society with a detailed analysis of the mineral, 
as several most accurate analyses have been published—the first by Height and 
Bly the, and since then by Robert Mallet, and others. He found, however, one 
discrepancy between the analyses of these gentlemen and his own—viz., the quantity 
of water present as their analyses gave ten per cent., while his gave only eight. 
This fact, taken in connection with the extreme accuracy of their other analyses, 
furnished an additional proof of the truth of Mr. Haughton’s statement, as they 
showed that the specimens of Killinite vary in the proportion of water present— 
a discrepancy well known to exist between specimens of most hydrated altered 
minerals. He perfectly agreed in the justness of Mr. Haughton’s views, and con¬ 
sidered the identification of the minerals as most valuable. 
The meeting then adjourned to the month of June.

ON BOTRYCHIUM LUNARIA—ITS MOST REMARKABLE VARIETIES. 
It may be within the recollection of some of your members that, two years ago, 
I brought before this Society some specimens of varieties of the common moon- 
wort (Botrychium lunaria), including two exhibiting a deltoid outline. I hope 
I will not be thought to be fruitlessly occupying the time of the Society “ with 
a twice told tale” if I again call your attention to this variety. On the former 
occasion, being on the eve of my departure for Australia, I did no more than draw 
your attention to the form. Indeed, its full value in reference to the laws of mor¬ 
phology did not at that time strike me, and I contented myself with recording it 
as a digitate subvariety of lunaria, and pointing out its bearings as illustrative of 
the relations subsisting between the two, as they are called, Li fronds” of the ordi¬ 
nary plant; but into the relations subsisting between it and the classes of monstrous 
forms—on a former occasion laid before this Society in some detail—I did not at 
all enter; for, having found but three plants partaking of these characters, it
