notice of the preceding paper, he had been led to look over the notes of hia analjtee 



of KiUinite, given him by Dr. A. Smith, and also tlie Icck-grecn specimen men- 

 tioned. The results of these analyses Mr. Haugbtou had already stated. Kil- 

 linite is a mineral which has only been met wiih in Ireland, and then only in 

 KiUiney Hill, near this city. Several attempts have been made in Crermany and 

 eUewhere to identify this mineral with Finite and other minerals, but without 

 •uccees. He would nut detain Uie Society with a detailed analybis of the mineral, 

 as several most accurate analyses have been published — the tirst by Leight mad 

 Blythe, and since then by liobert Mallet, and others. He found, however, one 

 discrepancy between the analyses of these gentlemen and his own— viz., thequautiiy 

 of water present as their analyses gave ten per cent., while his gave only eighL 

 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 thej 

 showed that the specimens of Killinite vary in the proportion of water pres^it — 

 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 mouth of June.

ON BOTRTCUIUM LUNABIA — ITS MOST BKMARKABLE 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 

 1 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 il 

 as a digitate subvariety of lunaria, and pointing out its bearings as illustrative of 

 the relations subsisting between the two, as they are called, ^^ fronds" of the ordi- 

 nary plant ; but into the relations subsisting between it and the classes of moostrons 

 forms — on a former occasion laid before this Society in some detail — I did not at 

 all enter ; for, having foimd but three plants partaking of these characters, it
