Vote of thanks to the late President. 
It was moved by Dr. Wallich, seconded by Dr. Boott, and unani- 
mously resolved :—That the most grateful and cordial thanks of the 
Society be offered to Mr. Brown for the admirable manner in which, 
for more than three years, he has conducted the business of the 
Society as its President ; together with the great and sincere regret 
of the Members that advancing years and the infirmities attending on 
them should have induced him to relinquish an office, in which it 
would have been their earnest desire long to have availed themselves 
of his invaluable services. 
Motacilla alba. 
Mr. Borrer, jun., F.L.S., exhibited specimens of a rare English 
bird, the continental white wagtail (Motacilla alba), killed at Lancing 
in Sussex, in April, 1853. 
New British Ferns. 
Mr. Newman, F.L.S., exhibited specimens of two species of ferns 
found in Scotland, and not hitherto noticed as belonging to the 
British Flora: one of which (the Polypodium rheticum of the ‘ Flore 
Frangaise, but not of Linneus) he believes to be the Polypodium 
alpestre of Hoppe; the other he considers to be new, and proposed to 
call it P. flexile. (See Phytol. 974). 
Correction of a previous error. 
I am indebted to my friend Mr. Doubleday for pointing out a cleri- 
cal error in the notice of Mr. Moore’s Handbook, at line 9 of page 
1158 of last number: the word “ uliginosa” should have been written 
“ slandulosa.” This correction is important to the right understand- 
ing of the notice in question.
