Royal Botanic Garden, Glasnevin, Dublin, 
February 1st, 1842. 
My dear Sir, 
I find all the species of ferns I have tried, 
to grow well either in glazed Wardian cases, 
under hand-lights, or in close frames, when the 
external air can he excluded, where some of the 
slender-growing kinds develope their fronds to such 
a degree of beauty and elegance as I have never 
observed excepting under such circumstances. 
I may especially notice our rare and beautiful 
Trichomanes speciosum, Willd., which can be cul- 
tivated to very great perfection on this plan, and 
is here, at this time (1st February, 1842), in a 
fine state of fructification, producing larger fronds 
than it usually does in its native habitat. Hyme- 
nophyllum Wilsoni , Hook., and II. Tunhridgense , 
Sm., delight to grow in these close cases, and, 
when properly cultivated, attain to a larger size
