either Kew or British Museum has any. When I was on the 
Albula in 1877 I came upon the hybrids between G. lutea and 
(1. punctata, and I could only find two forms ; the one nearer to 
one parent and the second nearer to the other. On the Albula 
too 1 looked for hybrids between G. verna, brnru ica and hracht/- 
pht/lla, and found them numerous and gathered many specimens 
and I don't think I ever found more than one form of hybrid 
between each species. 1 used to lie down on the grass among 
them, and could always detect the hybrids by the different tinr 
of blue they showed. Everywhere that [ have botanised I have 
always been on the lookout, and I have never seen any case 
of ' Uebergangsf ormen.' I may say the same of Pedicularis. 
Primula, Achillea, Campanula, Saxifraga. One usually finds 
either a hybrid exactly between the parents ; or two, one nearer one 
piii"; n • the other nearer to the other ; or three ; or finally four, as in 
'^■"inila -minima x P. ghttinnsa, where you have P. 7 
'•^P-/''-.'' 7 " '""«■' ■ minima), P. salisburgensis (sub-glutinosa x 
"tin/ma), P. llutrri {Flnrrknma x gh/finosa), and last P. bi flora 
(■*"' "•■"">■.'/''"*'* < minima). Among Girsia, however, Dr. Focke 
records G. rwulare x pallet re, rivulare x acaule, and oleraceum 
x nr„uh as producing several ' Feb, r-m-sior m , n .' But com- 
pared with the numerous cases of hybrid Girsia, the number of 
N>— snowing 'Uebergansformen ' is. I think, verv small. It seems 
lo me that Huxley rushed too quickly to his conclusion.." In a 
• ianuary .",1, IX'.U, n.mvhil] wrote :—" as regards the 
statement .... that horticultural experience does not 
confirm my view as to the limited number of hybrid forms in 
eacn case 1 would reply that horticulture upsets the old state of 
Daiance of the conditions, and that therefore different results 
would arise. In nature the equilibrium does not quickly change, 
and therefore the new results are fewer. If you refer to all the 
best floras of Europe i think you will find that « Febergangs- 
formen are exceedingly few. So far as I have examined it is 
so. Once more, February 10, 1891:— "If 'Febergan^slbrm.-n '

across such. Prof. Bruegger of Ohur is about the greatest
