Since —— the above I have seen at Chailly, near Vevey, @ 
meadow in which grew numerous plants of P. veris quite up to a 
low stone nae on its northern side. Not one P. acaulis was to be 
seen among them, but immediately beyond the wall, and extending 
for a few feet only from it, P. acaulis was abu ndant. The wall 
stood on no bank or slope, and I could perceive nothing different 
in the conditions on the two sides of it, except that of course the 
meadow on its north side for a little way was shaded from the mid- 
day sun. There was no P. veris among the P. acaulis, but further 
to the north from the wall P. veris occurred again without P. 
acaulis, I could not but connect the presence of P. acaulis and the 
— of P. veris with the wall; yet the wall, though not a new 
one, must have been of trifling ‘duration compared with the time 
generally accepted “ necessary for the conversion of one species 
into ano st 
On a small grassy mountain slope I found the three Primulas: 
growing, Sith acaulis was almost confined to the parts sloping least 
to the south, and elatior to those most soaked with moisture.
