Such are the results of my experiments, which I must own disap- 

 pointed me greatly, and interfered very materially with my previous 

 ideas of specific identity : we have certainly no direct change from 

 the primrose to the cowslip, or the reverse, but we have the change 

 in two steps, first, from the P. veris to P. veris, var. major, and then 

 from that to P. vulgaris, and however unwillingly acknowledged, such 

 transition appears really to take place. The change in P. Jacquinii 

 surprised me much, as I had not heard of its altering in form, and my 

 previous experiment only went to prove the contrary. 



I have now a large number of seedlings of this year's growth, for 

 the purpose of carrying on the investigation ; for the present I shall 

 say no more, but leave the above facts to speak for themselves.
