flowers ill the course of a rnmble towards .Ferbonrpf, 1 found 

 much to ir»y surprise that they consisted of 

 2S6 ])in-centres, 

 '2H0 rose-centres. 

 Shortly after this, a lono- walk throuo-h lanes about the 

 Forest and in the neiohbourliood of Petit Bot yielded the 

 laro-est resuh for any single day, foi- no less than 1,018 

 s))eeimens were registered : and again the two forms w^ere 

 almost exactly equal in number, viz. : 

 o06 pin-centres, 

 512 rose-centres. 

 This was on the I2th of April, when Primroses were 

 hardly yet to be found in their greatest profusion ; therefore it 

 might be thought that this surprising eyenness in the numbers 

 was due to the earliness of the season ; but the same result 

 was shown next month. On the 8th of May we worked oyer 

 a part of St. AndreAv's, in the Talbots' Valley direction, and 

 registered 443 flowers, when the numbers proA^ed to be 

 228 pin-centres, 

 215 rose-centres. 

 At times the two forms were so exactly balanced that it 

 looked yery much as if they had been picked out for that 

 express purpose. Thus, on May 3, when Ave had by agreement 

 noted 200 flowers, I counted the forms, and found 100 of each 

 kind. Two days later a short stroll gave us 262, consisting of 

 130 pin-centres, 

 132 rose-centres. 

 Towards thp middle of June primroses had become few 

 and far between, and a large proportion of the blossoms 

 still scattered about here and there Avere imperfect, mostly 

 Avanting the reproductive organs, the stamens and pistil 

 having probably been eaten away by small insects. Con- 

 sequently in the course of our last Avalk we could only find 

 48 perfect tiowers, divided' thus : 



28 pin-centres, 

 20 rose-centres. 

 It sometimes happened that a day's result shoAved a 

 slightly larger divergence between the numbers of the two 

 forms than the instances I have quoted ; but in no case 

 did it amount to much, considering the variety of situations 

 we examined. The widest difference occurred on April 13, 

 when 591 flowers were made up of 



276 pin-centres, 

 315 rose-centres.
