NOTES AND EEEATA. (Part II.) 



Page 92. Cones from the same two trees of Pinus austriaca and P. la/ricio 

 have been counted by Mr E. G. Broome for 1902 with similar one-sided 

 results. 



Thus P. Laricio (1902) :— 



69-16 L. and 30-33 R : 



a result practically identical with that of the two preceding years for the same 

 tree : the average for 1100 cones during the three years being 



69-82 L. and 30-18 R. 



Pinus austriaca (B.Q.O. 1902). 

 being counted : — 



-A poor crop only admitted of 500 cones 



the average being 54 R. and 46 L. The result again is sufficiently identical 

 with that of 1901. It may be pointed out that two of these batches gave very 

 widely different results, in one batch a preponderance of left-hand cones being 

 found, a fact which serves to show that 100 is too small a number to give a 

 satisfactory conclusion. The average result for 1600 cones during three years 

 for this particular tree is thus 



54-06 R. and 45-94 L.
