The same must be said of No. 28, Acer, with G"5. The only 

 other quite reliable instances of a proportion exceeding 5 p.c. 

 are Ci/tisus Lctburnum, with 7 p.c, and Castanea vcsca, with 6 '5 

 p.c. The only instances of 5 p.c. occur in Fagus, Nos. 8 and 

 , 9* ; of 4"5 p.c. in No, 81, Carpinus, and No. 19, Cratccgus ; and 

 no others exceed 3 p.c. Thus only thirteen of the fifty-eight 

 exceed 3 p.c, and of these only nine are perfectly reliable. 



May. Large proportions occur in all three specimens of 

 i^rfla'i?i«s, 21, 26'5, and 30 p.c; in all three of Qucrcus Cerris, 

 20, 22, and 28 p.c. ; in two of the five examples of Q. Bohur, 

 20'5 each ; in Ulmus,- 25 p.c. ; and Fagus, 22 p.c. Thus in 

 only ten of the fifty-eight the proportion attained 20 p.c. or 

 upwards, and it is remarkable that all the three Ashes, all 

 the three Turkish OaJcs, and two of the five English Oaks 

 are included in this small number, 



June. The largest proportions are in two of the three 

 examples of Tilia, 54 and 53 p.c. ; in all five of Acer, 37, 

 38'5, 40, 40"5, and 47 p.c; in Fraxinus, 53 p.c. ; Pojmlus 

 alba, 40 p.c; Bctula, 38'5 p.c; Alnus, 38 p.c; Primus, 

 Pyrus, and Ulmus, 36 p.c. each. Thus 35 p.c. was exceeded 

 in fourteen of the fifty-eight, including all the five Sycamores 

 and two of the three Limes. The tendency of certain species 

 to a large proportion in this month is confirmed by the 

 second specimens of Bctula, Primus, and Ulmus being near the 

 average of the month. Poimlus alba and Ahius are single of 

 their kind. Both the young Limes and one of the young 

 Ashes accomplished more than half their aiuiual growth in 

 this month. 



Jidy. A high percentage in this month occurs above all 

 in the genus Qucrcus. All the five specimens of Q. Pulnir 

 figure with 36*5, 39, 41, 42, and 43-5 p.c ; the single Q. rubra 

 and Q. palustris with 39 and 41 p.c ; two of the three 

 specimens of Q. Cerris with 35 and 37 p.c. ; and one of the 

 three of Q. conferta with 35'5. The remaining examples of 

 the genus, Q. conferta (two) and Q. Cerris, are well up, with 

 34, 34, and 31 p.c, all above the monthly average. Of the 

 eleven examples of Fagus, five appear with 35, 37*5, 40, 42, 

 and 48 ; and of the others only one is below the monthly 

 average. The two specimens of Pyrus stand well, witli 

 34 '5 and 40 p.c; also yEsculus, with 35 and 34; other 

 cases willi large July ]>.c., but in which the tendency
