Sbctiox L — Oa the Meagare of Corretpomdeace between the 



distribution of the £a ■ if all and that of Forests, 256 



Ti j is iii jstrated from sUtemeots by Dr B.-andis in regard to India 

 (p. 23o I. by Mi Murlaren in regard to America (p. 259). by a crm- 

 fiari£oa of report on the laii^fall in North America, issaed by the 

 SmithjODian Insimtion (p. ioii. with the account of the forests 

 of North America given by M. Mamy (p. 261); and a statement 

 in legaid to the descmction of forests in Soath Africa ^p. -6J|. 



Seciiox II. — On, the Distribution of the Rainfall dependent on 

 Geojriphieal Positionj beinj determined by the Contour of 

 a Country, - 271 



An illostration of the distiibntion of the rainfall being affected by the 

 alUtuie of a conntiy is giTeu in the effects of a wiad-wave which 

 passed over Europe in Septiai'Mr lSo5 (p- i'Tii ; with an il'.asiri- 

 tion of the same operation in the prodaction of & ^ mackerel skv" ; 

 and of the Table Cloth on Tab'.e Monntain (p. 273). Which are 

 foUowed by an ezposition by Cezanne of his doctrine that it is 

 determined in a great measare by the lapidiy with which the 

 atm:spheric current rises (p. 274); and illustrations of this being 

 the use supplied bj Banlin (p. 230). 



Szcnox TTI. — On the Distribution of Fore^ Affected by the 



Distribution of the Rainfall, 283 



Thoe is dted a siatemimt by Maish lelaliTe to a tendency manifested 

 by ligneous vegetables to secure the unireisal occupancy of land 

 (p. 2S3). The operation of laws regulating the dispersion of 

 vegetables is illustrated (p. 2Sc' : and the opoationof these on the 

 dispersion <^ trees is seen to depend in part upon the rainfall 

 (p. 2S9). 



Sbctiox it. — On the Local Ejects of Forests on the DistrSnt- 



tion of the Ei iifall within «ftc F-yrest District, 293 



The general effect of fwests is shown to be to retard the Adw of the 

 tain-water precipitated (293), and so in prehistoric times to hsTe 

 eonvoted torrents into peaceful streams (294), while the s^oie effect 

 is shown to be produced by them still (p. 295). There are cited 

 observations adduced to prove that apparently they inffaenee some- 

 what the qaaEtrT of the rainfall and the local distribct'on of it over 

 the year (p. 299) ; and the reeondliaiion of conflicting obseivations 

 and opinions (p. 302) is shown to be possible (p. 303).
