Statistical Societies in France. 157 



vious fortnight (the Society to meet every fortnight). On par- 

 ticular days geological subjects proposed by the members are 

 discussed, and memoirs are read. A publishing Committee is 

 entrusted with the charge of publishing speedily extensive me- 

 moirs and maps, and separately. Each memoir will have two 

 paginations, one for the memoir, and the other for the volume : 

 by this arrangement memoirs cannot remain long unpubhshed, 

 and the memoirs will form a series of volumes. 



3. Statistical Societies in France. 



Two Statistical Societies have lately been established in 

 France, one by the celebrated C£Esar Moreau, in which we find 

 as members many of the higher ranks in Paris ; the other under 

 the direction and auspices of that active, enterprising, and ac- 

 complished person the Baron Ferrusac. The Society of Fer - 

 rusac is divided into seven sections. 1. Civil Arithmetic. 2. 

 Physical Geography, and Natural Resources of the Soil. 3. Po- 

 litical Geography, Public Works, &c. 4. Medical Topogra- 

 phy, Pubhc Salubrity, Charitable Institutions. 5. Agriculture 

 and Rural Economy. 6. Manufactural Industi-y. 7. Commerce. 

 The central commission is composed of G5 members, and the 

 whole Society already consists of 100 members. The Society 

 has had already six meetings. 



Observations on the Cause of the Spouting of Overflowing Wells 

 or Artesian Fountains. 



According to some philosophers, the theory of the spouting 

 waters of Artesian springs has been referred, sometimes to that 

 o^ jets (Teau, and sometimes to that of syphons, a bored well 

 being, as they say, only the second branch of a large syphon, 

 of which the first branch is the subterranean course, betAveen 

 impermeable strata, followed by the compressed waters coming 

 from a higher country than that in which the bored well has 

 l)een formed. 



According to others, such a well can only be considered as a 

 tube, which shows the pressure of water upon an earthy or stony 

 stratum, at which the bored well terminates.
