“In the cantons of Ploudalmézeau and of St. Renan, 
the monuments are generally simple ; seven menhirs 
_ are visible of enormous dimensions, remarkable by the 
polish of their surface and the regularity of their section. 
The roughnesses hardly ever reach a centimetre ; the 
sections are more often ovals, sometimes rectangles with 
the angles rounded or terminated by 
semicircles. In the canton of Crozon 
the monuments are, on the contrary, - ene 
complex ; we find a cromlech with an 
avenue leading to it of a length of 
800 metres, another of 300 metres. 
Unfortunately, the rocks employed 
(sandstone and schist from Plungastel 
and Crozon) have resisted less well 
than the granulite from the north 
part of the Department. The monu- 
ments are for the most part in a very 
bad condition; the whole must, 
nevertheless, formerly have been 
comparable with that of Carnac- 
Leomariaquer. ; 
“For the two regions, granitic and 
schistose, the results of the observa- 
* tions are identical.

determined for the solstices are much less so for the

very rapidly at this time of year.
