Meteorology of the Pic du Midi, given in Dr. 

 Brewster's Edinburgh Journal of Science, No. 

 IX. p. 180; in which it is stated, that " when 

 M. Ramond was on the Pic du Midi, he ob- 

 served his own shadow, and those of his two 

 companions, projected on a cloud, situated a 

 little distance above them, with a distinctness, 

 and an accuracy of outline, quite surprising; 

 but what was more astonishing, these shadows 

 were encircled with glories, shining with the 

 most brilliant colours." 



" M. Ramond considers it as certain, that the 

 cloud on which his shadow was projected could 

 not, from the temperature of the Pic, have then 

 held any icy particles in suspension." — It does 

 not appear, however, that he ascertained the 

 temperature of the cloud itself; indeed, as his 

 inference, that it did not contain any frozen par- 

 ticles, seems to have been deduced solely from 

 the temperature of the Pic, it may be presumed, 

 that he did not determine it experimentally ; but, 

 as I have had no opportunity of consulting his 

 essay, I cannot positively affirm that this was 

 the case. 



There exists a possibility, therefore, that, in 

 the demonstration of this interesting fact, I may 

 have been anticipated ; still it is one of so ijiuch
