indicate instinct, that is to say, the spirit of self-preservation. 
In the fourth, will, or more correctly, intelligence, begins to 
develop itself. But in the fifth, composed of the human race, 
appear free-will, reflection, imagination, and above all, the 
spirit of perfection, which is not found in any other class. 
These progressive degrees are completely indicated by the 
greater or less development of the nervous system. A work 
on the comparative researches into that system, and which 
supplies rules for classification, was lately given me by Signor 
Bazin, entitled “ Del Sistema Nervoso, della vita Animale e 
delle vita Vegetabiley These are subjects, on which, as all 
must see, an hasty opinion cannot be given. 
SPAIN. 
The Spanish disturbances do not, as yet, permit that nation 
to employ itself successfully on studies which require peace 
and quiet. It is however known, that in certain provinces, 
especially in Catalonia, new museums are being erected, and 
that the Academies are beginning to flourish again, two of 
which, that of Madrid and of Barcelona, w e have the pleasure 
to see here represented. 
PORTUGAL. 
Portugal, of which I might repeat the above remark, has 
suffered, besides a great loss in the Prince Augustus of Leuch- 
temberg, the first husband of the Queen, an excellent friend 
and patron of the unfortunate Wagler. So great w^ere his 
aims, and his noble intentions for the promotion of natural 
science, which he cultivated and loved beyond all others, as I 
could show to you by the epistolary correspondence with which 
my noble relation favoured me.
