coloured, and the lead-coloured, of large size, in the moist 
grounds under the oak and beech | woods. I have also noticed a 
plentiful crop of the following species : 
Agaricus Slaccosus, the rough, tawny-yellow agarick, at the 
root of apple-trees in the orchard. 
Agaricus denticulatus, in the long grass. 
Agaricus glutinosus, in the same place, but more sparingly. 
Agaricus stercorarius, numerous and remarkably beautiful 
specimens in the dung of horses in the fields. 
Agaricus fascicular is. This species came up early even during 
the dry weather, and is still abundant, but not particularly large. 
The Boletus bovinus as well as another Boletus (which, whe- 
ther it be a variety of Lovins or not I am uncertain) have grown 
to an enormous bigness. Some have weighed above four pounds, 
and the diameter of their pilei was above fourteen inches. Se- 
veral other Boleti are also abundant and of large growth. But 
unfortunately, owing to the imperfect nomenciature and arrange- 
ment of fungi yet extant, many species of Boletus as well as of 
Agaricus which grow here, cannot be identified. Mr. Sowerby’s 
work constitutes a most interesting and useful sylva fungorum, 
wherein the botanist may study and arrange most of the British 
species, but they have never yet been accurately described. 
The most beautiful species we have here is the Agaricus pli- 
catilis. The genus Pexiza has been rather scarce this year.—I 
am induced to think that the most fruitful sort of season in fungi 
is one where a hot and dry summer is succeeded by a moderately 
wet antumn ; as by looking back in my Journals I find this fre- 
quently to have been the case, while the wholly wet summers and 
autumns have been less productive. 
[ shall prepare for some future number a table of observations 
for about nineteen years past, compared with weather and other 
collateral phenomena. Yours, &c.

Dn. SPURZHEIM has just published a new work on the Physi- 
ology of the Brain, entitled Olservations sur la Phraenologie: 
in which he has, in some measure, improved on the arrangement 
of the organs. He admits now the existence of 35 separate or- 
gans in the brain; among them is the convolution called by Dr.. 
Foreter, Organ af superstitiousness or mystery. The work is 
published at Strasburgh, Paris, and London. 
Dr. Gall has likewise published another splendid folio fasci- 
culus of plates of the brain, accompanied by descriptions and 
an elucidation of his doctrine,
