rare, and has often been fatal, from destroying the action of the heart. It is that 
in which an individual scarcely utters a word, and in which he exhibits extreme 
paleness. When an emotion is very intense, it seldom spends itself in idle words ; 
it absorbs too much of the mind to vent its indignation in momentary expres- 
sions ; and, instead of being a stimulant it becomes a sedative to the system. 
Lxpirations are not excited as in the preceding instance, but the person affected 
draws deep inspirations ; and these having the tendency to bring the blood te- 
wards the chest, they diminish the quantity in the face and surface of the body ; 
and the superabundance in the thorax quickly causes palpitation or syncope, from 
the-action of the heart being oppressed.” ——P. 337-339. 
Fear, on the contrary, is a depressing passion, characterized by 
deep inspirations. 
“ Inspirations have the tendency to bring the bleod towards the chest in 
greater quantity than usual, and, if we have a superabundance here, it is obvious 
that a diminution will occur in other situations ; and it is these modifications in 
its distribution that explain the paleness of the face, coldness of the extremities, 
end the oppression of the chest in fear.”,-P. 344. An illustration of this view 
is found in retracing the transactions or amusements of our juvenile years. 
“¢ On a winter evening, when assembled together to listen to the credulous ma= 
tron, who felt all she described, and whose stories, from their interest, suspended 
every faculty except attention, and obliterated every feeling save sympathy—the 
pale countenance, heaving chest, and palpitation of the heart, expressed suffix 
Gently well the depth of our sentiments, and indicated clearly the cause to which 
the effects were attributable, viz. the functional disorders of respiration. During 
the continuance of the interest, no shivering or coldness was felt ; but when we 
approached towards the close, when no further mystery remained to excite or abs 
sorb, the mind became susceptible of the sensation of cold.”—P. 346. 
Though published with a view to the improvement of the prac« 
tice of medicine, it will be evident, from the contracted examinae 
tion which we are permitted to present to our readers, that the 
work before us is not restrictively the property of the professional 
man. The second and concluding volume, which is in preparation, 
will, however, be devoted to more practical topics. If it were only 
on account of the interesting application of the many phenomena 
of life, which constantly come under the notice of the domestic 
circle,—a mode of elucidation which produces such a convincing 
effect in the plastic arguments of the leader of the phrenological 
sect,—we should, without hesitation, recommend to the man of 
general science the perusal of the new theory of Dr, Holland.

Tue domestic economy of Natural History, is a study which af 
fects individuals of every rank and capacity. The country clergy- 
man, the independent gentleman, the hunter, the farmer, the wife, 
in short, all those who are restrained to particular localities in the 
country, are alike alumni of the universal school of nature. The 
power of observation, and a taste for the manifestations of the Dei- 
~ ty, in his wonderful arrangement of things, are the only requisites 
for the accumulation of facts, valuable and new. Under such cir-
