commerce of Europe； and the Chinese for that of Asia； they confine the factors and sailors in a kind of prison； and lay such a restraint upon them as tires their patience。
10。 In Russia the taxes are but small； they have been increased since the despotic power of the prince is exercised with more moderation。 See the History of the Tartars； part II。
11。 The Pays d'etats； where the states of the province assemble to deliberate on public affairs。
12。 This is the practice of the emperors of China。
13。 See in history the greatness； the oddity； and even the folly of those taxes。 Anastasius invented a tax for breathing； ut quisque pro haustu ？ris penderet。
14。 True it is that this state of effort is the chief support of the balance； because it checks the great powers。
15。 All that is wanting for this is to improve the new invention of the militia established in most parts of Europe； and carry it to the same excess as they do the regular troops。

Book XIV。 Of Laws in Relation to the Nature of the Climate
1。 General Idea。 If it be true that the temper of the mind and the passions of the heart are extremely different in different climates； the laws ought to be in relation both to the variety of those passions and to the variety of those tempers。
2。 Of the Difference of Men in different Climates。 Cold air constringes the extremities of the external fibres of the body；＇1＇ this increases their elasticity； and favours the return of the blood from the extreme parts to the heart。 It contracts＇2＇ those very fibres； consequently it increases also their force。 On the contrary； warm air relaxes and lengthens the extremes of the fibres； of course it diminishes their force and elasticity。
People are therefore more vigorous in cold climates。 Here the action of the heart and the reaction of the extremities of the fibres are better performed； the temperature of the humours is greater； the blood moves more freely towards the heart； and reciprocally the heart has more power。 This superiority of strength must produce various effects； for instance； a greater boldness； that is； more courage； a greater sense of superiority； that is； less desire of revenge； a greater opinion of security； that is； more frankness； less suspicion； policy； and cunning。 In short； this must be productive of very different tempers。 Put a man into a close； warm place； and for the reasons above given he will feel a great faintness。 If under this circumstance you propose a bold enterprise to him； I believe you will find him very little disposed towards it； his present weakness will throw him into despondency； he will be afraid of everything； being in a state of total incapacity。 The inhabitants of warm countries are； like old men； timorous； the people in cold countries are； like young men； brave。 If we reflect on the late wars；＇3＇ which are more recent in our memory； and in which we can better distinguish some particular effects that escape us at a greater distance of time； we shall find that the northern people； transplanted into southern regions；＇4＇ did not perform such exploits as their countrymen who； fighting in their own climate； possessed their full vigour and courage。
This strength of the fibres in northern nations is the cause that the coarser juices are extracted from their aliments。 Hence two things result： one； that the parts of the chyle or lymph are more proper； by reason of their large surface； to be applied to and to nourish the fibres； the other； that they are less proper； from their coarseness； to give a certain subtilty to the nervous juice。 Those people have therefore large bodies and but little vivacity。
The nerves that terminate from all parts in the cutis form each a nervous bundle； generally speaking； the whole nerve is not moved； but a very minute part。 In warm climates； where the cutis is relaxed； the ends of the nerves are expanded and laid open to the weakest action of the smallest objects。 In cold countries the cutis is constinged and the papill？ compressed： the miliary glands are in some measure paralytic； and the sensation does not reach the brain； except when it is very strong and proceeds from the whole nerve at once。 Now； imagination； taste； sensibility； and vivacity depend on an infinite number of small sensations。
I have observed the outermost part of a sheep's tongue； where； to the naked eye； it seems covered with papill？。 On these papill？ I have discerned through a microscope small hairs； or a kind of down； between the papill？ were pyramids shaped towards the ends like pincers。 Very likely these pyramids are the principal organ of taste。
I caused the half of this tongue to be frozen； and； observing it with the naked eye； I found the papill？ considerably diminished： even some rows of them were sunk into their sheath。 The outermost part I examined with the microscope； and perceived no pyramids。 In proportion as the frost went off； the papill？ seemed to the naked eye to rise； and with the microscope the miliary glands began to appear。
This observation confirms what I have been saying； that in cold countries the nervous glands are less expanded： they sink deeper into their sheaths； or they are sheltered from the action of external objects； consequently they have not such lively sensations。
In cold countries they have very little sensibility tor pleasure； in temperate countries； they have more； in warm countries； their sensibility is exquisite。 As climates are distinguished by degrees of latitude； we might distinguish them also in some measure by those of sensibility。 I have been at the opera in England and in Italy； where I have seen the same pieces and the same performers： and yet the same music produces such different effects on the two nations： one is so cold and phlegmatic； and the other so lively and enraptured； that it seems almost inconceivable。
It is the same with regard to pain； which is excited by the laceration of some fibre of the body。 The Author of nature has made it an established rule that this pain should be more acute in proportion as the laceration is greater： now it is evident that the large bodies and coarse fibres of the people of the north are less capable of laceration than the delicate fibres of the inhabitants of warm countries； consequently the soul is there less sensible of pain。 You must flay a Muscovite alive to make him feel。
From this delicacy of organs peculiar to warm climates it follows that the soul is most sensibly moved by whatever relates to the union of the two sexes： here everything leads to this object。
In northern climates scarcely has the animal part of love a power of making itself felt。 In tempe
