are to be found at present only in the forms of higher classes of the same type for instance the so common in tbe of new york precisely resemble the forms of the and the are principally whose form is an early or one of our present species c there seems however to he not so much a weakness of animal life itself as of direction thus number of species is in many instances much greater than at present but their organization is lower their distribution not distinct the different types not ao definitely and their forms more and fantastic hence it is concluded that there is u manifest progress in the succession of beings on the surface of the in an increasing to the living and among the especially j in their resemblance to man this connection is to be sought in the view of the creator himself j whose aim in forming the earth in allowing it to undergo the successive changes which has pointed out and in creating all the different types of animals which have passed away was to introduce man upon the surface of our globe we must remark that the connection of plan throughout the animal kingdom has been made more prominent in our than it will he found in the work itself indeed after the importance given to a purely scientific principle in mr lectures we must confess ourselves somewhat pointed not to find it penetrating the details somewhat more of than it does here perhaps it will be said that this would not be advisable for a work intended for bat on the one hand ct are much easier and better learned when we have a principle to string them on and an interest is thus given to some who would not otherwise be attracted � on the other if students are to learn bj they may as well and better learn principles than bare ts as mere natural history the work before us has immense advantages over most similar ones in having been executed and by thoroughly scientific men and not by as is generally the case in some passages we trace the marks of a foreign indicating that they were conceived in another language from that in which they are written hence occasional for example p � wheat taken from the of egypt has been made to and grow in ome page life is made to consist in

somewhat delayed and therefore probably hurried at the close in this way are apt to show marks of haste as one of which we presume the very slight mention of mr e must be considered as if we are rightly informed the of a large part of the work is due to him this is doubtless owing merely to want of consideration of the force of phrases in this comparatively unimportant part of the work of slavery art iv � of slavery of the great which are now a the community not one deserves a more careful and earnest tion not one higher considerations of duty than does the of the united states when rightly interpreted support slavery we propose to consider question as briefly as is consistent with clearness of course only that slavery which is legal can be constitutional but it is argued that all slavery is law is defined to be a natural permanent principle any rule it is not existing in the nature of i or that is not permanent universal and in its application is no law the civil rights of men it is are defined by the and principle of natural justice justice must be either absolute or relative an absolutely just act is just at all times in all places and under all circumstances a just action is just only at some particular time and place and under me particular circumstances consequently the rule of relative justice is constantly changing with time place and therefore it cannot be on this theory therefore it cannot be law because law is law on this then must be with absolute justice without denying that it is possible for the human race ultimately to acquire a knowledge of the test of that which is absolutely just and right it is sufficient for the purposes of our argument that it is evident that no such test at present exists but if law is with absolute justice if we cannot tell what is absolute justice we cannot tell what is law and consequently not prove even slave holding to be but law is a practical science to remain so we cannot take our notions it seems to argue this point the author of this theory strangely enough admits the present non existence of a test of what is naturally just he says whenever the natural law is sufficiently certain to all men s minds to justify its being it is sufficiently certain to need no on the other hand ii be thus there is danger of doing by it it should be left open to be discussed by any body who may be disposed to question it and to be judged of by the proper the he therefore admits that in some cases we cannot now tell what natural justice demands of us but if we had a test of natural justice we could decide all cases of of relative justice as its test and declare not to be law every rule which we believe to be unjust
