VARIATIONS IN THE CEREBRAL FORMS AND FissuRLs VI
DOMESTIC DoGs.-BY BURT @. WILDER.
Tho tooUiug observations are based upon the carefu
studv OF q dogs BRAINS representing Is breeds There
vera four of the same family mother ana three emil
dren OF different ages; two others nearly related 10
them and pair brothers Of different ages the Others
are not known be reated most OF them are
mining the homologous assures, do not forget tnaS
the sheets Of gray matter are IN themselves piy
cies but would be hard to designate ious Wtnou
first identifying assures TO describe the countries OF
Europe without mentioning ITS rivers MoreG ,n Se
yening fssure, may in another be one cOntnuous Iou
what shall 1t be caledi Granting them that ods are ire
SO thoroughly identified in all animals tnat when one vi
them Of the folds is mentioned there can pe no
doubt of its being recognized by all.
The following are merely general statelhonVSo VI laws
obvious from the diagrams exhibited:

which do not affect tho presence relative position OF
main assures. but their length direction branches con-
pecons and continuity, aud, by inference, the manner
OF their formation, which enable us TO recognize any
brain thereby and which may in some cases approx
mate them TO other carniyor0us families.
s. There are minor resembances between brains OF the
same family and breed which lead us to infer ne exs
ence uniform modification OF the general pattern lor
a. The two sides of the same brain present just such
variations as those above described between dnereht
Since no two brains of different species can be 80
nearly related two halves OF the same BRAIN rs
evident that careful study OF lateral variation WIZ
furnish test of the value OF the dherentGs r Un
or descriptions OF both sides of the same brain. l.,
s. Lateral variation Is often compensatory: P1r M h

being equal to the single one; straight nss1re may
represent a curved one; or single one may nave as
counterpart shorter one with branch IN one case

EVEN DISTRIBUTION OF FIssUREs.
c. As TO the distribution OF hssures can merely
express my conviction that at least one OF the elements
of the ssura pattern is the subdivision OF the surface
into approximately equal shall endesVor mere
after to demonstrate this by photographng the surface
Of hemisphere previously spread upon plane. NOW
IL the idea prove correct IL will form strong argument
IN favor OF view that each cerebral mass Is SIN
Gle organ in structure and function its energy LOT any
required manifestation being III proportion 10 the mum
Der and depth of the assures, other things OF course
being equal namely, the thickness OF the gahghomo
stratum, and It's quality" III. -.
y The domestic dogs have all moro compexitY OF
assures than the fera canid8 lfoX wolf, ana weaseD'
but the assures of the young lion are vastly more nuher
ous and complex than those Of any adult cat: PfOi
Agasslz suggests that the greater cerebral power
indicated by the condition OF the lions ceTeOrum may
be connected with its prodigOus virity the complete
sexual having been performed nine tunes IN an hOr
under his Obserya On and the same rate having Deth
maintained during at least two successive nights III is
probable that we must regard the cerebral mass "a
capable of expendng force in three directions
which are ideally distinct at least IN their PURPOSE Dul
practically linked together in most cases
j. peysGa' for the individual
g. Sexual. for the species
At present we have way OF ascertaining from the
brain alone whether It's pecularles relate ~ greater
mental, ply steal, sexual power.
The absolute weights of brain ana Its ratio IN
thOusandths the whole body, Is mainly connrmatory
OF general rule that young mammals have proper
tonay larger brans and that the smaller species and
varieties like excel the larger but the differ
ence between instance little tan terrier and New
fOundland is something prodgious.
