 Tschugan.  These animals, which are  the .remote offspring of  
 domesticated  horses, now  differ from  the  Russian  breed  in  
 halving  larger  heads,  and  more  pointed  ears::  their mane is  
 short and  bristly, and their  tail  has »become  shorter.  Their  
 colour is said to be almost uniformly of a dun or brown;  Pied  
 and  black  horses  are  very  rare among  them.  Pallas adds,  
 th a t  their  principal  traits,  or  those  which distinguish  them  
 from domestic breeds of  the .horse kind,  and which  may  be  
 considered  as  characteristics  acquired  by the  stock  sincent  
 ran wild in  the desert areas follows:—they have larger heads  
 than  domestic  horses,  with  more  vaulted  foreheads ;  their  
 moiiths are more hairy,  and the  mane  comes down  lower on  
 the shoulders ; their limbs are  stronger, their back less arqhed  
 or vaulted;  their  hoofs are  smaller  and  more  pointed:ftheir  
 ears are longer and are bent forwards.*

 wild  stock  of  our  domestic oxeur  has the  fossa.lachrymalis  
 remarkably deep.  Our oxen have no traceo fit.-f 
 The  ffoat  exhibits  varieties  of  form.  There is  a breed of •  -•. -Ö       ..  ?" ;  _  ----  ^  . 
 goats near Jerusalem of various colours, black, white, and grey:;  
 the ears are remarkably long.  The goats of Aleppo are «of two  
 breeds ;  one is like the  English,  the  other  somewhat  larger,  
 with ears often a foot long, and broad in proportion.^ 
 No  animals  exhibit  greater diversity of form than  the  domestic  
 fowls.  “  Some  of  them,”  says  Pallas,  “  ate  Jarge, •*§

 received opinion, which makes the urus  or  aurochs  the  wild'representative  
 of our domestic »cattle, has lately been  controverted  by M.  Cuvier.  This  author  
 has described the fossil skull of  an animal of the  Ox tribe, which  he .conceives to  
 hove been the-true prototype of the domesticated breeds, and to havé become extinct  
 in its natural condition:  Tt differs considerably, according to Cuvier, from the skull  
 of the urus.  It appears that  the ancients were acquainted -with two wild animals of  
 this tribe ^ viz. the urus and the bison,_ and  that one Of  them has .perished.  Pliny  
 distinguishes them, and Seneca mentions them both in the following lines : 
 H Tibi dant variæ peetora tigres,, 
 Tibi villosi  terga bisontes, 
 Latisque feri cornibus uri.”— Seneca Hippol.

 some extremely  small; they  are tall, dwarfish;  have small, or  
 large and'dtnrble combs;  some have tufts of  feathers on their  
 heads; some have bare and yellow lègs;  others have their legs  
 covered with feathers.”  What is  still more remarkable, is that  
 there  is.  breed  without  rumps,  Corhmon  in  some  parts  of  
 England,  and another with^five  claws.  The  fowl  of  Padua,  
 of which Pallas  has published  an  account, has  a peculiarity  
 in the  conformation  and  capacity of the skull,- which is,  perhaps, 
   a greater deviation from  the  usual-  structure  than  any  
 other speciesfof  animal presents.* 
 The want of  horns is a character  some  breeds,  both  of  
 sheep and oxen :* the sheep of'"0rete and  Sicily,- and the oxen  
 of Abyssinia, present  a singular'contrast to these  ^breeds,  in  
 the-number or  enormous  «izèilaf  their  horaS..  In  Paraguay  
 there  are  breeds  of. oxen without horns, descended  from  the-  
 common  horned  race.  This  circumstance  is  remarked with  
 surprise  by/Azara,  who: contrasts  it. with a fact much  more  
 extraordinary, if true,  that the horses  in the same* country are  
 sometimes seen with horns. 
 If we  take a  collective  survey of  these diversities in the figure  
 ahd. proportions of parts, distinguishing particular breeds  
 in  the several  species  of  animals, we^diseover that the primitive  
 Hype4 is  stamped  upon each kind, with  a considerable allowance  
 for- the  origination  of  new varieties in form  and  organic  
 structures  The. deviations from  a  common  model  in  
 mankind  are  less* in 'degree-  than  those which  are found  in  
 many other  specie!,,and  they are in kind  analogous, as far as  
 such analogy can be expected.
