2. Number of Branches Five-——The number of branches from 
the arch five and classified according to their arrangement as fol- 
lows: 
(a) The order of branches is: Innominate, right vertebral, left 
carotid, left vertebral, left subclavian; see fig. 48. Cases are re- 
ported by Penada (1801), Fiorati (1805), Meckel (1805), Huber 
(Tiedemann, 1822). 
(b) The order of branches is: Innominate, composed of the 
right carotid and vertebral, left carotid, left vertebral, left sub- 
clavian, right subclavian. These cases are included in section I], 
D, 1, and are as follows: 
Tiedemann (1846) 2 cases, Bankart, Pye-Smith, Phillips (1869), Barkow 
(1869), Giacomini (1882), Brenner (1883), Shepherd (1890). 
(c) The order of branches is: Right subclavian, right caro- 
tid, left carotid, left vertebral, left subclavian. This condition 
has been reported by Petsche (1736) and Loder (1781). 
(d) The order of branches is: Right carotid, left carotid, left 
vertebral, left subclavian, right subclavian. These cases have 
been reported as a part of the list of section II, D, 1, classifying 
the low origin of the right subclavian. 
They are as follows: 
Koberwein (1810), Meckel (1820), Godman (1824), Hesselbach (1824), 
Quain (1844) 2 cases, Bankart, Pye-Smith, Phillips (1869), Pye-Smith, 
Howse, Davies, Colley (1871), McArdle (1885). 
(e) The order of branches is: Right carotid, left carotid, left 
subclavian, left vertebral, right subclavian. This is similar to the 
last group, except that the left vertebral follows the left subclavian 
on the arch; a case has been reported by Wagner (1828). 
(f) The order of branches is: Innominate, right internal mam- 
mary, left carotid, left vertebral, left subclavian. Cases have 
been reported by Casselbohm (Bohmer, 1741) and Meckel (1816). 
(g) Ina right arch the order of branches is: Left carotid, right 
carotid, right vertebral, right subclavian, left subclavian. Cases
