The breadth of the middle parastae (EF and HG) is one hole and TK, the thickness one 
hole ; the interval where the arrow is placed between the middle parastæ is the fourth part 
of a hole. The four angles that are on the sides and fronts are secured with iron plates, or 
brass bars and nails. 
The length of the canalicule (CC, Fig. XCI.), which in Greek is called strix, is XIX. holes. 
The regulæ (BB), which some call bucculae, that are fixed on the right and left of the channel, 
are XIX. holes; the height and thicknes one hole: also two regulæ (FE. Fig. XCVII.) are 
affixed, in which is inserted the sucula (EE), being three holes in length, and half a hole in 
breadth. The thickness of the buccula that is affixed, called camillum, or, according to some, 
loculamentum, being fixed with a dovetail tenon, is I. hole, the height S. of a hole. The 
sucula is in length :: holes :::. The thickness of the scutula is IX. holes. The epitoxis (GG) 
is in length S:—: holes ; in thickness:—. Also the chelo (cheira), or manucla (I, Fig. XCII.), 
as it is called, is in length III. holes, in breadth and thicknes S.—: The length of the fundus 
of the channel is XVI. holes, the thickness a hole ::, the breadth S:— 
The columella and base on the ground is VIII. holes; the breadth in the plinth in which the 
columella is fixed up, is S:— The thickness F. Z. The length of the columella to the tenons 
is XII, holes :: ; the breadth S:— of a hole. The thickness U.9 ; its three capreals (braces) 
are in length IX. holes, in breadth half of a hole ::, in thicknefs Z. The length of the cardo 
Ltenon) a hole:. The lengch of the head of the columella I. S. K, the breadth of the 
anteßra S. :: 9. of a hole, the thicknes I. The posterior smaller column, which in Greck is 
called antibafs, is VII. holes; the breadth S. L. of a hole, the thicknes F. Z. The jatgjecio is 
XII holes, the breadth and thickness is the same as that of the smaller column. The chelorium, 
or pulvinus, as it is called, upon the fmaller column, is II. S. :; the hejght Il. 8. 3 
(4*) Some commentators allege hrinx should be here 
vritten instead of stris; the former being the Greek name 
of a pipe. Heron uses the term jrinz, as appears by the 
foregoing description of the catapulta. But it may be 
observed that the thing here spoken of, is a channel, not 
a pipe; and that Vitruvius, ch. ii. b. iv. has applied the 
term strix to the channel of a column. I have therefore 
left the word as in the text. 
(5*) The number specitying the length of the Jacula 
is wanting in all the copies. Galiani taking it from Cela¬ 
riani, has added VI. S. eigbt and a balf, for its length; 
and Barbaro, with Perrault, nine. But the length of the 
sucula has just before been said to be three holes; from 
whence I imagine that scutula has been here originally 
written, especially as the thickness of that part imme- 
diately follows. 
(65) Canalis fundi is rendered by the translators the 
bottom of the channel, and the channel of the bottom: but as, 
at the 13th chap. preceding, the term fundus is several 
times used for the stoppers or sliders that move in the 
buckets or modiols, it appears to me probable that the 
word fundus is used as a technical term in this place, 
and signifies something of the same kind. The epitoxis 
is the part GG, Fig. XCII.; and the chelo or manucla seems 
to be that called cheira or band by the Greeks. At the 18th 
chapter sollowing, the cheeks on each side the cheira are 
called chelonia.
