percentage calculations become very considerable. It is true he may be aided by 
certain existing tables for ready-reckoning, but these apply to only a limited 
number of the possible combinations of figures which he has to deal with. 
Indeed, if records are made in numbers of only three figures, it will readily be 
perceived that the possible combinations of actual and average numbers amount to 
hundreds of thousands, 
The diagrammatic method which the author’s own wants have led him to 
attempt, may be briefly explained by the following directions for constructing a 
diagram. Take a sheet of ‘quad ’-ruled paper—that is, of paper evenly divided into 
minute squares. Then on its horizontal lines mark off a scale of numbers having 
any convenient range, say from 150 below to 300 aboye. Call this the 
‘horizontal scale.’ Next traverse this scale by an cblique ‘percentage scale,’ 
whose lines may conveniently be of a different appearance—for instance, of a red 
colour. To construct this percentage scale, first rule a 100 per cent., or ‘ par’ 
line, beginning from 150 on the left of the horizontal scale and sloping up to 300 
on its right. Number it as 100 at both ends, say, in red figures, Then fill in 
other oblique red lines to form the percentage scale. Construct, for instance, a 
+10 per-cent. oblique line, beginning on the left of the horizontal scale at 150+ 10 
per cent. (= 165), and reaching on its right to 300+ 10 per cent. (=830). Then, 
if the ruling have been accurately done, it will appear that at every inter- 
mediate point, this +10 per cent. (red) line has its course 10 per cent. higher than ; 
any number on the 100 per-cent. line—that is, 10 per cent. above any number 
between 150 and 300. Similarly construct oblique lines for all convenient pers 
canes above or below the 100 per-cent. line, and so complete the percentage 
scale, 
The range of 150 to 300 as a 100 per-cent. line has been taken as an instance, 
but the method may, by the use of several diagram sheets, be readily applied to 
all numbers up to, say, 1,000 and its percentages. A leading method of employ- 
ing such diagrams is (a) to find on the 100 per-cent line the position of any 
average number required ; (4) to keep by means of a ‘ set-square’ the vertical line 
of that number; (c) to find on the horizontal scale the actual number to be com, 
pared; (d) to keep the horizontal line of that number; (e) to note the intersecting 
point of such vertical and horizontal lines, and at that point to read off on the per- 
centage (red) scale the percentage relation of the two numbers. Amongst other 
uses may be obviously that of ascertaining the percentage relation or ‘index’ of two 
diameters, for instance, of different parts of the human head, trunk, or limbs, but 
particularly any diameters which do not fall within existing published tables,

7. Notes on Human Remains discovered by General Pitt-Rivers at Wood- 
yates, Wiltshire. By J. G. Garson, M.D., V.P. Anthrop. Inst. 
The author described a series of human osteological remains discovered by 
General Pitt-Rivers near Woodyates during the last two years, which, through the 
kindness of General Pitt-Rivers, he had an opportunity of examining. The data 
for the communication were drawn from his own observations and from the 
measurements of the skulls and other bones of the skeleton, made by General Pitt- 
Rivers and placed at his disposal for the purpose. 
General Pitt-Rivers’s measurements of the limb bones showed the stature of the 
individuals to have been greater than that of the persons who were interred in 
Woodcuts and Rotherley, Romano-British villages, described by General Pitt- 
Rivers in his works on these settlements. 
The characters of the skulls showed a considerable range of variation in size 
and proportion, indicating that they did not belong to a homogeneous race, but to 
individuals of mixed race. Variation was found, not only in the facial portion,
