EXAMINATION IN MENSURATION AND LAND SURVEYING. 
Maximum Number of Marks, 103. Pass Number, 40. 
Wednesday, November 8, 1893. 
{Two hours allowed.) 
1. The sides of a quadrilateral figure, taken in order, are 310, 196, 283, 415 ft. 
respectively; the angle between the first and fourth sides is 72°; draw the 
figure to a scale of 1 in. equal to <55 ft., and note the number of degrees in the 
angle opposite to the given angle, and the number of feet in the diagonal 
passing through the given angle. 
2. The dimensions of a brick set in mortar are 9 in. by 4| in. by 3 in. ; 
find how many bricks are required to build a mass of brickwork 10 ft. by 8 ft. 
by 4| ft. 
a: A cylindrical tank is 12 ft. high, and the diameter of its base is 9 ft. ; 
given that 25 gallons equal 4 cubic feet, find the number of gallons that the 
tank will contain. 
4. Briefly explain the principle of the vernier. 
Draw a line 3 in. long, and divide it into inches and tenths of an inch, 
and mark the inches 0, 1, 2, 3 ; draw a vernier by which the scale can be 
read to one-hundredth of an inch, and draw the vernier against the scale in 
the position it would occupy when the reading is 137 in. 
5. Along a line AB beginning from A, distances 0, 105, 220, 350, 410, 480, 
575, 750 are measured ; the offsets at the points respectively are 0, 80, 60, 40, 0 
to the right, and 70, 90, 50 to the left, all being in links. Arrange these 
measurements in the form in which they would be entered in a field-book, and 
plot the boundary to a scale 1 in. equal to 1 chain. 
6. A, B, C, are three points on the ground, not in the same straight line. 
A level is placed between A and B, and the readings are 2 35 back-sight to A, 
and 6'60 fore-sight to B ; it is then placed between B and C, and the readings 
are 4 71 back-sight to B, and 7 - 58 fore-sight to C ; if the level is now placed 
between C and A, and the fore-sight to A is 317, what should the back-sight 
to C be? 
ANNUAL REPORT FOR 1893 OF THE 
CONSULTING CHEMIST. 
During the twelve months ended November 30, 1893, the number 
of samples submitted to me for analysis in the ordinary course by 
Members of the Society has been 1,363, this being 152 in excess of 
the number sent during the previous year, 1891-2. In addition, 
there have been a number of samples analysed in connection with 
the Society’s Experimental Farm at Woburn, others in connection 
with the Country Meeting of the Society at Chester, and yet others 
relating to various matters of agricultural investigation — making alto- 
gether a total of 1,500 samples for the year. A list of the various 
heads under which the analyses have been grouped is given at the 
end of this report. 
The increase, while due in some measure to the larger exercise 
by Members of their privileges, is also due to the examination of 
some 80 samples on behalf of a Member who is carrying out various
