COMPARATIVE ANATOMY.
T. K. ROGERS, M.B., F.R.C.S.

1. Give a brief account of the Rhizohoda.

II. Supposing the skull of a vertebrate animal to be placed in your hands, to what points would you direct your attention, for the purpose of ascertaining the Order to which the animal had belong. ed?

III. Define the meaning of the terms, Homologous and Analo. gous; and illustrate your explanations by means of examples.

IV. Describe the various means by which Reproduction is effected in the Animal Kingdom; giving examples of each method. V. Give an account of the Polyzoa.

What other groups of animals are most nearly allied to them ? VI. Describe the chief modifications in the structure of the heart, and the arrangement of the great blood vessels, met with amongst vertebrate animals.

VII. To what class does the common Star Fish belong? Give an account of its locomotor organs,

B. C. E. DEGREE EXAMINATION, 1879.

MONDAY, 10TH FEB., 10 A.M. TO 1 P.M.
SURVEYING AND LEVELLING.

CAPTAIN W. H. COAKER, R.E.

I. On a Russian map a distance of 43 versts is found to measure 3.4 inches. Draw a comparative scale of English miles, shew.. ing furlongs diagonally, and write down the representative fraction of the scale.

(One verst 1166.6 English yards). II. The vertical arc of an Everest theodolite is graduated to one-third degrees. Shew how to attach a vernier to read minutes in both directions, and note the reading shewn.

(The scale may be drawn straight). III. What is meant by the variation of the compass ? Describe any simple method of ascertaining it.

IV. Explain the principle of construction of the box sestant, and show how to find the index error.

V. Name, without describing, the permanent adjustments of Everest's double arc theodolite, and state the bject of each. Which of these are absolutely necessary, and how would you observe correctly without making the other adjustments ?

VI. How would you observe a horizontal angle with (1) the prismatic compass, (2) the sextant, (3) the theodolite ?

VII. Detail the operations in making a survey for a new road, and state what information should be recorded in your note-book.

VIII. A curve with a radius of a quarter of a mile is 1,000 feet long. Find the length of the tangents and their angle of intersection. Make the necessary calculation for laying it out by tan. gential angles, and prove that all the points obtained by this method lie in the circumference of the circle.

IX. Describe the method of finding heights by the aneroid barometer, and write down a simple formula for the purpose.

MONDAY, 10TH FEB., 2 to 4 P.M.
SURVEYING AND LEVELLING.

CAPTAIN W. H. COAKER, R.E.

I. Reduce the field book shown in the Diagram (A), and plot the section to scales of

200 feet to an inch horizontal,
20

vertical.

Lay down on the section the gradients you would propose for

a first class road, and mark in figures the rate of inclina.

tion of each gradient. II. Plot by the method of rectangular co-ordinates the polygon ABCDE to a scale of 200 feet to an inch, from the following data:

[merged small][merged small][merged small][merged small][merged small][ocr errors]
[blocks in formation]

530

870 1,407 1,110 872

[blocks in formation]

I. A girder 40 feet long is loaded at points A, B, O, D., distant 5, 15, 24, and 32 feet from one end, with weights of 4, 12, 10, and 15 tons respectively. Draw the polygon of bending moments, and find what weights must be added at B in order to make the bending moments at B and C equal.
