irculatory, (c) the excretory, and
(d) the reproductive organs of the amphioxus.
2. Describe the stomach and intestines of the dog-fish and rabbit, and
point out in what way their differences are connected with diet.
3. Describe the mechanism of respiration in the adult frog, and
contrast it with that of the tadpole.
4. Give an account of the structure of the epidermis and its
outgrowths in the frog and the rabbit.
5. Describe the organs of circulation (heart and main arteries and
veins) and respiration in the frog in its mature and immature states.
6. Give a brief account of the physiology of respiration. Describe fully
the means by which respiration is effected in the following animals:--
frog, amphioxus, rabbit, and dog-fish.
7. Describe the minute structure of the blood of the rabbit, frog, and
amphioxus.
8. Describe and illustrate by means of sketches the chief points of
difference between the skeleton of the rabbit as a typical mammal,
and that of the common frog as a typical amphibian.
9. (a) Explain what is meant by the term "central nervous system."
(b) Describe the tissue elements which enter into its composition.
(c) Explain, as far as you can, the function of each structure
described. (d) How is the central nervous system developed in the
frog, and (e) in the rabbit? (f) What conclusions may be drawn from
the facts stated as to the origin of the central nervous system in
evolution?
10. Give an account of the structure (including histology) and of the
functions of the spinal cord and spinal nerves of the frog.
11. Give a description of the minute structure and chemical
characters of the following tissues as seen in the frog:-- cartilage,
bone, muscle. From which of the primary cell-layers of the embryo are
they respectively developed?
12. What substance is excreted by the renal organ of a frog, and what
relation does this substance bear to the general life of the organism?
Describe the parts by which similar excretion is believed to be
effected in amoeba, hydra, earthworm, mussel, and lobster.
13. Describe, with illustrative sketches, the structure of the connective
tissue, cartilage, and muscular tissue of a frog. Also describe the
structure of the muscular tissue of the lobster and snail.
14. Give in account of the more important features in the
development of the frog.
15. Describe and compare the structure of the renal organs in a frog
and a rabbit.
16. Give an account o
