Describe the mechanism of respiration. What is the relation of
respiration to the general life of the animal?

35. What are the functions of the skin? Describe its structure.

36. What is a secretion? Tabulate and classify secretary organs.
What is a goblet cell?

37. Draw, from memory, the dorsal and ventral aspects of, and a
median section through, a dog's skull.

38. Name any structures that appear to you to be vestiges or
rudiments, i.e., structures without adequate physiological reason, in
the rabbit's anatomy.

39. How are such structures interpreted?

40. Describe the structure of striated muscular fibre. Describe its
functions, and the various means by which they may be called into
activity.

41. Describe the characters and structure of the blood of the rabbit.
What is the lymphatic system? Describe its relation to the blood
system in a mammal.

42. Describe the structure of (a) blood, (b) hyaline cartilage, (c)
bone, in the rabbit; (d) point out the most important resemblances and
differences between these tissues; (e) state what you know of the
development of the same tissues.

43. Draw diagrams, with the parts named, of the male and female
generative organs of the rabbit.

44. In the rabbit provided dissect on one side and demonstrate by
means of flag-labels the main trunk of the vagus nerve, the phrenic
nerve, and the recurrent laryngeal nerve.

45. Dissect the rabbit provided so as to expose the abdominal
viscera. Mark with flag-labels the duct of the pancreas, the ureters,
and the oviducts or the sperm ducts (as the case may be).

-The Frog_

1. _General Anatomy_

Section 1. We will now study the adult anatomy of the frog, and
throughout we shall make constant comparisons with that of the
rabbit. In the rabbit we have a distinctly land-loving, burrowing animal;
it eats purely vegetable food, and drinks but little. In the frog we have
a mainly insectivorous type, living much in the water. This involves the
moister skin, the shorter alimentary canal, and the abbreviated neck
(Rabbit, Section 2) of the frog; the tail is absent-- in a fish it would do
the work the frog accomplishes with his hind legs-- and the apertures
which are posterior in the rabbit, run together into one dorsal opening,
the cloaca. There is, of course (Rabbit, Section 4), no hair the skin is
