d which may be used as
opportunity allows to supplement those already given.

Experiment 193. _To examine white fibrous tissue._ Snip off a very
minute portion from the muscle of a rabbit, or any small animal recently
dead. Tease the specimen with needles, mount in salt solution and
examine under a high power. Note the course and characters of the
fibers.

Experiment 194. _To examine elastic tissue._ Tease out a small
piece of ligament from a rabbit's leg in salt solution; mount in the
same, and examine as before. Note the curled elastic fibers.

Experiment 195. _To examine areolar tissue._ Gently tease apart
some muscular fibers, noting that they are attached to each other by
connective tissue. Remove a little of this tissue to a slide and examine
as before. Examine the matrix with curled elastic fiber mixed with
straight white fibers.

Experiment 196. _To examine adipose tissue._ Take a bit of fat from
the mesentery of a rabbit. Tease the specimen in salt solution and mount
in the same. Note the fat cells lying in a vascular meshwork.

Experiment 197. _To examine connective tissues._ Take a very small
portion from one of the tendons of a rabbit, or any animal recently
dead; place upon a glass slide with a drop of salt solution; tease it
apart with needles, cover with thin glass and examine with microscope.
The fine wavy filaments will be seen. Allow a drop of dilute acetic acid
to run under the cover glass; the filaments will swell and become
transparent.

Experiment 198. Tease out a small piece of ligament from the
rabbit's leg in salt solution; mount in the same, and examine under a
high power. Note the curled elastic fibers.

Experiment 199. _A crude experiment to represent the way in which a
person's neck is broken._ Bring the ends of the left thumb and the left
second finger together in the form of a ring. Place a piece of a wooden
toothpick across it from the middle of the finger to the middle of the
thumb. Put the right forefinger of the other hand up through the front
part to represent the odontoid process of the axis, and place some
absorbent cotton through the other part to represent the spinal cord.
Push backwards with the forefinger with just enough force to break the
toothpick and drive its fragments on to the cotton.

Experiment 200. _To illustrate how the pulse-wave is transmitted
along an artery._ Use the same apparatus
