Anæsthesia ensues in from six to twenty minutes, and if the cause of the
lameness is below the point of injection the animal moves sound.

Regarding this method of diagnosis, Professor Udriski of Bucharest, after a
series of trials, sums up as follows:

1. For the diagnosis of lameness cocaine injections are of very
considerable value.

2. These injections should be made along the course of the nerves.

3. Solutions heated to 40° or 50° C. produced quicker, deeper, and longer
anæsthesia than equally strong cold solutions.

4. In the sale of horses cocaine injections conceal fraud.

Cocaine being an irritant, it must be remembered that after the anæsthesia
the lameness is somewhat more marked than before.

To the cocaine other practitioners add morphia in the following
proportions:

Cocaine hydrochlorate 2-1/2 grains.
Morphia 1-1/2 "
Aqua destil 1-1/2 drams.

As a diagnostic this mixture of the two is said to be far superior to
either cocaine or morphia alone.
