    This mixture retains its fluidity, when melted, for a long time, and may be thrown from the arch of the aorta through the primitive and many of the secondary arterial trunks, without heating the subject. Its cheap- ness makes it very advantageous. The success of this injection will be increased by throwing in first, a syringe full of Nos. IV. or V. pro- perly heated, with a view of warming somewhat the vessels and removing their rigidity. In the use of these formulae, excepting Nos. VII. VIII. and IX., it is indispensable to warm the subject thoroughly by previous immersion in water hot enough to excite the sensation of scalding in the finger. If the water be warmer, it will cause the parts to contract and become rigid instead of softening them. The in- jections must be of a proportionate temperature. The more limited the range of an injection is, the more likely it will be to succeed well, as the force of the syringe is thereby concentrated. Hence a rule is established to put the pipe as near as possible to the part intended to be injected. No. I. is used for corroded and dried preparations. Nos. II. and III. for the latter alone. Nos. IV. and V. are sometimes used as the precursor to the three first. No. VI. is adopted in wet preparations and such as are
