Excerpt: ... CHAPTER IIT. OF SOLUTIONS OF OXYMURIATE OF MERCURY. In using solutions of oxymuriate of mercury for anatomical preparations, it must always be kept in mind that unless animal substances are entirely changed, it must not be expected they will either be preserved from putrefaction or retain the properties of preparations made according to the rules which will be laid down. When this solution was first used for preparations, the animal bodies were not submitted to its influence for more than a few days; and the consequence was, that when they had been kept for some time in a damp place, all the deeper seated parts emitted an offensive smell, or became mouldy, and had a very different appearance from the superficial ones. Solution of Oxymuriate of Mercury in Water. Take of oxymuriate of mercury, one ounce. Muriate of ammonia, thirty-five grains. Water, one pint. The oxymuriate of mercury and muriate of ammonia must be rubbed together in a mortar, and then the water must be added gradually until the solution is complete. Though this solution no longer contains oxymuriate of mercury in the same state as when dissolved in alcohol, yet it has the effect of hardening animal bodies in the same manner. I have supposed that preparations made with this solution might be more liable to be affected by damp air on account of the addition of muriate of ammonia, but from the appearance of those made several years ago it is not probable that any injury of this sort will be sustained. A white precipitate is thrown down during the time an animal body is immersed in it, and should occasionally be removed, for if it be suffered to collect at the bottom of the box it prevents the free access of the solution to the subject, and then the necessary changes are not so well accomplish...
