w 



fluid, and substituted B fluid without arsenic, I believe the body 

 would have been permanently preserved. It was neglected, how- 

 ever, in this respectj although I watched it with some solicitude 

 until, after the lapse of rather more than twelve months, I found 

 the entire body (with the exception of the bones) reduced to the 

 condition and appearance of decomposing size, except that it 

 remained perfectly sweet. I have made a number of experi- 

 ments, with the like results. I have seen the characters of mus- 

 cle, tendon, nerve, (fcc, gradually disappearing, until nothing but 

 a glairy fluid remained, but which was always perfectly siveet 



The softening ptoperty is that for which I employ arsenic ; 

 either to recover animals that have been hardened, and corruga- 

 ted in alcohol, or to enable me to proceed with elaborate dissec- 

 tions of nerves, which must necessarily be tedious. My friend 

 Dr. T. S. Beck of London could never have made such a display 

 of the nerves of the uterus — the finest dissection of nerves m 

 the human subject that I believe has ever been made-— with- 

 out the aid of arsenic, which was never allowed to do mischief, 

 occasionally washed away, then renewed, and so on; and the 

 nerves, under its well regulated influence were as tough as cop- 

 per wire, and although very delicate in appearance, would bear 

 pulling and stretching with impunity. 



The aluminous fluids I originally designated by the letter A, 

 and I called them 1 or 2 as the same weight of the ingredients^ 

 were dissolved, either in one quart of water or two quarts; they* 

 are thus made. 



Rock salt, 

 Alum, • 



A, 2 



4 ounces, 

 2 ounces. 



Corrosive sublimate, .... 4 grains. 

 Boiling water, . , , ,2 quarts,* 



The Al only differs from the above in having half the quan- 

 tity of corrosive sublimate, and water. It is very rarely used, 

 being generally too astringent. 



8 ounces. 



Rock salt, ..... 



Corrosive sublimate, . • . 2 grains. 

 Boiling water, 1 quart.

.The corrosive sublimate must never exceed, under any circum- 

 stances two grains per quart of water; otherwise there will be in 

 timS a while precipitate on the preparation that cannot be re- 

 moved, and which will greatly disfigure it. 



The imperial quart of 40 ounces' is intended to be understood tlirougliout this

paper.
