If an internal parenchymatous organ is desired, an incision 
is made throngh the skin, along the ventral aspect of the body 
from the pnbis to the sternnm, or the chin, and the skin is dis¬ 
sected back on each side. Then with sterilized knife and, if 
necessary, bone forceps or saw, the abdomen and perliaps the 
chest are laid open, so as to expose the organ or organs desired; 
great care must be taken to avoid wounding the stomach or 
bowels. Then, with sterilized hands the organ may be seized, 
cut ont and wrapped in a cloth wrung firmly out of a sublimate 
solution, as already advised. It may then be wrapped in paraf¬ 
fin paper, or in extra cloths wrung out of sublimate solution, 
and packed in a scalded jar, or in a box with cotton batting, 
salt, sawdust, wheat-bran, or charcoal for shipment. In all 
cases in which the organ is small (kidneys, lymph glands, pan¬ 
creas, etc.,) they should be sent uncut and unmntilated. In 
large animals in the case of the lungs, liver, spleen or other 
* 
large organs, a portion only will usually be sufficient, choice 
being made of a diseased portion. The excision of such part 
must be made with sterilized instruments, and the cut surface 
may be allowed to bleed, and may then be scraped with a ster¬ 
ilized knife before wrapping. 
7th. When it is desired to send liquids like pus, blood, or 
liquid exudation, wash and disinfect skin, hands and knives, as 
already prescribed, provide a bottle and cork that have been 
thoroughly sterilized by boiling, incise the sac or infiltrated or¬ 
gan and receive the liquid into the bottle direct. Cork and 
seal. A still more accurate method is to provide small glavSS 
tubes that have been sterilized by heat, and drawn to a point at 
each end and hermetically sealed, so that a vacuum is left 
internally, having disinfected the surface and incised the sac 
with a sterilized knife, one end of a vacuum tube is pushed into 
it, and its point is broken off by pressure against the inner 
surface of the wall of the sac, when it will instantly fill itself 
with the contained liquid. It is then withdrawn and hermeti¬ 
cally sealed in a gas or alcohol flame, or, if nothing better can be 
had, with melted wax.
