Having the thumb and fore-finger about an inch and a quarter apart the operator now squeezes the gland tight enough to draw the skin firmly over it.
The reason the entire gland is not removed is that it is firmly united to the rectum and the animal is likely to be seriously injured if one attempts to remove the entire gland.
All of the scent, and only half of the gland is necessary.
When a gland is completely filled with a single large concretion, there are no free cells, as these have been all consumed in forming the concretion.
When a gland includes only a few very small concretions, or, as sometimes happens, none at all, it is easily overlooked.
How they escape from the gland is a marvel; but that they do escape is certain, for they are often found in the gizzard, intestines, and in the castings of worms, both with those kept in confinement and those in a state of nature.
