The Book of ceremonial Magic

The experiment in the Grimorium Verum is worded as follows:--
THE INVOCATION OF URIEL
To succeed in this operation, it is needful that whosoever makes the experiment shall do
in all things as hereinafter enjoined. Let him choose a small chamber or cabinet which
has not been frequented by impure women for at least nine days. Let such Place be well
cleansed and consecrated by aspersions and fumigations. In the middle of the said
chamber let there be a table covered with a white cloth; set as follows thereon--to wit, a
new glass phial filled with spring water, drawn shortly before the operation; three small
tapers of virgin wax mixed with human fat; a sheet of virgin parchment six inches square;
a raven's quill cut ready for writing; a china ink-well filled with fresh ink; a small pan
furnished with the materials for a fire. Let there be also a young boy of nine or ten years,
cleanly and modestly dressed and of good behaviour, who must be placed near the table.
One of the three tapers should be fixed upon a great new needle at a distance of six
inches behind the phial,

and the two others, erected after the same manner, should stand on the right and left at
the same distance. While arranging these matters, recite the following words:--
Gabamiah, Adonay, Agla, O Lord God of Powers, do Thou assist us!
The virgin parchment should be on the right and the pen with the ink on the left side of
the phial. The windows and door must be closed before beginning the operation. The fire
should then be stirred, the tapers lighted, and the boy placed on his knees so that he can
look into the phial; observe that he should be bareheaded and his hands joined. The
Master of the operation shall thereupon command him to gaze fixedly into the phial,
when, approaching his right ear, and in a moderate tone of voice, but as distinctly as
possible, let him make the following
CONJURATION
Uriel, Seraph, Josata, Ablati, Agla, Caila, I pray and conjure thee by the Four Words
which God uttered with His mouth unto His servant Moses, Josata, Ablati, Agla, Caila,
and by the Nine Heavens wherein thou dwellest, as also by the virginity of this child who
is before thee, that thou appearest, and without any delay, visibly in this phial, to
discover, without disguising, the truth which I desire to know; which done, I will
discharge thee in peace and goodwill, in the Name of the Most Holy Adonay.
After this conjuration the child must be asked whether he beholds anything in the phial;
and if he should reply that he beholds an Angel or another apparition, the Master of the
operation shall say in an affable tone of voice: Blessed Spirit, be thou welcome! I conjure
thee once more, in the Name of the Most Holy Adonay, to give me prompt enlightenment
