hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
The drawings referred to are those filed with the provisional specification numbered
and dated as above.
A. on the drawings is the glass tube or cylinder to receive lymph. B is an elastic
suction sack with neck (side view) fitted on to the glass cylinder: the operator will
now press with thumb and finger sack B. to exclude the air and place the glass
tube to the lymph on the patient's arm: loosen thumb and finger, and the lymph
enters the glass cylinder: stop with finger and thumb on the neck of elastic when
sufficient lymph is in glass cylinder: (seal glass tubes as usual for after use). To

Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1st. A saving of time in taking up the lymph, and the more even distribution of the
same in the glass tube, as no air spaces occur.

page_text: 2nd. Less pain to the patient in taking the vaccine.
3rd. The great feature of novelty is that the dirty and dangerous habit of placing
the vaccine tube between the lips, (sometimes cracked) when vaccinating, will be
abolished.
