I have found that a hypodermic needle of small caliber is the best instrument with which to obtain blood from the ear or the finger, especially from children; it makes a clean, nearly painless cut and allows ample flow without the wound's closing, as so often happens when many other types of lancet are used.

It can be inserted through a cork and kept in a bottle stuffed with cotton and saturated with alcohol, so that it is always sterile when wanted. The patient sees only the cork, which causes no fear. This is advantageous especially with children. The illustration shows how the needle can be inserted through the cork for sufficient distance to allow penetration of the skin. This can easily be adjusted to suit the occasion.
