case, with two needles.

Pasteur Institute, Paris, 2c.c.,price $4 OO

We appreciate the importance of a good toxin syringe in 
laboratories, and have experimented considerably in the matter, 
with the result that we believe the above is the very best that 
can be made for the purpose. It always gives satisfaction when 
not carelessly handled.
