| Abstract: | A guide or template is described which facilitates placing the cylinders on the agar surface in the plate assay of penicillin. The general plan of conducting the assay is discussed and several advantages of the use of the guide are noted. We wish to thank Mr. Albert G. Sterling, instrument maker, for fabricating the guide and the aluminum cylinders. |
