| Description | Thanks for copy of note Spray proposes to send to <i>Nature</i> - does not think this adds anything to Brian's note - would not reflect to Spray's credit as analyses Spray quotes for frequentic acid does not suggest formula C5H5O3 - discusses this and implication that this formula was calculated by authors of the antibiotics monograph - astonished that Spray can so lightly admit that his original report on frequentic acid was known to be incomplete. |
