156 Sanitär y Studies of Baking Powders 



C. Repeat, in at least one series of tests, the essential features of 

 the experiments by Kahn (and Steel), on dogs, but use the alu- 

 minium analytic method newly adjudged to be the " best " (A). 



In Order to make this investigation comprehensive and particu- 

 larly reliable, and completely to forestall any possible suspicion of 

 prejudice on my part in favor of our previous findings, in case they 

 were correct and would be confirmed, I planned to put each section 

 of this research in charge of individuals or groups of workers 

 (" Units ") that would be geographically, psychologically and profes- 

 sionally independent. I proposed, to each individual or group of 

 workers involved, the Solution of specific problems withotit considta- 

 tion withj or giddance from, me, and without my divulging to any 

 " Unit " the name or names of , or the results obtained by, those in 

 the other " units," while the work was in progress. It was aimed, 

 in Short, to make the work of all the " units " coördinated but not 

 concerted. 



A copy of my requests of, and suggestions to, one of the groups 

 of workers involved, is published below. It ülustrates the method 

 of procedure referred to above, as applied to all the groups of 

 workers concerned. 



" My proposal is, in general, that you join a group of biological 

 chemists in an investigation of certain aspects of the 'baking powder 

 question' and that you coöperate in a study of the comparative 

 values of the best of the available methods for the biochemical deter- 

 mination of aluminium. This proposed study would involve the fol- 

 lowing conditions: 



" I. That it be conducted by you (and any assistants you would 

 have) with entire independence of the other workers on the sub- 

 ject, you to be kept in ignorance of their names and results, and 

 vice versa, until the Joint completion of the work. 



"2. Your report to me to be in the form of a finished paper for 

 the BiocHEM. Bull.; to be printed in that Journal after your ap- 

 proval of both galley and page proofs; and to be published nowhere 

 eise, prior to its appearance in the Biociiem. Bull. 



" It is intended to make this research f ar-reaching in scope, accu- 

 rate in conduct, useful in public Service, and creditable profession-
