48 C. II. Palmer — Eemarlcable Case of Hydration. 



As to any formula being deduced from the analyses given, 

 the case seems hopeless without resorting to assumptions that 

 are, to say the least, questionable. 



The duties of a commercial laboratory afford scant opportu- 

 nity for purely scientific investigation, however interesting, and 

 it was only after many interruptions that the above work 

 was accomplished, but it is offered as food for speculation and 

 a stimulus for future investigation with the hope that some one 

 with more time and ability may be able to grasp the significance 

 of this remarkable behavior.
