Death of dog. 















This animal was treated in a similar manner to Dog No. 5, but, 

 because the April night was not as cold as the night of March, 

 the dog was not sufficiently chilled to exhaust it of all its glycogen. 

 The first administration of adrenalin was therefore followed by a 

 rise in the D : N ratio, showing that a sweeping out of the carbo- 

 hydrates of the tissues took place. The second and third admin- 

 istration of adrenalin, however, failed to produce any extra sugar 

 elimination. 



These experiments show very clearly that adrenalin has not 

 the power of converting fat into dextrose.

A method for the determination of small quantities of iodine 

 in organic material. 



By ANDREW HUNTER. 



[From the Department of Physiology, Biochemistry and Pharma- 

 cology, Cornell University Medical College, Ithaca.~\ 



The estimation of iodine in thyroid gland and similar material 

 is usually carried out by the method of Baumann or one or other 

 of its various modifications. All varieties of the method have for 

 their basal operation the quantitative conversion of the organically 

 combined iodine into hydriodic acid. For the investigation reported 

 by Simpson and myself I have worked out a method which rests 

 upon a different principle altogether. 



By a procedure which involves, first, the oxidation of the 

 material with a mixture of saltpeter and potassium sodium car- 

 bonate, and, second, the action of an excess of chlorine upon the
