with a similar result. Thus no trace of iodine was to be found in 

 12 eggs or in 600 or 6700 grms. of milk. The fluids in which the 

 iodine must be concentrated amounted in all cases only to a few 

 centimetres ; for testing them, cold starch-paste and pure nitric acid 

 into which nitrous acid had previously been passed were employed. 

 The author does not deny, that, by the employment of still larger 

 quantities of milk and eggs, the exhibition of iodine may perhaps be 

 possible, and that under certain circumstances iodine may also occur 

 in the atmosphere, especially in the neighbourhood of manufactories 

 and chemical laboratories ; but from his experiments he considers 

 that he may draw the conclusion, that Chatin's statements are to 

 be considered as erroneous throughout, and that the absence of 

 iodine in the air cannot be the cause of goitre and cretinism. —
