the opinion that there must have been technical mistakes in the 

 experiments of Vansteenberghe and Grisez ; some time afterwards 

 he was enabled to convince himself of the incorrectness of their 

 opinion by his own experiments 1 ). 



Mironesco 2 ) after bringing fine particles into the stomach of rabbits, 

 was not able to recover them in the lungs. 



In August 1906 Vansteenberghe and Sonneville 3 ) described a 

 new series of experiments which confirmed the results of Vansteen- 

 berghe and Grisez. 



Fine particles which were brought into the mouth with a catheter 

 were already to be recognised in the lungs after a lapse of 5 or 6 

 hours. 



Soon afterwards the opinion of Vansteenberghe and Grisez was 

 opposed by two authors: Schulze 4 ) in a temporary publication con- 

 cluded that the pulmonary anthracosis could not proceed from the 

 resorbing of fine particles from the intestines and Prof. Spronck com- 

 municated shortly afterwards at the 5 th International Conference on 

 Tuberculosis the results of some of the following experiments, which 

 were adverse to the results, gained by Vansteenberghe and Grisez. 



In a more extensive treatise .Schulzk 5 ) demonstrated further how 

 substances are lightly aspirated into the lungs either by administering 

 them with the catheter or by ordinary eating. A rabbit however, 

 had received within two months the total quantity of 200 grams of 

 vermillion through a gastrotomy, yet no trace of vermillion was to 

 be found in the lungs. 



On the other hand some investigators took the part of Vansteen- 

 berghe and Grisez: Petit 6 ) brought carbon particles into the stomach 

 of six children who were in an advanced state of tuberculosis or 

 athrepsy and after a post-mortem examination he found pigment in 

 the lungs in three of them and Hermann 7 ), on the authority of 

 experiments, esteemed an intestinal origin of the lung-anthracosis 

 possible, but compared with the inhalation-anthracosis of very inferior 

 significance. 



Afterwards the results of Vansteenberghe and Grisez were empha-
