Absorption of Apomorphin and Morphin. 27 



Apomorphin introduced into the nasal canal of the dog, proper 

 care being taken to prevent its reaching the pharynx, was also 

 found to be absorbed and to produce vomiting. 



In a similar manner the author has been able to show the 

 absorption of apomorphin and morphin through the urethra, 

 the prepuce and other structures. A comparative study of the 

 absorptive powers of the urethra (in the male) and the bladder, 

 is now in progress. 



After having studied the absorption of apomorphin and mor- 

 phin through the above-mentioned channels, the author has 

 undertaken an extensive investigation concerning the absorption 

 of a large variety of drugs and poisons through the same channels, 

 the results of which investigation will appear in due time.
