Injections of Sulphurous Acid. 39 



Injections of Sulphurous Acid. 



The acid used was a saturated solution of S0 2 , 

 made expressly for me by the late Professor J. B. 

 Kirkland. 



October 11, 1869. Injected into the left external 

 jugular vein twenty-five minims. 



Result. Breathing slightly hurried. 



A quarter of an hour after, another twenty-five 

 minims were injected. 



Result. Nothing but slightly accelerated breath- 

 ing. 



Between three and four hours afterwards, I injected 

 into the same do^, using both external jugulars, more 

 than half an ounce of the same sulphurous acid. 



Result. None other than recorded above, the dog 

 remaining quite well and lively. 



COMMENT. 



I was naturally surprised at these results, and 

 doubted the strength of my solution. 1 therefore 

 took half a teaspoonful, and placed it in my mouth. I 

 became nearly suffocated, the fumes arising closing my 

 glottis, and going wherever it suited them. This is 

 an instance of the value of practical work, for I shall 

 never do such a foolish thing again. 



In September 1875, I re-commenced these experi- 

 ments under the control of our Professor of Chemistry, 

 the late J. D. Kirkland (a tablet regretting his death, 

 and showing his worth, may still be seen in the 



vestibule of our Medical School).
