DR. B. ANGUS SMITH ON THE 



ii6 children. Five of his analyses give numbers belom 

 20*6. These are bad cases. 



So far I had written on oxygen for the Mines Commis- 

 sion. Since that time many other specimens have been 

 collected by myself and assistants. 



Those from Scotland are suflSciently numerous to seek a 

 place for themselves^ and, at the risk of diminishing the 

 clearness of the arrangement, they may be here introduced. 

 I must also confess that I am unable to persuade myself to 

 write a new and independent paper on the subject, having 

 so lately completed the report ; the method of merely in- 

 serting the latest matter must therefore be adopted.
