 regularity and frequency. 



The following list exhibits the numbers of killed and injured 

 during the last 16 years.

From this Table it will be seen that 590 explosions have 

 occurred since the foundation of the Association, killing 987 

 persons, and injuring 1187 others, while to this it may be 

 added, that many thousand pounds' worth of property has 

 been destroyed. This return, however, does not include the 

 total number of explosions, or the total number of persons 

 killed and injured during the period referred to, since in the 

 early years of the Association's operations such complete 

 records were not kept as is now the case, so that many 

 escaped its notice. At the present time there occur on an 

 average 50 explosions a year, killing about 75 persons and 

 injuring as many others, so that an explosion occurs every 

 week, and one person is killed every fourth working day in 

 the year. 



Proposition No. 2. 



That boiler explosions are not a necessary consequence 

 of the use of steam, but that they are preventable. That 

 though complicated in result, they are simple in cause ; 

 arising in the main from bad boilers, bad either in con- 

 struction, or bad in condition. That six explosions are due
