PYROTECHNY. 



Pyrotech- that are scattered throughout this article, and from the 

 y_-"]X_- general principles that have been laid down. 



As no useful arrangement could be made out of the 

 very limited materials of this branch of the subject, we 

 have made no attempt to adopt one, but have placed 

 the different receipts, with the remarks, in the same ir- 

 regular or accidental manner in which we have found 

 them in the different military treatises which we have 

 consulted. One article, namely, the method of making 

 matches, has been introduced here; although, with re- 

 spect to the cotton quick and slow match, these are 

 equally or oftener required in the ornamental branch. 

 The reader of the preceding part, will have no difficul- 

 ty in discovering how and when these things are to be 

 applied.

It may be used in iron or tin cases ; but it is not so ef- Fyrotech- 

 fectual as the former. Indeed it is more for show than n .v-
