To change the syringe to a sprayer a cap (fig. 13, c) with a larger opening is put on 

 in place of the usual one, and into it is screwed the Vermorel nozzle. The nozzle 

 proper (fig. 13, n) necessarily has a very small orifice, and to fill the syringe through 

 this would require too much time; hence a larger opening is made (fig. 13, o), and 

 into this a ball valve is fitted (fig. 13, b). This latter is so arranged that when the 

 handle of the syringe is drawn up the liquid is drawn in through the opening, and 

 when forced down the ball valve closes the intake and the liquid issues from the 

 nozzle in the form of a mist-like spray.

This syringe, with its attachments, will be found valuable also for 

 whitewashing benches, shading glass, and other purposes. The syringe 

 under consideration was devised for the application of fungicides, but 

 it may be used for insecticides also and for the application of water 

 to plants; but for the syringing of plants with water, where this is

practiced on a large scale, still another apparatus has been devised in 

 the shape of a tip and nozzle of the form illustrated in figure 14. The 

 nozzle consists of a casting turned to the desired length and flattened 

 at the end, as shown. Through the flattened end a narrow slit is 

 made, and it is important that the slit or opening be absolutely true
