duce to the variety and alteration of the sounds ; 

 either in respect of the greater quantity, or less 

 quantity of air, which the concaves receive, or in 

 respect of the carrying of sounds longer and shorter 

 way ; or in respect of many other circumstances ; 

 they have been touched, as falling into other titles. 

 But those figures which we are now to speak of, we 

 intend to be, as they concern the lines through 

 which the sound passeth ; as straight, crooked, 

 angular, circular, &c. 



221. The figure of a bell partaketh of the 

 pyramis, but yet coming off and dilating more sud 

 denly. The figure of a hunter s horn and cornet is 

 oblique ; yet they have likewise straight horns ; 

 which, if they be of the same bore with the oblique, 

 differ little in sound, save that the straight require 

 somewhat a stronger blast. The figures of recor 

 ders, and flutes, and pipes, are straight ; but the 

 recorder hath a less bore and a greater, above and 

 below. The trumpet hath the figure of the letter 

 S: which maketh that purling sound, &c. Generally 

 the straight line hath the cleanest and roundest 

 sound, and the crooked, the more hoarse and jarring. 

 222. Of a sinuous pipe that may have some four 

 flexions, trial would be made. Likewise of a pipe 

 made like across, open in the midst. And so like 

 wise of an angular pipe ; and see what will be the 

 effects of these several sounds. And so again of a 

 circular pipe ; as if you take a pipe perfect round, 

 and make a hole whereinto you shall blow, and, 

 another hole not far from that ; but with a traverse
