 bended and laid together in the manner delineated in Fig. 4, which nearly reprefents a

The length of the tube, and the places for the' holes, were made to correfpond with th? 

 proportions of an inftrument chatwas^ftraight, by meafuring a line that was teprefented as 

 drawn in the middle of the tube on a plan fimilar to that delineated in Fig. 2, but| of th^ 

 real fize. The li,ne topk a. femicirciilar turn at the end of every partition, and dcfcri{)ed
