closed by the arm which carries it, but is wholly received and grasped by the 

 'other ; which likewise in its turn delivers it back again in the same manner. 



The motion of the whole machine is made at the rate as you move the handle 

 •of the serpent ; for then the arms cause the threads to open, and immediately 

 one of the arms begins to slide in towards the opposite arm, to which it carries 

 the shuttle, and retires immediately. At the same time one of the quarters of 

 a circle which held the clapper elevated quits it, and leaves it to flap, and then 

 the opposite quarter of a circle elevating itself, the other elbow changes the 

 threads, and the other arm retires, and so on successively. 



The advantages of this machine are these; 1. That one mill alone will set 10 

 or 12 of these looms at work. 2. The cloth may be made of what breadth you 

 please, or at least much broader than any which has been hitherto made. — 

 3. There will be fewer knots in the cloth, since the threads will not break so 

 fast as in other looms, because the shuttle that breaks the greater part can 

 never touch them. In short the work will be carried on quicker and at less ex- 

 pence, since instead of several workmen which are required in making of very 

 large cloths, one boy will serve to tie the threads of several looms as fast as 

 they break, and to order the quills in the shuttle. 



Of a Worm Voided by Urine. Communicated by Mr. Ent ; to whom it was sent 

 by Mr. Matthew Milford. N° 140, p. lOOQ. 



The worm when I voided it was then alive. It was snake-headed, of indiffer- 

 ent substance in the middle, and small at the tail. In length above half a yard. 

 I was very ill before it came away ; and ever since the urine seems mixed with 

 blood. 



• This relation is here set down in the patient's own words. It is most probable 

 he had had a suppression of urine for sometime, at the first making whereof the 

 worm was voided from one of the kidneys, wherein it was bred, into the blad- 

 der; and at the second from thence into the pot. — The worm when dead and 

 dry was of a dull red colour, and in thickness about the 12th of an inch. 



To make a probable Conjecture of Tempers and Dispositions by the Modulations of 

 the Voice in ordinary Discourse. Communicated also by Mr. Ent. N° 140, 

 p. 1010. 



Sitting in some company, and having been but a little before musical, I 

 chanced to take notice that in ordinary discourse words were spoken in perfect 

 notes; and that some of the company used eighths, some fifths, some thirds; 

 and that those were most pleasing, whose words, as to their tone, consisted
