ground, however uneven, it would search holes and hillocks 



equally. I turned my mind, therefore, to forma machine Machine aa. 



of this description, and thinking that the buoyancy of the ''**""8 **" 



wood would take oif from the weight of lead and iron about 



it, were 1 to extend it to ten feet in length, I determined on 



that length for it, and I found my expectation realised in 



the result. I therefore denominated it a machine or drag, 



easily drawn by one person, that fishes an extent of ten feet 



at one sweep, with the certainty of finding a body, if it lies 



within that space, let the ground be ever so uneven, or the 



water ever so deep. 



Permit me, Sir, to request you to submit this account of 

 my machine to the Society of Aits &c., accompanied with 

 models and a drawing ; and should they be honoured with 

 the approbatiou of the Society, I shall feel myself much 

 gratitied, as their sanction could not fail to promote their 

 publicity, 



1 have the honour to be, 

 Sir, 

 Vour most obedient servant,

Description of Mr. Milters Apparatus for Raising the 

 Bodies of Persons sunk under Water, PI. VI. Fig. 

 1, 2, 3, 4. 



This machine consists of a round piece of deal A A, fig. Apparatus for 



1. ten feet in length, and two inches and a half in diameter ; raising drown- 



. " If- • ^^ bodies ae- 



at thirteen inches from each end of it, a square piece of scribed. 



deal B, twelve inches in length, and one inch and a half in 



diameter, made firm by a bracket, is let in and glued or 



nailed. To this bar four six-poiuted drags, C C C C, are 



suspended at equal distances. These drags are weighted 



with two pounds of lead affixt'd or run on to the lowtr end 



of their shafts or stems, to steady ihem when in action, and 



to keep their points from running into the ground, which 



had they nothing to ronnteract their weight and preponder- 



ancy at top they would do. The buoyancy of the bar on 



the one hand, and the wei,ii,ht of the lead at the bottom of 



the drugs on the other, has the effect of keeping the drags
