cess, enabling them to exert more strength in moving their limbs, he will not 

 pretend to say. 



Perhaps some permanent advantage might have been obtained, if the electric 

 shocks had been accompanied with proper medicine and regimen, under the di- 

 rection of a skilful physician. It may be too, that a few great strokes as given 

 in his method, may not be so proper as many small ones ; since, by the account 

 from Scotland of a case, in which 200 shocks from a phial were given daily, it 

 seems that a perfect cure has been made. As to any uncommon strength sup- 

 jxjsed to be in the machine used in that case, he imagines it could have no share 

 in the effect produced ; since the strength of the shock from charged glass, is in 

 proportion to the quantity of surface of the glass coated ; so that his shocks 

 from those large jars must have been much greater than any that could be re- 

 ceived from a phial held in the hand. 



Zijr. Observations on the late Comet in Sept. and Oct. 1757 ; made at the Hague by 

 Mr.D. Klinkenberg. Translated from the Low Dutch, p. 483. 

 Mr. K. observed this comet from Sept. l6th in the morning, till Oct. the 

 11th in the morning; and found its situations, according to his method, as 



follows:

But the last 2 observations will, in his opinion, differ the most ; because when 

 made he was in some doubt about the adjustment of his instruments ; and the 

 comet was then far advanced into the morning rays. 



As his above-mentioned observations on the comet appeared too incorrect to 

 undertake a calculation for ascertaining its path by the theory, he contented 

 himself with effecting it by a construction. By this means he found on a figure, 

 whose globular or spherical diameter was 13i Rhineland inches, as follows: 



That the comet was in its perihelion the 21st of October, at 2 in the afternoon : 

 the place of the perihelion 3° in Leo. The comefs distance in the perihelion 

 from the sun was about 34 parts, of which 100 make the mean distance between 

 the sun and the earth. The inclination of the comet's orbit with the ecliptic
