Mr. herschel’s Account 
Mifcellaneous obfcrvations and remarks, 
March 19. The Comet’s apparent motion is at prefent 
feconds per hour. It moves according to the order of the ligns, 
and its orbit declines but very little from the ecliptic. 
March 25. The apparent motion of the Comet is accele- 
rating, and its apparent diameter feems to be increafmg. 
March 28. The diameter is certainly increafed, from which, 
we may conclude that the Comet approaches to us. 
April 2. This evening at 8 h. 15' the Comet was a little 
above the line drawn from to 6 in fig. 7. This figure is only 
delineated by the eve, fo that no very great exaftnefs in the 
diflances of the liars is to be expedted ; but 1 fhall take the 
firft opportunity of meafuring their refpedlive fituations by the 
micrometer. 
April 6. With a magnifying power of 278 times the Comet 
appeared perfectly lharp upon the edges, and extremely well 
defined, without the leaf! appearance of any beard or tail. 
April 16. Fig. 8. reprefents the lituation of the Comet this 
evening about nine o’clock, and is only an eye-draught of the 
telefcopic liars. 
Remarks on the path of the Comet . 
We may obferve, that the method of tracing out the path 
of a celellial body by taking its diflance from certain flars, and 
the angle of polltion with regard to them, cannot be expedled to 
give us a compleatly juft reprefentation of the tradl itdefcribes, 
fince even the moll careful obfervations are liable to little errors, 
both from the remaining imperfections of inllruments, though
