XXXII. Account of fome Obfervations tending to invefligate the 
Confiruction of the Heavens. By William Herfchel, H/q.

Na former paper I mentioned, that a more powerful in- 
(trument was preparing for continuing my reviews of the 
heavens. The telefcope I have lately completed, though far 
inferior in fize to the one I had undertaken to conftruét when 
that paper was written, is of the Newtonian form, the object 
{peculum being of 20 feet. focal length, and its aperture 18.7, 
inches. The apparatus on which it is mounted is contrived fo 
as at prefent to confine the inftrument to a meridional fi ituation, 
and by its motions to give the right-afcenfion and declination 
of a celeftial objet in a coarfe way ; which, however, is fuf- 
ficiently accurate to point out the place of the object, fo that it 
may be found again. It will not be neceffary to enter into a 
more particular def{cription of the apparatus, fince the account 
I have now the honour of communicating to the Royal Society 
regards rather the performance of the telefcope than its con- 
ftruction. 
It would, perhaps, have been more eligible to have waited 
longer, in order to complete the difcoveries that feem to lie 
within the reach of this inftrument, and are already, in fome 
refpects, pointed out to me by it. By taking more time I 
ould undoubtedly be enabled to fpeak more confidently of the
