This with rooft of the Letters between Mr. Crabtrie 
ani Mr. Gafcoigne , together with other very valuable 
Papers of Mr. Horrox , Mr. Towneley himfelf, Mr. Collins , 
Mr. Shufe , and other great Men, were imparted unto me, 
the laft Month, by the great favour of Charles Towneley 
Efq.5 Sen of the late moft Ingenious Rich . Townley Efq* 
of Lancajhire. 
And torafmuch as every thing of Mr. Crabtrie' s is 
valuable, I have taken this occafion from my ownObfer- 
vations of the Solar Spots (for the moll part drawn up 
near 4 Years ago) to give Mr. Crabtrie’’ s Letter at large, 
containing as well fome things of another Nature, as 
- what relates to the Spots 5 not doubting but the one will 
be acceptable to the Curious, as well as the other. I have 
two other of his Letters concerning the Spots (with 
Mr. Gafcoigne s Anfwers.) One contains his Theory of 
their Motion and Appearances $ the other, his way of 
obferving them. But being long, I have not time at 
prefent to fit them up for the Societies Ufe $ but intend 
(God willing) to do it as foon as may be, if this Spe- 
cimen be acceptable.
