88. And thus I had finidi'd the Chapter of bat that I | 
think fit to acquaint the Reader of a further defign I have concern- | 
ingthem, z/i^. Of enquiring hereafter into fome other accidents \ 
of Flants of an inferior quality to any before mentioned ; which 
yet perhaps are more abftrufe in their confideration than the more 
noted or eo are. And fuch are the blehs or blLlers we find on the 
leaves of many Trees and Shrubs^ which fomtimes happen to them 
after heat and droughts, and fomtimes too upon cold nipping 
weather: but whether thus infected from the from without, 
or by juices w^ithin, or by both ; and when by one, or the other, 
or both together ? is a Queftion requires a great deal of time, and 
more fedulity than has yet been afforded, to be but probably fol- 
ved. 
89. And this 1 the rather defign, becaufe all that I find certain 
concerning them yet, is only that the weak, and free growing 
fappy Trees are moft fubjeft to them,and the ftout Ever-greens but j 
little, if at all: thzt the infeSiion for the moft part is under, and 
the Z'//i7er above the leaf, but fomtimes otherwife : that the ^/i- 
y?m fomtimes Imve Infers in them, fomtimes hestr: fungu/s^s on 
their tops', and fomtimes have neither : But what kind of /w/et^?? 
or/«;7^Mi's they are, that belong to each Flant xh^t have them? 
or whether the fame Plants have not fomtimes different In[e6Is 
znd fungus' efpecially in dry, and wet years ? are alfo Queftions ■ 
that require indefatigable induftry, to be in any meafurefatisfied.'
