Infeétis.| An abundance even of the {mall ticks gives 
the wool a yellowith, greenifh colour, the finenefs and 
foftnefs is increafed thereby. The Jarge tick I have 
only found in the Suflex and Herefordthire wool; in 
the latter, I have never found any harm therefrom; 
but in the Suffex wool and fheep it produces much
