ridiculed by others; it is to be hoped, therefore, the 
knights of the kennel, who are materially interefted 
in the queftion, will endeavour to clear up this and 
other difputed points by decifive experiments. 
On examining this white worm-like fubftance, which 
is about two inches long, originating under the point 
of the tongue, and extending longitudinally between 
the hyoeidei and ftylo-hyoeidei mufcles, it is, I find, a

remains wholly unknown. Having lately difcovered 
it to be tubular, may it not be an excretory duét, or 
neceflary appendage to the adjacent falivary glands? 
May not its removal influence the fecretion of mucus 
or faliva, or in fome meafure diveft it of the power 
of contracting a contagious quality ?
