Weil's Disease. An infectious febrile disease, some- 

 what resembling typhoid fever, accompanied by mus- 

 cular pain and grave disturbance of the digestive 

 organs. See Diseases, Table of. 



Weisner's Tests. Tests for lignin. The specimen 

 is first acted on by hydrochloric acid, and then moist- 

 ened with a solution of phloroglucin in water and 

 alcohol. If the cell-walls are lignified, they will at 

 once assume a red color. Hohnel suggests the em- 

 ployment of a strong decoction of cherry-wood in- 

 stead of phloroglucin. Used in the same way, it im- 

 parts a violet color to lignified cells (Goodale). 



Weiss' Reflex. A peculiar curved reflex seen with the 

 ophthalmoscope parallel with and to the nasal side of 

 the papilla or disc of the fundus of the eye. It is 

 thought to be a sign of myopia.

Wenz's Method. A method of removing all the pi

 will be precipitated, and may be filtered off.

 Hemiopic pupillary inaction. It" a bright light i 

 thrown into the eye and the pupil reacts, the inl 

 of the reflex arc is demonstrated. It is possible 

 cases of lateral hemianopsia to throw the light J» 

 the eye so that it falls upon the blind half of the 1 

 If when this is done the pupil contraets, the indict'
