the lingual terminations of the glosso-phaiyngeal nerve, or on the 

 lingual branch of the fifth nerve and produce salivation. Sialogogues 

 are either (1) topical or direct, or (2) specific, remote or indirect, to 

 follow Dr. Lauder Brunton's classification of them. Ginger, the 

 most typical species of the order to which Bhui-Champii belongs, 

 is classed by him as a topical sialogogue. It is a very pungent 

 substance. Bhui-Champa is by no means so pungent, yet it has an 

 unmistakably '* bitter, pungent, camphoraceous taste." And here 

 I am using the words of our careful and experienced clinical 

 observer. Dr. Dymock.* Now the lesser amount of pungency is a 

 mere question of degree ; mere pungency, however, may not have 

 much or anything to do with salivation ; for in addition to the pun- 

 gent element which ginger contains there are other crystallizablc and 

 non-crystallizable principles in it. For a fuller knowledge of these, 

 the reader may be referred to the valuable researches of Dr. Thresh 

 in the Year-Books of Pharmacy for 1879 and 1882 respectively. 

 It may be presumed that Bhui-Champa possesses some of these 

 principles. It is for the future pharmacologist and chemical analyst 

 to determine what they may be. I am now noting only what has 

 been my clinical experience, and not what I can analytically or 

 experimentally account for. 



Now to come to another point. Clinically speaking, intense 

 salivation has been known to be a forerunner of vomiting, or is an 

 accompanying or accessory phenomenon. Dr. Lauder Brunton notes 

 that "the nerves which convey stimuli from the stomach and excite 

 salivation which accompanies nausea are contained in the vagus." 

 I have also the testimony of such a careful observer as Brigade- 

 Surgeon Lieutenant-Colonel Wellington Gray, Principal of Grant 

 Medical College, who, when he was Acting Chemical Analyser to 

 Government and Professor of Medical Jurisprudence, thus observed 

 in his ofiicial report for 1 874,75 : — 



" The occurrence of salivation mentioned by Colonel (now General 

 Sir Robert) Phayre as having come on when he began to feel the 



* Since these lines were written, Dr. Dymock has departed this life, to the great 

 sorrow of the scientific world. Indian Botany has lost an earnest, indefatigable, quiofc 

 and unostentatious worker at a time when hiti mature kuowledge was being used by 

 him for the advancement of botanical and therapeutical sciences with the stamp of 

 unquestionable authority. — K, B. K.
