disorder will have taken place, which will also be indicated by the 

 pulse running violently upwards, from the tip of the finger, and in this 

 last case, it is probable, that vomiting and evacuation will ensue, if not 

 already prevalent ; phlegm is known when the pulse rises upwards fre- 

 quently, and fever when strongly ; when the pulse spreads, or becomes 

 broad on one side, from the tip of the finger, at the time of rising, this 

 will evince flatulence. If it get up, becoming thick in the lower semi- 

 knuckle, and thin in the upper, the symptoms of virility will be understood 

 to be deficient. Descending down the lower semi-knuckle, it will shew 

 a latent and n orbid state of the humours, and the approach of fever; 

 and even in a feverish state, the pulsation will be the same. 



If the pulse move upwards weakly or strongly, this will indicate 

 fever ; if such movement be not continual, it will imply a want of di- 

 gestion. If the motion, resembling that of a lapwing, and attended by 

 an almost imperceptible morbid state, becomes thick at once, the pulse 

 will languish instantly, and be a forerunner of death. If the pulsation 

 be at intervals, and confused, death is likely to happen, either after a 

 lapse of four or five days, or within a day or two. When the pulsation is 

 felt by the ring-finger, as drawing straight upwards, bodily, air will 

 appear to be prevalent; but when, being weak, it runs in the same 

 direction, and turns suddenly downward, flatulence will be apparent ; 

 besides, when the motion is slow or violent, and something like a knot 

 is felt, it may be taken as the sign of pain in the stomach. 



Should the pulse come down the semi-knuckle, phlegmatic fever will 

 become manifest ; and should this occur during a fever, attended with 

 ■violent motion, and descending directly, rheumatism will prevail. If 

 it move up in a triangular form, being broad in the lower and thin in 

 the upper semi-knuckle, phlegm wdl be discerned. If the pulse, felt 

 by the little finger, is straightly drawn up, the blood will be found in a 

 clarified state; but a knot being perceived in the middle, it will indi- 

 cate cold. 



When the pulse comes down, it will appear that the blood has un- 

 dergone some deterioration, and if not so already, that it will soon be 

 discharged naturally, or even flow through the ears or eyes.

I have now the pleasure to furnish an additional instance, in which I have ob- 

 served the surprising increase of some speciea of insects during the rainy season. 



About the 20th August, I accompanied some friends on an excursion to the 

 falls of Tarah, which are situated in the hills about 9 or 10 miles from Mir zap ur ;
