space of two minutes. 
A few days afterwards, two of the Portuguese clergymen of 
this city having been furnished with proper instruments, made 
an excursion to the hot-wells, a written account of which I was 
favoured with on the 20th April 1819. I also received other 
specimens of the water, carefully taken, on which the tempera- 
ture of the wells which my friends examined, were marked with 
great care. 
Although the result of the analyses of the water only proved 
that it was sea^ water mixed with about an equal part of com- 
mon water, yet a temperature extending from 130° to 190° Fah- 
renheit in the hottest spring, presented facilities for warm-bath- 
ing, which, together with the advantages of change of air, scene, 
and the journey, promised great benefit to the sick and conva- 
lescent. These circumstance induced Sir Theophilus Metcalfe, 
then the chief of the British Factory, and himself a conva- 
lescent from a protracted illness, to apply to the Chinese local 
magistrate for permission to have free access, both by land and 
water, for the benefit of himself and others. After some hesi- 
tation, this request was civilly refused, under pretext that the 
concurrence of the military commandant was necessary, and 
which his instructions would oblige him to refuse. 
Having thus no prospect of visiting the hot- wells in a regular 
and comfortable way, I begged to accompany the gentlemen 
who gave me the account of them, when they went again to the 
springs. Circumstances which it would be foreign to this ac- 
count to detail, prevented them from being able to gratify my 
wishes till yesterday, when I had the pleasure to examine these 
very interesting hot-springs, together with my friend Mr Beeves, 
We left Macao before four o’clock in the morning of the 
11th April 1821 for Yom-Mack, the name of the place where 
the hot-springs are situated, in East Long. 113° 28'; and North 
Lat. 22° 24'. This agrees with the Portuguese estimated dis- 
tance in a direct line ; but as our fast-rowing boat was five hours 
and a half, with a favourable tide, in reaching the spot, the dis- 
tance must rather exceed than fail short of twenty miles. 
I was happy to observe, that the account of my Portuguese 
friends, so far as it goes, is sufficiently exact. It will therefore
