of time, as the water has to enter by the very holes through which it is 

 subsequently distributed. In my watering-despatcher (j%. 113.) I have 

 obvipted both the inconveniences; and on this account deem it decidedly 

 superior to the sonde, and the aquarian. 



« is a lifting clack, the same as used 

 in the bucket of the common pump, 

 which admits the water into the de- 

 spatcher, and will close securely as 

 soon as the despatcher is filled, b, an 

 upper valve, which is raised up by the 

 upward pressure of the air as the water 

 rushes in below at a ; and as soon as 

 the water has risen to the height of 

 the cover (c) the valve (b) falls, and 

 enables the user to take the despatcher 

 wherever he pleases. By raising the 

 valve (b) with the finger, the air is 

 admitted to act on the water, and any 

 quantity required may be discharged 

 through the small holes (d) at the 

 bottom. These holes are the same as 

 in the rose of the common watering- 

 pot. The clack will not allow a drop of water to escape from beneath it.

It will be here in place to remark that the Conductor, in his notice of 

 the sonde (Vol.V. p. 656.), proposed to improve shower-baths, by apply- 

 ing to them the pneumatical principle employed in the soude. This excellent 

 idea, expressed in 1829, it has subsequently appeared, had also previously 

 occurred to two others : first, to Mr. Murray, who (see Vol. VII. p. 2 1 9.) 

 as early as 1819 had applied this principle to the improvement of shower- 

 baths for adults, which shower-bath, thus improved by him, " he gave to 

 the public unfettered by a patent, and it has been found infinitely superior 

 to all the shower-baths [previously] in common use:" secondly, to a 

 Wrexham mechanic, who, previously to April, 1828, had invented, on the 

 very same principle, a nursery shower-bath (intended for children), as
