very great, besides the certainty of getting himself laughed at by his indus- 

 trious plodding neighbours. No doubt the more general diffusion through- 

 out the country, by local colleges, or even periodical lectures, of those 

 branches of knowledge which are not to be acquired at the common country 

 or day schools, may do much good, by exciting all, and enabling many, to 

 apply barren knowledge to the affairs of life, with a readiness and precision 

 which only some fortunate individuals can at present attain. Your cor- 

 respondent partly illustrates this ; but if he had removed the beam from 

 his own eye, previously to his attempt to take the mote from the eyes of his 

 neighbours, and possessed a small knowledge of political economy, it would 

 have shown him the fallacy of the doctrines of Webb Hall, and have pre- 

 vented him from using arguments, the errors of which every tyro must 

 detect at first sight, and which, in fact, caused the withdrawal of the govern- 

 ment support, and the consequent breaking up of the Board of Agriculture. 

 It is really melancholy to see the errors into which the most humane and 

 kind-hearted men fall, from overlooking or contemning the science, which 

 is as necessary in enabling us to view correctly those plans for benefiting 

 society, as arithmetic is for estimating and noting the riches of individuals. 

 If a society is to be established, then, to prevent its failure, Professor Mac- 

 culloch, Professor Senior, or Dr. Whately, ought to furnish or revise the 

 rules, and, if possible, to give a preliminary lecture upon the legitimate 

 objects and advantages to be expected from such an association. I cannot 

 conclude without mentioning the liberality of the clergy of this diocese, who 

 have offered to endow two professorships at the new provincial college to 

 be established at Durham, by setting aside for their support the revenues 

 of two or three of the stalls of the prebendaries. I am, Sir, yours, &c. —

Heating a Conservatory and Bath from the same Boiler. — Your Maga- 

 zine has set me, and many others of my acquaintance here, experimenting 

 on some of the numerous inventions detailed in it. For example, I have 

 added to my cottage residence a conservatory, forsooth, on something like 

 the following plan : — 33 



a, Dwelling-house. 



b, Parlour. c, Conservatory. d, Bath. 

 /, Entrance porch, facing the south. 



e, Place for boiler. 



The conservatory has a glass front, and the front part of the roof is 

 glass, the back part being slated. Attached is a bath, sunk on a level with 

 the floor. Now, the cause of my troubling you is to endeavour to ascer- 

 tain from you, or some one of your scientific readers, the best plan of heat- 

 ing the conservatory and the bath from the same boiler ; the size of the 

 boiler, of the pipes, of the reservoir, &c. I suppose the thing can be done ; 

 if not, I shall lay all the fault at your door. — Cymro. Brecon, Dec. 1831.
