KNOWLEDGE 



the whole system of scales, modes, changes of key, &c., are un- 

 doubtedly built up. Into this part of the subject we now pass. 



It is a matter of experience that all the notes of each chord may 

 be sounded together, and in each instance the effect produced is 

 harmony, but harmony however of a diilereiit quality, easily dis- 

 tinguishable, and known as major or minor. But the effect of 

 destroyed if both chords are sounded together. ""

 the scale differ by the ratio 80 : 8i. 



This second pair of chords conjoined to the former pair complete 

 then the construction of the diatonic scale, which in the key of C 

 consists of these notes, as placed in one octave, C, d', d", e, f, g, a, 

 b, c, the respective ratios of which are 1, '3°, f, J, J, f, y, J. 



But the diatonic scale is not the only scale ; or, to speak more 

 definitely of its n.aturo, it is only a part of a continuous system of 

 notes. It is, however, the most important part; in fact, the one 

 necessary parent stem, of which all other scales, keys, and notes

In conclusion, I would remark that whilst the scale is thus shown 

 to exemplify the law of evolution, it equally appears to exemplify 

 design in nature, teaching, in fact, that evolution is the one simple 

 mode according to which the purposes of nature are fulfilled.

LETTERS RECEIVED AND SHORT ANSWERS. 

 Jas. Brown.— The explanation of saltness of sea in " Chambers's 

 Encyclopaedia" is unsound. The salts which form ingredients of 

 the crust have been derived from the sea. Doubtless the saltness 

 of the sea is due to the presence in the earth's primaeval atmo- 

 sphere of those elements now found in the sea.— R. G. L. Quite 

 agree with you. — F. W. H. The subject is disposed of. It nothing 

 is anything to man until he becomes conscious of it, I opine that to 

 999 out of 1,000 readers of Knowledge, Hylo-Idealism is naught.— 

 Atlas.— Dr. Wigan's book is long since out of print. I believe it 

 was originally published by Longmans.— Coxst.4Xt Subsceiber. Do 

 not know the address. An editor has usually a good deal to do 

 besides looking after such matters.— S. G. Only the feeling that 

 it is best to say no more on a subject which should not have been 

 touched on, prevents me from publishing your juat and well- 

 worded remarks. Ten lines of her writing outvalue all that 

 those Pharisees (who can only judge, however, from their inner 

 selves) have done of good in all their lifetimes. — Hiltox 

 FCLCKE. The book is anonymous. Try the publishers, Bailliere, 

 Tyndal & Cox.— R. M. D. As a very busy man I cannot undertake 

 to make the necessary inquiries. Note advertisements in our 

 columns.— Zeteo. Of course. Or, Assume a finite line,— it can be 

 produced, and produced again — for ever. — Boyd Moss. Have not 

 read that book. There is so much to be done in this world, that 

 those outside inquiries do not invite me. On the other point, it is 

 the " popular conception" which overlooks that — not I. Jfi/ ideas 

 on the subject have no contact, even, with the popular conception. 

 1:1.1 what can it matter to the world what I think ? That is the 

 LT. a; nuisance of such subjects ; they set a lot of unwise folk eagerly 

 lulling the worldwhat they think— as if it mattered.— J. R.Corder. 

 I am not the publisher of that work or of any other; do not know 

 its price, or exact name.— Com.mentator. Readers object, and 

 naturally, to disquisitions so exuberant and dealing 30 wildly with 

 so many subjects. A change is preparing which will leave very 

 little room for correspondence, and none for replies in the Know- 

 ledge of the future. We begin l.y cliaiinating letters running to 

 extravagant length, and v.. .iiire. Your sugges-
