We make it a rule always to correct errors of the press or of other kinds, as soon as noted; other papers rarely do so, and hence, may seem to have claims to perfection which the Gardeners' Monthly might not aspire to. The fact is we seldom take up a scientific paper without noting these uncorrected errors. Just before us as we write, we find Mr. Bennett, the well known botanist, writing of a Cactus, is made to say he collected "Maxillana" vivipara in the Rocky Mountains, which is an orchid. He of course wrote it Mamillaria.

Another who wants to tells us how to propagate the common Evergreen burning bush - Euonymus japonica - and its numerous varieties, is made to speak of "Eulalia," a well known grass, in every instance that the name occurs through the whole chapter. It reads very funny, that we should *' take cuttings of the wood three inches long of the Eulalia japonica variegata" in the case of a common grass. We are no better than our neighbors in these misfortunes, but we would not be considered worse because we correct these mistakes, and thus let people know they are made who would never see them for themselves.
