Dear Alfred,

I have looked over Schimper's¹ Synopsis of European Mosses² the best work on the subject and I find in 2^nd Ed[itio]^n. 1876 there are enumerated about 880-890 accepted species[.] I do not fix on an exact number for some species are disputed or denied and others are accepted by the author as usually happens in books of this kind — of the above 586 are enumerated in the Catalogue compiled by Hobkirk³ and Boswell⁴ for the Botanical locality club and called the London Catalogue⁷[.] [T]his was published in 1878. As there are a few more not mentioned in this it may be said that we have 570 species in the British islands [and] of this number 18 only are confined [2] to England[,] Scotland and Ireland[.] [O]f this 18, nine are confined to Britain i.e. England and Scotland, the others are Irish which are quite or almost quite confined to that island. The British species are mainly species of genera widely spread in England, with one exception, and they offer nothing remarkable being nearly allied to other wide spread species, on the other hand the Irish are very remarkable. Hookeria laetevirens, Daltonia splachnoides. Tortula hibernica and the two lush forms, only these, the Hookeria exists in a maritime [word illeg.] in Cornwall[.] [T]hese two — the Hookeria the Daltonia and the one English species excepted above (Streptopagens gemmaseens[?]) are all three species of genera whose centres of greatest development is in the Equatorial Andes, they are [3]⁷not represented elsewhere in Europe[,] N[orth] America nor any part of the N[orthern]. Hemisphere; India and the Malay Archip[elag]^o. and Pacific. Il[and]s are almost destitute of species, not more than one species is known from Africa. In making comparison of British species with European, it must not be left out of consideration, the many promising quite unexplored regions — Spain, Italy, Sicily, Turkey, Greece, and much of Eastern Europe; the best explored are in the following order G[rea]t. Britain, Scandinavia, Germany, Belgium, France.

About 143-150 Hepaticae are found in G[rea]t Britain ten[?] are confined to Scotland and about 3 are exclusively Irish and 7 others not found elsewhere in Europe, one of these is however found in the Himalaya[.] I am not however able to get at the exact number of European species from knowing[?] [word illeg.] Synopsis [word illeg.] in the case of the mosses.

Let me know what further you want in this matter and I will hunt it up.

We are all pretty well, have had much snow, all covered now, frost severe. Could hardly keep it out of my greenhouse. Ma has been well so far. I hope you have shaken off your cold.

With love to Annie[,] Violet and Willie.
