HEPATIC^. 593 
burgh Bot. Society, vol. 3, 1849. In this excellent treatise, 
no less than 387 mosses are enumerated, and the whole put 
in a natural arrangement into 35 tribes. His Pyrenean 
collection of Hepaticae amounted to 92. These are arranged 
for the first time in any British publication, under the more 
modern generic names adopted in the " Synopsis Hepaticarum 
by Dr. Gottsche, Lindenberg, and Nees, 1844." 
The account of this tour in the Pyrenees contains some 
critical observations on the distribution of Pyrenean Musci 
and Hepaticae according to the zones of elevation in which 
he collected his plants ; these are very good, and well deserve 
the careful consideration of all students. After his return 
from the Pyrenees in April, 1846, he settled himself at Wel- 
burn near Castle Howard, when he carefully examined and 
arranged his fine gathering of plants, comprising both 
Phanerogams and Cryptogams, and issued mounted named 
sets of specimens, amongst which some new species are 
described, and careful observations made on others not well 
known. Spruce remained at Welburn until 1849, when he 
started on his great exploring expedition to the tropical 
region of South America. He landed at Para at the mouth 
of the great river Amazon in July, 1849, and did not return 
to England until 1864. 
For a short notice of his travels, see " Voyage de Richard 
Spruce dans lAineriqtie equator iale pendant les annees 
i84g-i864.'' This is written by the author himself, in the 
French language, and published in the Revue Bryologique, 
1886, No. 4, pages 61 to 79. Spruce returned to England a 
confirmed invalid, suffering from an attack of paralysis which 
had seized him when exploring the Peruvian Andes in i860, 
from which he never recovered his bodily strength, and 
during the remaining years of his life he was never able to 
take active outdoor exercise. 
He returned to Yorkshire in 1866, coming to the village of
