and the fineness of its branches giving it a most graceful appearance, and gaining 
for it in Paris the name of Marabout. This plant, more generally called 
Tamarix japonica, probably originated from a bud of T. indicci, which assumed this peculiar 
manner of growth. It is as hardy as T. indica, and its culture and multiplication are identical. 
-instance of Variegation induced by Grafting occurs in the nursery of 
Mr. W. Paul, at Waltham Cross. The tree is the Chestnut, Castanea vesca. 
The variegated variety of the Chestnut had been grafted, standard high, on an 
ordinary green-leaved Chestnut stock; the graft took, but from some cause or other afterwards 
died off, and subsequently a young shoot, with well-marked variegation on its leaves, broke 
out from near the base of the stem. The variegation is of a creamy white colour, and marginal. 
- its a Covering for Lawns , in the case of hot sandy slopes where lawn 
grasses cannot maintain their ground, the adoption of common Wild Thyme, 
common Yarrow, and common Chamomile as substitutes for the grasses has 
been recommended. Some banks which have been so treated have yielded, it 
it said, a peculiarly dense and beautiful turf. 
- new patent gas stove, called the Calorigen , seems likely to be a useful 
apparatus for heating small conservatories, as the temperature can be regulated 
to a nicety without risk of over-heating. The annexed illustration shows the 
general 
outline of the stove. In rooms or buildings 
where a chimney is not available, two holes are made in 
the wall to allow the pipes F and F to pass through. The 
cylinder E is attached to the ends of the pipes F and F, 
with the open end upwards. When the gas is lighted the 
products of combustion leave the stove by the upper pipe 
f, being discharged into the cylinder E ; at the same time 
a current of air passes down the cylinder E through the 
lower pipe f, to support combustion. One end of the pipe 
G is inserted in the opening at the bottom of the stove, 
while the other end is carried either through the floor or 
wall, to communicate with the external atmosphere. 
When the gas is burning in the stove it will heat the coil 
contained therein, thereby causing the air to rush in 
through the pipe G, and out of the opening h, and by 
these means affording a constant supply of pure warm air. The door of the stove is kept 
closed, and when not in use a cap is placed on the outlet n. Water being one of the results of 
combustion, the pipes F and F decline slightly from the stove, and so cause it to flow into the 
cylinder, where a small hole is provided for its escape. The manufacturers are Messrs. J. F. 
Farwig and Co., 36 Queen Street, Cheapside, E.C.

-I3r. Berthold Seemann, F.L.S., the well-known botanist and traveller, 
died at the Javali Mine, Nicaragua, on October 10, from fever caught at Colon. 
He was born at Hanover in 1825, and became a pupil in Kew Gardens. In 1846

he was appointed naturalist to H.M.S. Herald, then on a surveying expedition in the Pacific, 
and in 1859 was sent as a Government Commissioner to examine and report on the Fiji 
Islands. The result of this journey was the publication of the Flora Vitiensis, as that of his former 
voyage was the publication of the Botany of H.M.S. Herald. Dr. Seemann established the 
Bomplandin , a botanical journal, and the Journal of Botany , British and Foreign; and was the 
author of the only Popular History of Palms we have. Many new plants were introduced 
and many papers contributed to horticultural literature by him. 
-- J^enry Bellenden Ker, Esq., died at Cannes, on November 2, at an 
advanced age. He was for some years editor of the Botanical Begister , and some 
quarter of a century ago was an enthusiastic plant-grower, and a frequent contri¬ 
butor to the horticultural periodical press.
