f ' Mr. E H Aitken, at the monthly meeting of the 
'^iBdnlbay Natural History Society on Timraday, 
the 16tii instant, said that it was proposed to make 
B8 complete a collection as possible of the mos- 
quitoes of India, and tlie Comnjittee hoped that 
niembeis would help by sending them specimens 
of the kinds which paid them attention. Tlie im- 
portance of a kuowiedt;e of (.he diflerf nt species 
of mosquitoes could scatce-y be f-.-cagicrated in iLe 
Mfi[hc Oi iccent di.'coveiifs ; but oi ine lUHuy 
medical men in India whom it concerned to know 
• tliein, few had liie opportunity or taue to 
• '^n'ake large collection, and wiihoui a refer- 
• ebce collection, identtlicaiiou was very ditlicult 
if uot impossible. To 'nake and keep such a col- 
lection would be altogether in line with the hon- 
ourable career of usetulness which had distin- 
guished the Society in the past, and there could 
be no question that it ought to be commenced at 
once. Mr Aitken then showed how mosquitoes 
-■''Were killed, pinned and preserved, and said if 
'' 'tiaembera were uot disposed to take the trouble 
' of performing the operation themselves they might 
send live mosquitoes to the Secretary in small 
bottles or glass tubes, A vote of tnauks was 
passed to Mr. Aitken, ami the meeting then ter-

:>*!rROUT- PISHING ON DERWENTWATER. 
'A'' meetilQg convened bj^' Mr Tindall Harris 
'';'vvas held at Keswick yesterday afternoon, at 
'Hvhich the riparian owners of Derwentwater 
'-'■'iitid other were present. Canon Rawnsley, who 
was in the chair, explained the object of the 
■'tileeting, which was to restock Derwentwater 
'^['with lake trout and to take such steps as were 
iiecessary in killing oft pike and perch and in 
'Wiitching the spawning beds. He quoted 
■'"-PrAnk Buckland's dictum after his visit in 1878, 
' thtit this district was the most magnificent fish 
farm iu Her Majesty's dominions, and went on 
to show that, with a splendid bottom feed, a 
rise of the green drake, and water undisturbed 
by boating for three quarters of the year, 
there was a fair chance of making Derwent- 
water as good a stretch of troutiug water as 
'Lake Vyrnwy or Loch Leven, while the lake 
'' Was so sitmited in relation to Lancashire and 
'' the North as to be of great concern to the 
ifisherman who had neither time nor money to 
as far afield as Scotland or Ireland. An 
executive committee was elected, and an ap- 
' penl for funds decided on,— London Times,

THE BAMBOO PARTRICOE. 
(TO THE EDITOR OF THtO " INDIAN FIELD.") 
Sir,— Is the so dubbed bamboo partridfe a dis- 
tinct species or only a freak of nature ? Is it ever 
seen in the plains? or like the Spur Fowl of the 
Nilgiris only found in the hill.s. An acq-iaintauce 
asserts the bird is not a partridge at all, but a 
quail. Avis. 
[These very haud:=ome birds {Bcoabmicola Fijtcldi) 
are probably a coouecting link between the pheaaanta 
and partridges. Tnev form a small group of game 
birds in the Bnia ^-C linese country and occtir in the 
Khasi and Garo H ' s, the North Caohar and INaga 
HiMs and in Manipnr. They approach the pheasants 
in the shape of the wine; and are rather closely allied 
to the Spur Fowl. — Ed. J

"ORANGE" PEKOE IN CH/NA 
Affn HOW ir IS MADE. 
Scarcely less fragrant than the fiower fields of 
France are the tea orchards of China and Japan, 
rhat a'e ready for the first picking of h.-aves. The 
leave-;- have H de ightfui f'-agranc*", and, too, in 
Souiheni China orange tc-i are often gioun in the 
same planuuioii.s, for the "nder tip leaves of tea- 
that are to be cured as Orauge Pekoe, are cured 
on screens above trays of orange petals. In dry- 
ing, the tea actually takes up a perceptible perfume 
from the orange blossoms. This tea commands a 
fabulous price in the market, and most of it is kept 
in China for the court and provincial mandarins. 
It would seem as if April were specially favoured 
with fragrant crops. The coffee season has begun 
on the plantations of Brazil, to continue for several 
months. There is thyme, sase and mint in France,

THE CAMPAIGN AGAINST MALARIA. 
, . A N£W DEPAKTUKE. 
In . a communication made by liim to the April 
number of the hidiun Medical Gazette, in the 
shape of gleanings from the Atte delta Societa 
ver qli bUuli delta Malaria (Proceedings of the 
Society for the luvestigation of Malaria), Lieute- 
nant-Colonel Giles, I xM S (Itetired), gives an 
interesting account of certain observations whicii 
if verified, are not unlikely to lead to a new 
departure of great Importance in the campaign 
against malarial ^'-sease. It is an established 
fact, says tiie Sta srncm. that the physical con- 
ditions known t. fa\our the development if 
malaria, even wht n combined with the presence oi 
swarms ofanopht"'s of the susceptible species 
may exist witho gi\ing rise to the diseaso. 
Hitherto this faci has been att ibuted to theal* 
sence of ipfectcd hiiman beings, and in many 
instances it may be unnecessary to look further 
for an explunatio ■ of it. But it has been ascer- 
tained that in an jltitude of cases not only does 
such innnunity cc-e.'iisi with the proximity of 
active foci of the disease of gieaO/ virulence, but 
the introduction of iufected persons into the 
imnuine areas is unattended by the development 
of niitlaria, The inf^'rence is thus sngge-^fed that 
the mosquitoes of the innuune areas are for some 
reason insusceptible of infection. No explanation 
of such an immunity is, however, iu many cases to 
be found iu change of local conditions, where 
the area^ iu which it occurs had bcea violently
