ADDENDA ET CORRIGENDA.

new undertaking, should have been rendered more disastrous by the party spirit with which the whole subject appears to have 
been agitated, even in tlie Legislature. 
It is extremely unpleasant to come in contact with such a state of things, and I find that I am censured for not being suffi- 
ciently one-sided in the dispute. The writer in ‘Grids’ says “Mr. Howard, who described the unfortunate sort as a new 
species in his noble work on the Cinchonse, although he at first, with reason, brought its usefulness into question, afterwards took 
a position of weakness and uncertainty as the conflict began to wax warm,” etc. 
To this I have only to reply that I have published such information as came to my hands as correctly as I could, and intend 
still to do so. I see no occasion to alter my account of the species given in the ‘ Nueva Quinologia/ and still believe that it is 
without value if looked at simply as a source for the extraction of Quinine ; but as regards the root-bark, I have, personally, no 
information to oppose to the favourable estimate elsewhere entertained, and must therefore maintain a position of “ uncertainty ” 
till this is removed by those who can decide the question. If the G. Pahudiana be looked upon in another point of view, viz. as a 
possible source of bark for pharmaceutical purposes, I have shown in my reports, given to the Government of British India, on 
specimens from Ootacamund, that the quill bark is not only not worthless, but that such quills as those sent by MTvor were 
actually preferred to other kinds sent with them by dealers most competent to judge in London ; and this not without reason, from 
their taste, appearance, and chemical composition. I cannot, therefore, agree with those who recommended the superfluous labour 
of cutting down the trees ; neither can I rank this plant “ among the best sorts of all,” as, it seems, some have attempted to do. 
The trees, having now many years’ growth, might, perhaps, furnish quill bark fit for the home market ; and I shall be surprised if 
it is not at least equally valued there with the bark of the so-called G. Calisaya, which, I am afraid, will prove “ unfortunate ” also ; 
at least if it produces but T3 per cent., as described by Van Gorkom. 
I have now specimens of the G. Pahudiana in healthy growth, and am confirmed in my view of its being a new species, 
“ quite distinct,” as Dr. Weddell avers, from the C. Carabayensis. 
Dr. de Vrij remarks :* — 
“ Tandis que le gouvernement neerlandais, eclaire par ses savants conseillers (voyez c De Grids/ inai 1868), considerait comme 
superflue la presence d ; un cliimiste, charge specialement d'eclairer sans discontinuity de ses lumieres et de ses experiences la marche 
de la culture des cinchonas et faisait detruire (ce qui a ete execute par les ordres du gouverneur general Hcet Van de Beele a la fin 
de 1863) le laboratoire de chimie qui avait ete erige a grands frais a proximite des plantations de cinchonas, le gouvernement 
anglais a ete precisement d^une opinion tout opposee et a envoy e dans ce but en 1866 M. Broughton a Ootacamund. La represen- 
tation nationale des Pays-Bas parait toutefois partager V opinion du gouvernement anglais : cela resulte de ce fait que la deuxieme 
chambre des Etats-Generaux a donne le 14 juillet 1865 son approbation an rapport de la commission choisie dans son sein pour 
examiner les pieces produites par le ministre des colonies relativement a la culture des cinchonas a Java: or ce rapport se termine 
de la maniere suivante. 
c Pour atteindre le resultat desire, il sera du reste necessaire d^etudier sans discontinuite dans des conditions diverses avec tous 
les moyens fournis par la science les differentes sortes de cinchona poussant actuellement a Java, afin ae pouvoir ainsi arriver h con- 
naitre dans quelles circonstances il se forme dans kecorce une quantite de quinine aussi grande que possible. 
j\ est facheux que le gouvernement n’ait paru tenir aucun compte de ce desir et que nous soyons par suite encore actuellement 
fort peu edifies sur les conditions dans lesquelles a lieu dans les differentes especes de cinchona la formation, de la plus grande 
quantite possible de quinine.” 
1 have only to add, in justice to Dr. Vrij, that it did not occur to me, whilst referring in page 6, to the solicitude with which 
I conducted the first experiment on bark of G. succirubra from Ootacamund, to state that Dr. de Vrij had previously obtained and 
described alkaloids from the plantations in Java. (See the f Repertoire de Chimie/ October, 1860, p. 315.) 
M. HARDY, SHE LA CULTURE DU QUINQUINA EN ALGERIE. 
The above pamphlet has been sent me by M. le Dr. J. L. Soubeiran. It is valuable to all who have any intention of commencing 
Cinchona plantations in any extra-tropical region. It has confirmed me in a fear, which the experience of the past summer of 1868 
has induced in my mind, that I have spoken rather too sanguinely in the early portion of this work of the possibility of any member 
of the family becoming at all acclimatized in our regions. The heat and drought of summer and the frosts of winter seem almost 
alike inimical to the success of the enterprise. 
CULTIVATION OF CINCHONA IN TEXAS. 
Dr. Thomas Antisell appears to have prepared a memoir on this subject, which forms part of the Commission of Agricultui e foi 1866. 
Seeds of the G. succirubra and Gondaminea were procured by the United States Minister residing in Ecuador. The lattei 
only germinated in 1864, in the experimental garden of the Department of Agriculture at Washington, but owing to unfavourable 
circumstances the plants were but weakly, and it was intended to transport them to more propitious regions. 
It had been supposed that Texas might present favourable localities, but these, according to Dr. Antisell are more likely to be 
found towards the frontiers of Mexico, below the zone of the Sequoia. ( e Journal de Pharmacie et de Chimie/ Jan. 1869.)
