Dear Sir; Just now I have received a circular from the Committee of Organization appointed by the Imperial and Central Horticultural Society Of Paris, of which the following is a translation:

"Sir - The horticultural products cannot be admitted at the Universal Exhibition - it being exclusively devoted to the productions of Art and Industry; but the Government authorized the Imperial and Central Horticultural Society to make an appeal to all horticulturists, both French and foreigners, and to organize, from the 1st of May to the 31st of October, a permanent and universal Horticultural Exhibition.

"In consequence, the Society is preparing, at the Champs Elysec, a vast garden with spacious green houses, where the products destined for the exhibition will find all the material accommo dations, as well as all the attention, required for their preservation.

"The Society's appeal addresses itself to all the branches of cultivation - plants, flowers, fruits and vegetables, from all climates, as well as to all the agricultural productions so intimately connected with horticulture.

" The Society will be glad to receive the industrial productions destined for horticulture.

"At the close of the Exhibition, rewards will be distributed to those selected by the jury.- The general regulations will soon be published. Meanwhile the Society requests all the horticulturists and amateurs to inform them as soon as possible in respect to the following:

" 1st, Of the nature and quantity of the products they destine for the Exhibition.

"2d, The time at which these products may be forwarded, and how long they will be allowed to remain on exhibition.
