similarity of tlie soil at Seychelles with that of the Great 
African Island. 
The presence in our forests of one of the tallest and 
most useful trees, in Mauritius, was during several years 
and even in the life time of Bojer, the subject of an 
animated correspondence between our Society and Prof. 
Alp. de Candolle at Geneva and Dr Hooker, of Ptoval 
Gardens at Kew. 
Prof. Alp. de Candolle was the first who raised the 
question addressed on the first instance to Bojer — What 
are the plants of which the fruits were indicated by 
Grertner under the generic name of Calvaria ? Dr Hooker 
asked for the same information, and the question was 
long insolved. 
But from a copy made by Prof, de Candolle of a drawing 
of a seed of the Calvaria major in the Fructibus fy Semi- 
nibus of Gsertner, and forwarded to your Secretary, Mr 
A. Daruty was fortunate enough to recognize the fruit 
of the tree known under the name of Tambalacoque, and 
described by D. C. in his Prodromus as the Sideroxylon 
Boutonianum. 
The question has thus been settled and seeds and flowers 
have been sent to Dr Hooker to be described in the Flora 
of Mauritius just about to be published. Specimens have 
also been sent to Prof. D. C. who will probably make 
them the subject of a special work. 
The Society is also indebted to our colleague M r A 
Daruty for the following papers :
