This double pear had one part growing over and fixed in the others not 

 unlike an acorn in its cup. From tlie edges of the lower pear grew five leaves 

 of different sizes, at almost equal distances (rom each other. The largest was 

 an inch long, half an inch broad, as large again as the smallest leaf. These

 inner fibres of the pendunculus go through the lower into the upper pear, and 

 disperse themselves in it. The upper part was twice as large as the lower, and 

 had several kernels in it, but the lower none at all.

 Par Mr. Deshayes Gcudron, Docteur en Medecine de ['University de Montpel~ 

 Her. A Paris, iJOO, in 8\o. N° 260, p. 476. 



Mr. Geudron thinks that true cancers are seldom extirpated with success, and 

 that this operation is only suited to those " whose basis ends at once, and 

 which do not send strings to the neighbouring parts." Among topical applica-
