pole, into a perfect frog, she proceeds to describe the gradual transformation of 

 a species of frogs found in great numbers in the river of Surinam, into perfect 

 fishes, and gives 5 figures to illustrate her description ; the subjects she says 

 were then in the collection of Albert Seba at Amsterdam, from whom she also 

 had her figures and information, as appears since by the account published by 

 Mr. Seba of his curious cabinet of natural history, in two folio volumes, a copy 

 of which, finely illuminated, is now in the British Museum.* 



LXI. Of a Remarkable Operation on a Broken Arm, By Mr. Charles White, 

 Surgeon at Manchester. Dated Manchester, March IT th, 1760. p. 675. 



This communication contains an account of a fracture of the humerus in a 

 boy 9 years old, which not being united at the expiration of 6 months from the 

 accident, Mr. White recommended (instead of amputation which had been pro- 

 posed) to make a longitudinal incision down to the bone, to bring out one of 

 the ends of it, (which might be done with great ease as the arm was very 

 flexible) and to cut off the oblique end either by the saw or cutting pincers ; 

 then to bring out the other end of the bone, and to cut off that likewise ; af- 

 terwards to replace them end to end, and then treat it entirely as a compound 

 fracture. This proposal was at length acceded to, and the operation was per- 

 formed. After the dressings were finished, the limb was placed in a fracture 

 box contrived on purpose ; the lad was confined to his bed, and the rest of the 

 treatment was the same as that of a compound fracture. 



The wound was nearly healed in a fortnight's time, when an erysipelas came 

 on, and spread itself all over the arm, attended with some degree of swelling : 

 this by fomentations and the antiphlogistic method soon went off, and the cure 

 proceeded happily without any interruption. In about 6 weeks after the opera- 

 tion, the callus began to form, and was grown quite firm at the above date ; 

 that arm was as long as the other, but somewhat smaller by such long continued 

 bandage ; he daily acquired strength in it, and it was thought he would soon be 

 fit to be discharged from the hospital. 



* The history of the Kana paradoxa of Linneus, and of its tadpole, commonly called the Frog- 

 fish of Surinam, is now much better understood than in the days of Madam Merian and Seba, 

 when the absurdities mentioned in the account here extracted by Edwards, seem to have been gene- 

 rally believed. The larva or tadpole in this species of frog is of larger size than usual, and even 

 exceeds that of the full-formed animal when first arrived at its perfect state. This, however, is 

 not entirely peculiar to the present species, but takes place in some others. In the British Museum 

 is a specimen both of the Rana paradoxa and of its tadpole, which appear to have been wanting in 

 that collection at the time the present paper was written.
