ject: — " To determine by anatomical researches, and by means of accurate 

 figures, the order of the development of the blood-vessels, and the principal 

 changes which the organs of circulation in the vertebrate animals generally 

 undergo, before and after birth, and at the diflferent periods of their life." — 

 1st Jaimary, 1831. 



Prize founded by M. Alhumbert — The academy proposed a prize of 

 1500 francs to the best memoir on the following question : — " To deter- 

 mine by observation, and to demonstrate by anatomical preparations, and 

 accurate drawings, the modifications which the batrachian reptiles, such as 

 frogs and salamanders, present in their skeletons, and in their muscles, on 

 passing from the state of the larva to that of the perfect animal." 



After the adjudication of the prizes, M. Cuvier read an eulogium on Sir 

 Humphry Davy, and M. Arago one on Fresnel. 



August 4. M. Peschier, pharmaceutist of Geneva, announced that he 

 had sought in what species of the willow, salicine is found most abundantly. 

 The Salix incana, and the Salix monandra, variety helix, are the two species 

 which contain most of it. The physicians of Geneva have stopped the 

 progress of intermittent fevers, by administering the salicine, in the dose of 

 15 or 18 grains in the interval of the accession. 



M. Geoffroy St Hilaire made a report on an anatomical model made 

 by M. Auzoux, in pasteboard. The reporter regards this branch of indus- 

 try as being very useful in the teaching of anatomy in colleges and establish- 

 ments where dissection is impossible ; he thinks that M. Auzoux has 

 perfected this art, and that he deserves the thanks of the academy. (Ap- 

 proved.) 



August 9. M. Henri de Cassini made a very favourable verbal report on 

 the Monograph on the CampanulacecB, recently published by M. Decandolle , 

 jun. M. Geoffroy St Hilaire read a memoir on a hermaphrodite goat ; 

 female as to its external parts, and male in its internal organs. (See p. 106. 

 supra. ) 



August 16. M. Geoffroy St Hilaire gave an account of a memoir by 

 M. Courbebaisse, veterinary surgeon at Aurillac, relative to a bicephalous 

 calf. The calf having two hea(]s, and also double anterior extremities, was 

 born on the 20th August, 1827, at Cantal. The academy decreed that 

 thanks should be returned to M. Courbebaisse, and that the beautiful 

 drawing of it which he sent should be engraved in their memoirs, together 

 with the report of M. Geoffroy St Hilaire. 



August 30 In the name of a commission, M, de Blainville made a 



report on the Memoir of M. Deshaies, relative to the analysis of the genus 

 Helix putris. " It results from the work of M. Deshaies, that the organiza- 

 tion of the animal presents differences sufficient to confirm to a certain 

 degree, the establishment of a genus Succinea, such as Draparnaud had defined 

 it, from the consideration of the shell alone ; and that these differences depend 

 essentially on the generative apparatus. It would be interesting to see if 

 the genera Achatina, Bulimus, Puppa, Carocolla, &c. also dismembered 

 from the Helices, present as considerable differences, although this is impro- 

 bable, at least for several of them. 



M. Dumeril gave an account of his examination of the two larvae of 

 insects which Dr Fontaneilles sent to the Academy, and which had been 

 passed by stool by a lady after the use of Scotch pills. The reporter thinks 

 that these larvae, or caterpillars, had been swallowed either with the stalks 

 of cauliflower, or of salads, or with turnips, or some other kind of pot-herb. 



We find in authors many observations of this kind, which, in most cases, 

 have been, like this, considered as the expulsion of intestinal worins. But 

 the knowledge we possess on the structure of insects compared to that of 

 intestinal worms, may, in most cases, direct the observing physician.
