By Martin Barry, Additional illustrations of the author's views on 



this subject. — IV. On the Development of the Decapodce. By H. 



Rathke. This short paper is the contents of a letter written to 



Professor Midler, and is a rough sketch of observation? made by the 



author on the shores of the Black Sea and at Dantzic. The result 



of these researches are rather opposite to those of Mr. Thompson : 



he concludes by saying, " All the Isopodes, with whose development 



I am acquainted, come into the world with fewer bones than they 



exhibit in their state of maturity. These animals, we can say 



with justice and reason, enter the world in an extremely imperfect 



condition ; but as to the Decapods, so far as I have examined their 



development, I must deny such an assertion; and of them I can say 



nothing less, than at the end of their existence in the egg they have 



exactly the same aspect, and are as fully developed, as the full-grown 



individuals." 



Botany. 



Contributions to the Botanical Geography of Southern Europe, 

 by Professor Link, (translated from Wiegmann's Archiv fiir Natur- 

 geschichte, 1836,) and Dr. Graham's list of new and rare plants 

 which have flowered in the neighbourhood of Edinburgh, are the 

 only botanical communications. 



July. Zoology. 



I. On Unity of Function in organized Beings. By William Car- 

 penter, M.R.C.S., Sen. Pres. of the R. Med. Soc, Ed. A paper of 

 considerable merit, suggested by those by Dr. Barry on the " unity 

 of structure." — II. Organic Remains in the old red sandstone of Fife. 

 By the Rev. John Anderson, Minister of Newburgh. — III. On the 

 Fossil Organic Remains found in the Coal formation of War die, near 

 Newhaven. By R. Patterson, M.D. This paper refers to both the 

 remains of plants and animals. The chief plants are Filices, with 

 the genera Catamites, Lepidodendron, Lepidophylla, Polyperices, and 

 Knorria, besides "many which we have been unable to name." 

 Among the animals are abundance of Entomostraca, belonging to 

 the genera Cypris and Daphnoidea, and the author considers the oc- 

 currence of these two, in conj unction with sea- shells and corallines, 

 as an argument against the fresh-water Or lacustrine formation of 

 Burdie-house, as adopted by Buckland and Dr. Hibert from the im- 

 mense deposit of Entomostraca without any marine productions. 

 Five or six genera of fishes with coprolites are also stated to occur.

 garding equivocal Generation. By F. Schulze. An experiment per- 

 formed with distilled water, mixed with various animal and vege-
