118 TRANSACTIONS OF THE 



articulate animals and insects, and the metamorphoses of insects, and how 

 they propagate their species, and said that to exterminate any one of a nox- 

 ious class of insects, we must encourage the increase of an innocent race. 

 For instance, it would be impossible to destroy the larva of the insects that 

 prey upon our city shade trees by human hands, but we could encourage 

 birds that prey upon them, so as to get rid of all their ill effects. And so 

 of a great many other noxious things ; if we knew more of them, we could 

 easily find an antidote for their depredations, by means of some harmless 

 insect, bird or animal, the natural food of which are the things which we 

 wish to get rid of. 



Dr. Waterbury dissected a lobster showing that it contained teeth for 

 further mastication of its food. He showed its heart, situated under and 

 near to its back — and the circulation of its blood — hsLving fo?-iy puis at io?i3 

 a minute, ^-c. The most learned persons present were much pleased with 

 these phenomena and with Dr. Waterbury's very intelligent easy manner 

 of demonstration, and by his large drawings, and on the blackboard. 



Mr. Solon Robinson offered the following resolution, which was seconded 

 by Prof. Mapes, and carried unanimously, viz : 



Resolt'cd, That the lectures of Dr. Waterbury upon the structure and 

 functions of insects and animals and plants, are well worthy of repeti- 

 tion before all the schools of this country, as they contain matter that 

 should be learned by every child in America, and can be learned by the 

 lucid manner of teaching by Dr. Waterbury more rapidly than by any 

 other mode in common use ; and therefore it is the opinion of this club, 

 that we may benefit others by recommending such a course of lectures 

 as the doctor is capable of giving, before schools and agricultural socie- 

 ties. 



A CURIOUS CASE IN HOG CHOLERA. 



Solon Robinson. — I have a letter detailing a curious case connected with 

 the disease of hogs, called cholera, that I beg to call attention to now, and 

 perhaps Dr. Waterbury may suggest a remedy. At any rate it is a sub- 

 ject for thought. E. C. Wright, of Gallatin county, Illinois, states, on 

 the authority of the Rev. John Crawford, of Crawford, in that county, that 

 the bones of swine dying with what is called hog cholera, decay as rapidly 

 as the flesh, and that portions of the skin outlast the bones. He wants 

 scientific men to give attention to this strange consumption of the solids, 

 and thinks that it may be the means of suggesting a remedy for the disease 

 BO fatal and so pecuniarily distressing to a vast number of farmers in the 

 west. Now, as we know that feeding bone meal to animals and phosphate 

 of lime to plants that need it, has proved beneficial, is it impossible or im- 

 probable that feeding it to swine ,sufi"cring from a disease that produces 

 the efiect described, may not be the means of curing or preventing the 

 disease ? 



Dr. Waterbury. — There are some new theories in relation to feeding 

 phosphates to animals. It is possible that this may have some effect.
