Summary

Thanks JM for his liberal offer [to publish Orchids]. CD fears the public will not be interested, but thinks it will "do good to the Origin as it will show that I worked hard on details and it will perhaps serve [to] illustrate how Natural History may be worked under the belief of the modification of Species".

Summary

Thanks for gift of treatise on Coelenterata [? Manual of the sub-kingdom Coelenterata (1861)]. "… I was but lately wishing to read some treatise up to the present mark, on these animals. I have cut the pages & can clearly see that your work will much interest & instruct me".
