198 SPENCER FULLERTON BAIRD 
From S. F. Baird to William M. Baird. 
CaruisLE, December 6th, 1849. 
Your letter came this morning and the package this 
evening. You need not apologize for the execution of the work; 
it is done most beautifully. I will read over the parcel in a day 
or two and write about it more fully. I am much obliged to you 
for the emendations and improvements. By the way, “bahavia” 
is the technical word for the contact of a mineral before the blow- 
pipe. 
I am glad you liked the minerals. I have two boxes of superb 
Norwegian minerals received from my correspondent, Mr. Aall, 
which I rather think I will lend you till I want them. What say 
you? Iam daily expecting too a lot of fine ores of gold, silver, lead, 
etc. I do not wish to hurry you about the geology, but would like 
it as soon as convenient. It will come on in a few months and Profes- 
sor Agassiz can attend to the revision immediately; still, I want 
you to do nothing to inconvenience or injure yourself. Did I ‘tell 
you of the superb lot of German fish and reptiles I received lately?

The manuscript has gone to Dana, but I have not yet 
heard from him about it. How does the geology flourish? When 
you have got through about half of the matter you have I want you 
to send it to me with the text too of that portion without waiting 
for the rest. The plates can all remain until the whole is finished. 
The article on geognosy as distinguished from geology would make 
.a good breaking off place. 
I got my Rocky Mountain things yesterday. You never dreamed 
of such a pair of elk horns with the skull and skin of the head. They 
make two of Colonel Tuley’s. Their weight is over fifty pounds, at 
which they are charged in the bill of freight. There were two nicely 
stuffed antelopes male and female, and a beautifully prepared head 
of the black tailed, or mule deer.
