In the same report, it is said that Prof. Hall's second volume 
on Paleontology " the printing is nearly altogether completed/* 
and that some difficulties existed between Prof. Hall and Mr. 
Duthie, the engraver, as to the accuracy and finish of the en- 
gravings. 
The commission recommend that the sum of two thousand 
five hundred dollars be tendered to Prof. Hall, on the presenta- 
tion of each successive volume, commencing with the third, to 
the Secretary of State. The volume should contain the manu- 
script, letter-press, ready for printing, and be accompanied with 
the very fossils described." 
It is also stated in the report that the salary of Prof. Emmons 
ceased on the first of October, 1848, and that of Prof. Hall on 
the first of April, 1849. 
The amount reported to have been expended on the services 
and publication connected with the Natural History, is $17,829.35, 
(See page 35.) 
In the report of the commissioners made to the Legislature 
January 12th, 1852, (see Assembly Doc. No. 23,) they say they 
have closed the account with Dr. Emmons, for the sum of three 
thousand dollars, and that " compensation is understood to pay 
the salary in arrears, and satisfy the whole claim for the comple- 
tion of the volumes on agriculture and entomology now in 
hand." 
Mr. Hall presented an account for salary from April first, 
1849, to October first, 1851, (two and a half years,) deducting 
therefrom four months absence; and he further represented that 
his personal superintendence would still be necessary for several 
months to come, in order to complete the volume in hand; and 
he offered to continue this superintendence at a reduced rate of 
salary." 
" We closed this account on the above conditions, continuing 
his salary at a reduced rate to February first, 1852, and also re- 
quiring that the payments should be in full of all charges of 
every description, in the way of salary or compensation, for the 
sum of $3,625."
