My distinguished friend:



I am hoping you will kindly excuse myself for troubling you once again, but remembering always your exceedingly good attitud toward our University.  I am taking advantage of this fact to ask to use your valuable influence before the President of the Carnegie Institute, so that the Bilogical publications that your great Institution sends to Mexico may be conveyed directly to our Institute.  I propose this agreement due to the fact that the library of our Institute is the only one specialists in Biological Sciences in the entrie country.  This library is consulted by physicians, bilogists and other people intrested in these subjects.



It is also true that in the City we have the National Library and others, but they are specialists in other branches of Sceince, as Geology, Geography, History, Mathematics, etc.  The Library the Institute of Biology that we carefully look after is the only one in charge of Biological Sciences, opened daily to everybody interested in Biological knowledge.  We specially wish to obtain the publications of the embryological series, the series of Zoology and Botany published by the liberal aid of Mrs. Andrew Carnegie.



You already know all about aou economical conditions - which worse than ever before prevent us from the acquisition of new books and pulication as we would desire.  I am sure that your influence will be valuable in our petition, and it will render a great service to many mexican investigators, generally poor, and without elements to do efficient work, but very enthusiastic in the field of science.
