"En la iglesia de Santiago Matatlán, en veinticinco días de diciembre de mil setecientos setenta y dos años, bauticé y puse los santos óleos y crisma a Manuela, hija legítima de Francisco Serna...(next page)(In the margin: Manuela)...y María. Fueron los padrinos Juan López y Josefa, a quienes amonesté su obligación y espiritual parentesco; todos son naturales y vecinos de dicha cabecera, y para que conste, firmé. Agustín Tinoco."

David,

While the request has already been fulfilled, I came here to add that if you have Gemini active in the same window where the image is, it will transcribe the writing for you. I've been using it for help with documents from 1400 and 1500 and has save me hours! It can transcribe a page in seconds, where the task is all but fruitless for me. 

Here's the result for your situation:

"En la Yglia. Parrochial. de Matatlan en siete dias del mes de Dic.re de mil setecientos y sesenta y dos a.s. Baptize solemnem.te a Lazaro Mariano hijo legitimo de Juan de la Serna, y Magdna Mendes fueron sus Padrinos Juanchin Bapt.a y Maria Manla. a quienes amoneste su oblig.on y espiritual parentesco: todos de naturaleza y vec. de dha Cavec.a y para q. conste lo firmo."

I then asked Gemini to translate it into "modern" English (you can do the same into Spanish):

"In the Parish Church of Matatlán, on the seventh day of the month of December, seventeen sixty-two, I solemnly baptized Lazaro Mariano, the legitimate son of Juan de la Serna and Magdalena Mendez. His godparents were Juanchín Baptista and María Manuela, whom I instructed regarding their obligations and spiritual kinship. All are natives and residents of this administrative center; and in witness whereof, I sign it."

Good luck!
