Elemental Composition of the Body is a simple table that lists, in descending order of abundance, all 59 chemical elements present in measurable amounts in the human body. For each element, the table shows 1) the weight of element present in a 70-kilogram person, 2) the volume occupied by that much of the purified element, and 3) how big a cube made up of that quantity of purified element would be.
"The Red Cell and Anemia" is a companion to a sophomore med student lecture I give on this subject. It is 51 pages long, 19000 words, and has line drawings and tables. It is just about everything you would need to teach red cell diseases to med students and medical technology students. 228K.

This is a collection of specimen images that I have released into the public domain. The index page is
The image files are all JPEG with longest dimension between 550 and 650 pixels.
Since my ISP limits my space here severely, I have begun to add specimen images to a section in my Flickr account. The images there have much higher resolution than those here.
Other binary files
"Placenta" is a downloadableStuffit archive containing my spreadsheet for calculating normal ranges of placental weights and plotting an individual patient's placental weight on the resulting nomogram. The spreadsheet can be modified with your institution's logo and your personal signature line by anyone who has a bit of working knowledge of Microsoft Excel. There are two files in the archive. PLACENTA.XLS is the spreadsheet template itself, and PLACDOC.TXT is documentation on how to use the spreadsheet. Public domain, 15K.
"Grouper" (version 2.1) is a Microsoft Excel worksheet that accepts up to 1000 numerical datapoints, calculates descriptive statistics of the sample, collates the data into a user- specified number of groups, and draws a histogram of the grouped data. It can also accept user-specified exclusion criteria, allowing outliers to be filtered out of the dataset before the histogram is constructed. I developed it as an aid to determine lab test reference ranges. This is a Stuffit archive containing the spreadsheet, GROUPER.XLS, and the documentation, GROUPER.TXT. Public domain, 56K.
"A Taxonomic Guide to the Pathology Kingdom" is a PowerPoint presentation on pathology as a career, comparing the world of academic pathology with that of private practice. This will be pretty obscure for anyone who is not fascinated by scientific names of biological species. You have been warned. 44K.
